23       
24    - 1.25alpha3 (2006-05-11) :
25   
26        - Added a lock to ensure that a single cupspykota backend
27          is processing datas for a particular print queue at any
28          given time.
29         
30        - Now exports more environment variables for the subprocesses.

40        - Make the MySQL schema work with old releases of MySQL.
41       
42        - Fixed several character encoding problems.
43         
44        - Ensures that the denied banners counter is properly initialized
45          with relationnal databases.
46         
47    - 1.24 (2006-04-08) :
48   
49        - Improved documentation and packaging stuff.
50       
51    - 1.24beta (2006-03-26) :
52   
53        - Finalized the pknotify command.
54       
55        - Updated the messages catalogs for translations.
56       
57    - 1.24alpha18 (2006-03-15) :
58   
59        - Now uses MIME encapsulation for email messages to avoid

63   
64        - Fixed a major problem in the PostgreSQL backend.
65       
66        - pknotify can now check a remote user's name and password.
67       
68    - 1.24alpha16 (2006-03-02) :
69   
70        - Introduced the pknotify command line tool to dialog
71          with remote PyKotIcon applications.
72         
73    - 1.24alpha15 (2006-03-02) :
74       
75        - optimized pkbcodes, pkprinters and pkusers using edpykota as
76          the model.
77       
78        - 'edpykota --list' and 'pkusers --list' are now authorized
79          to mere mortal users, but the list is restricted to informations
80          about the current user.
81       
82        - Extended the functionnality of the 'onbackenderror' directive to
83          allow for configurable retries.
84         
85    - 1.24alpha14 :
86   
87        - Finished optimizations in edpykota and fixed some minor
88          problems with LDAP.
89         
90    - 1.24alpha13 :
91   
92        - Introduced the pkusers command line tool to manage users and 
93          users groups. This command doesn't deal with print quota entries,
94          which continue to be managed through the edpykota command line
95          tool.
96         
97        - Major rewrite and incompatible changes to command line options
98          in edpykota. This command now only deals with print quota
99          entries. Printers, users (or users groups) now have to be created
100          first using pkprinters or pkusers.
101         
102    - 1.24alpha12 :
103   
104        - Introduced the 'duplicatesdelay' directive to specify after
105          which duration two duplicate jobs are not considered duplicate
106          jobs anymore.
107         
108        - Introduced the 'balancezero' directive to specify any value 
109          as the balance limit instead of 0.0. This can allow admins to
110          give a few free credits to users, for example.
111         
112    - 1.24alpha11 :
113   
114        - Huge speed improvements when modifying billing codes and
115          printers.
116       
117        - Both pkbcodes and pkprinters now display the percent done
118          for all actions.
119         
120        - The pkinvoice invoice generator command line utility is now
121          included.
122         
123    - 1.24alpha10 :   
124   
125        - Huge speed improvements when deleting users, printers, and
126          billing codes.
127         
128    - 1.24alpha9 :
129   
130        - Preliminary support for MySQL, thanks to Matt Hyclak.
131       
132    - 1.24alpha8 :
133   
134        - The 'preaccounter' configuration directive was introduced to control
135          which parser to use for precomputation of the job's size. When unset,
136          the internal parser is used just like it was previously. See
137          conf/pykota.conf.sample for more details.
138         
139        - Now subprocesses launched through the overwrite_jobticket directive
140          can also output 'CANCEL', to represent the user's own choice to
141          cancel the print job.
142         
143    - 1.24alpha7 :
144     
145        - pkbanner now handles new print limiting modes correctly.
146       
147        - The cupspykota backend wrapper now accepts to be interrupted
148          with a kill -INT. This causes an immediate and clean abort
149          of the current print job.
150         
151        - Matt Hyclak contributed the possibility to store the printing
152          history in a MySQL database. See the contributed/ directory
153          for details.
154         
155        - Added 2006 to the copyright's years.
156       
157    - 1.24alpha6 :
158   
159        - Fixed internal SNMP and PJL handling code for very fast
160          printers : PyKota didn't see them going from 'idle'
161          to 'printing' to 'idle' again.
162         
163        - Now waitprinter.sh accepts SNMP version number and
164          community name as arguments, thanks to Brandon
165          Holbrook.
166         
167        - Now command line errors and Ctrl+C repectively cause
168          PyKota commands to exit with status -2 and -3.
169         
170    - 1.24alpha5 :
171   
172        - All command line tools now accept -A | --arguments filename.args
173          as a way to bypass the shell's maximal command line size :
174          just put each argument on a line by itself in a file, and
175          pass the file's name as the -A | --arguments command line
176          option's argument. For now this won't be documented in
177          commands' helps.
178         
179        - dumpykota can now dump the complete database in XML
180          format.
181         
182    - 1.24alpha4 :
183   
184        - Added support for the SQLite3 backend.
185          See pykota/initscripts/sqlite/README.sqlite
186       
187    - 1.24alpha3 :
188   
189        - Fix for mailandpopup.sh : smbstatus can't be run setuid,
190          so we regain priviledges before running an external
191          mailto directive.
192       
193    - 1.24alpha2 :
194   
195        - Introduce the "onbackenderror" directive in pykota.conf, to
196          control if the user must be charged or not whenever a real
197          CUPS backend fails. The default value is 'nocharge'.
198          Set it to 'charge' if you think your users can cause a CUPS
199          backend to fail.
200         
201        - Now mark original backends related problems as such in the
202          printing history. Modified printquota.cgi and pykota.css
203          to make them be more visible.
204         
205    - 1.24alpha1 :
206   
207        - Fixed a problem which caused backend errors to be ignored.
208       
209        - The sample LDIF file now contains the two necessary user
210          entries to have an LDAP PyKota Admin and an LDAP PyKota
211          ReadOnly user. The sample configuration files were updated
212          to contain the default passwords used in the LDIF file.
213         
214        - dumpykota is now more strict when checking arguments.   
215       
216    - 1.23 :
217   
218        - Many minor bug fixes and code cleaning.
219       
220        - Improved documentation.
221       
222        - Added Polish translation.
223       
224        - Improved French and Swedish translations.
225       
226    - 1.23beta :
227   
228        - Now the mailto directive is honored in all cases where the job is
229          denied or a warning has to be issued, and the correct reason
230          can be sent back to the user.
231         
232        - The PYKOTAREASON environment variable, if defined, contains the 
233          textual reason why the job was denied or a warning has to be
234          issued.
235       
236    - 1.23alpha31 :
237   
238        - Added support for --maxjobsize, --passthrough and --nopassthrough
239          in pkprinters. These modes are now also honored when printing.
240         
241        - Allows the admin to restrict the number of print queues which will
242          be treated by pkturnkey by passing queues' names as additionnal
243          arguments on pkturnkey's command line.
244         
245        - pkturnkey now supersedes pkhint with the help of the -c | --doconf
246          command line option.   
247         
248    - 1.23alpha30 :
249   
250        - Database changes : you MUST use upgrade-to-1.23.sql again if you
251          use PostgreSQL, or copy the new schema and restart your LDAP
252          server if you use LDAP.
253         
254        - The -C | --comment command line switch was added to edpykota to 
255          attach textual information to modifications done to a user's
256          account balance.
257         
258        - The -l | --limitby command line switch to edpykota was modified 
259          to allow 'noquota', 'nochange', and 'noprint'. See the edpykota
260          command's help or manual page for details.
261         
262        - The -i | --ingroups command line switch to repykota allows 
263          PyKota Administrators to only lists members of the specified
264          group or groups (separated with commas).
265         
266        - The -I | --increase command line switch to edpykota allows
267          to increase or decrease page limits.
268         
269        - Added the precomputed job's size and price to the history
270          for controlling purpose.
271       
272    - 1.23alpha29 :
273   
274        - Fixed a small problem with billing codes.
275       
276        - Exports some environment variables earlier, to render the script
277          launched by the overwrite_jobticket directive more powerful.
278         
279        - Now autopykota also creates print quota entries for the user on the
280          printers groups the current printer is a member of.
281         
282    - 1.23alpha28 :
283   
284        - Added users groups management to pkturnkey.
285       
286        - Fixed umask in setup script.
287       
288    - 1.23alpha27 :
289   
290        - Replaced the --dryrun command line option by the --force
291          command line option in pkturnkey, with exactly the opposite
292          effect (for security reasons).
293         
294    - 1.23alpha26 :
295   
296        - Allows parametrized pjl and snmp hardware accounting methods,
297          to be able to respectively set the TCP port and the SNMP

303       
304        - Improved pkturnkey's general usability.
305       
306        - Added a manpage for pkturnkey.
307       
308    - 1.23alpha24 :
309   
310        - Allows different databases to be used depending on the
311          user's rights. This allows PyKota admins to directly
312          use a master LDAP server for read+write, while letting
313          normal users using the replicas for readonly access.
314          NB : using different storage backends is also possible,
315          but you're on your own there.
316         
317    - 1.23alpha23 :
318   
319        - Fixed a problem with banner accounting.
320   
321        - Introduction of the new 'pkturnkey' command line tool.
322       
323    - 1.23alpha22 :
324   
325        - The cupspykota backend was almost entirely rewritten from scratch.
326          It's now much more readable, maintainable, etc...
327         
328        - LPRng support is OFFICIALLY dropped for now. LPRng users are 
329          advised to download earlier releases or purchase the
330          PyKota v1.22HotFix1 Official release. LPRng support
331          MIGHT be re-added later.
332       
333    - 1.23alpha21 :
334     
335        - Fix for IPP requests which contain more than a single
336          job-originating-host-name attribute.
337         
338    - 1.23alpha20 :
339   
340        - Added the overwrite_jobticket directive. See pykota.conf.sample
341          for how to use it.
342         
343    - 1.23alpha19 :
344   
345        - Fixed an LDAP filtering problem when managing billing codes.
346       
347        - Added the unknown_billingcode directive. See pykota.conf.sample
348          for how to use it.
349       
350    - 1.23alpha18 :
351     
352        - Added the dump_bfd.php contribution.
353       
354        - Several fixes in the internal PJL accounter.
355       
356        - Now autopykota doesn't create unneeded print quota entries anymore.
357       
358        - Increased the timeout in the PJL hardware accounting code to
359          accomodate some printers (HP5000 at least).
360         
361    - 1.23alpha17 :
362   
363        - pkpgcounter is now distributed separately only. This
364          means that people must now download and install pkpgcounter
365          v1.56 or higher prior to being able to run PyKota.
366         
367        - Removed all the autoconf/automake stuff which was outdated 
368          and confusing.
369         
370    - 1.23alpha16 :
371     
372        - Extracted the GPL blurb from all commands' help, and use
373          a static version only once. This saves space big time, and
374          eases future translations.
375         
376    - 1.23alpha15 :
377   
378        - pkbcodes now works with the PostgreSQL backend.
379          NB : PLEASE RUN upgrade-to-1.23.sql AGAIN !!!
380       
381    - 1.23alpha14 :
382   
383        - Logs a warning when the user/group doesn't exist when running
384          edpykota.
385         
386    - 1.23alpha13 :
387   
388        - Minor fix for user groups because of latest database changes.
389       
390    - 1.23alpha12 :
391   
392        - Big database changes, use the migration scripts !
393       
394    - 1.23alpha11 :
395   
396        - Small fix to the PCL3/4/5 parser for some drivers.
397       
398    - 1.23alpha10 :
399   
400        - Fixed a bad exception name in cupspykota when parsing IPP messages.
401       
402        - Improved the IPP messages module : it can now generate IPP messages
403          in addition to parsing them.
404       
405    - 1.23alpha9 :   
406   
407        - The denyduplicates directive now accepts a command line as an
408          argument beside yes/no. The command is launched and must
409          print either ALLOW or DENY to its standard output. Then the
410          job gets allowed or denied by PyKota.
411          This will allow user interaction in the near future.
412         
413        - Introduced the new 'striptitle' directive to remove ugly prefixes
414          from print job's titles whenever a new print job is submitted.
415         
416        - Fixed internal SNMP accounter for printers which only have a life time
417          page counter, and not a volatile page counter.
418         
419    - 1.23alpha8 :
420   
421        - The data dumper can now summarize payments and history with the
422          help of the --sum command line option (or checkbox in the CGI).
423         
424        - The message used when the job's filename, title and options are
425          hidden because of the privacy directive is now translated at
426          retrieval time, instead of at saving time.
427         
428        - Minor fix in the LDAP backend code. 
429         
430    - 1.23alpha7 :
431   
432        - Improvements to the internal PJL and SNMP accounter : now should
433          support more printers and waste less time.
434         
435    - 1.23alpha6 :
436   
437        - The data dumper's start= and end= date filtering options now
438          accept a positive or negative offset to be added to the special
439          keywords 'yesterday', 'today', 'now', 'tomorrow'.
440          e.g. : dumpykota --data history start=yesterday-5 end=today
441         
442    - 1.23alpha5 :
443   
444        - The data dumper's start= and end= date filtering options now accept
445          the special keywords 'yesterday', 'today', 'now' and 'tomorrow'.
446         
447    - 1.23alpha4 :
448   
449        - The data dumper now accept start= and end= to specify the starting
450          and ending dates to dump the history.
451         
452    - 1.23alpha3 :
453   
454        - The destination link for the logo used in CGI scripts is
455          configurable.
456         
457        - Data dumper improved : it's faster and now datas are correctly
458          escaped.
459       
460        - The URL to the logo displayed in the CGI scripts is configurable.
461       
462    - 1.23alpha2 :
463   
464        - Fixed edpykota --prototype with balance.
465       
466        - Major rewrite of the IPP message parsing code to definitely
467          fix the job-originating-hostname IPP attribute problem.
468       
469    - 1.23alpha1 :   
470   
471        - Sets current username to the user CUPS runs as instead of "root"
472          when printing test pages from CUPS' web interface (because
473          the username is empty in this case).
474         
475        - Fix for strange values in job-originating-hostname
476       
477    - 1.22 :
478   
479        - Big improvements to the documentation.
480

508          and exported to subprocesses as the PYKOTAJOBBILLING environment
509          variable.
510         
511        - Ctrl+C now makes PyKota commands exit without a traceback.
512

535   
536        - Fixes some case related problems with some LDAP backends.
537       
538        - Fixes some problem for printers which directly go from

540          returning to "idle".
541         
542        - Some permissions settings may have prevented cupspykota
543          from parsing cupsd.conf, this is now fixed.
544         
545    - 1.22alpha2 :
546   
547        - Introduction of the web enabled print quote generator.
548       
549        - Fixed a potential race condition when several backend

580    - 1.21alpha27 :
581   
582        - Allows software() (no arguments) to the software accounting
583          directive. This saves a lot of CPU since the job is not
584          parsed again : the precomputed size is used directly in this
585          case.
586         
587        - epykota's --prototype option now works fine with accounts
588          limited by balance.

602         
603        - Introduction of the new 'trustjobsize' configuration directive
604          to workaround some problematic printers. See the sample
605          configuration file for details.
606         
607    - 1.21alpha24 :
608   
609        - Big database structure changes. An upgrade script
610          is now included for PostgreSQL. LDAP users may just
611          want to copy the new schema in place.
612         
613        - edpykota now recognizes the -o | --overcharge command line
614          option to set an overcharging or undercharging factor
615          on each print job's cost for a particular user.
616         
617        - repykota's output format has changed an is not limited to 
618          80 characters wide anymore. People who used to parse
619          repykota's output in their own tools are strongly advised
620          to parse dumpykota's output instead.
621         
622        - Introduction of the new 'maxdenybanners' configuration directive
623          to allow up to N (the directive's value) deny banners to be
624          printed even if the print account is forbidden to print.
625         
626        - Better detection of the number of copies in the PostScript parser.
627

633       
634    - 1.21alpha22 :
635   
636        - edpykota's --delete command line option doesn't consider
637          '*' to be the default argument anymore :-)
638         
639    - 1.21alpha21 :
640   
641        - dumpykota.cgi can now be run as a normal user as opposed to
642          a PyKota administrator. No read access to pykotadmin.conf is
643          necessary anymore. This CGI scripts now honors the REMOTE_USER
644          environment variable just like printquota.cgi does, see
645          the file cgi-bin/README for details.
646          The command line tool dumpykota must still be run by a PyKota
647          administrator.
648         
649        - Fix exception's name error due to a change in recent versions
650          of PygreSQL.

654        - Big bug fix wrt the datelimit field which was never reset.
655         
656    - 1.21alpha19 :
657   
658        - Introduction of the new dumpykota.cgi CGI script, which
659          allows third party tools like phpPrintAnalyzer to be
660          interfaced in real time with PyKota. To use it you
661          may have to change your web server's configuration,
662          please see pykota/cgi-bin/README
663         
664    - 1.21alpha18 :
665   
666        - Now dumpykota can dump the job history into CUPS' page_log
667          format (even when the printing system is LPRng). This allows
668          people to use tools like PrintAnalyzer or phpPrintAnalyzer
669          (two completely different beasts) with PyKota.
670         
671    - 1.21alpha17 :
672     
673        - Fixed field type's name in XML dumps.

690        - dumpykota filtering capabilities are now supported within
691          the LDAP backend too.
692         
693    - 1.21alpha14 :
694   
695        - dumpykota now supports extended filtering possibilities
696          with the PostgreSQL backend (LDAP support will come soon).
697         
698    - 1.21alpha13 :
699   
700        - Added a --debug command line option to pkpgcounter, so
701          that people may see what really happens, and what will
702          be available in the future :-)
703         
704    - 1.21alpha12 :
705

712   
713        - Now user and group print quota entries can be stored directly
714          below the user or group with the LDAP backend, using them
715          as branches. Thanks to Stefan Wold for the patch.
716          See the sample configuration file for details.
717         
718        - TLS is now supported with the LDAP backend. Thanks to Stefan
719          Wold for the patch.
720          See the sample configuration file for details.
721         
722        - edpkota now accepts the -U | --used value command line argument
723          to preset the page counters to an initial value. Thanks to
724          Wilson Roberto Afonso and Matt Hyclak for the patch.
725         
726    - 1.21alpha10 :
727   
728        - Now automatically reconnects up to three times if the LDAP server
729          returned an error, possibly due to a timeout.
730         
731    - 1.21alpha9 :
732   
733        - Now searches the configuration files in 'pykota' system user's
734          home directory. The 'pykota' system user and group have
735          to be created by the system administrator, and given
736          sufficient permissions to PyKota's configuration files.
737

787    - 1.20 :
788   
789        - Version number changed.

804       
805    - 1.20alpha27 :
806

808          the Brazilian Portuguese translation file was incorrectly
809          installed into the french "breton" locale directory.
810

861        - Now any PyKota administrator can use repykota and warnpykota
862          with additionnal arguments, not only the root user.
863

908         
909    - 1.20alpha15 :
910   
911        - LDAP pykotaAccountBalance objects were always created
912          attached to the pykotaUser objects. This is now
913          fixed and the value of balancebase in pykota.conf
914          is now correctly used.
915         
916    - 1.20alpha14 :
917

932          for this to work (tested with v3.4.2)
933         
934        - Increased delay between two loops iterations 
935          to 2 seconds in waitprinter.sh to diminish
936          CPU load.
937         
938    - 1.20alpha12 :

988         
989        - Minor fix in software accounter for a recently introduced
990          problem.
991         
992    - 1.20alpha4 :
993   
994        - Added support for more ghostscript devices in ESC/P2
995          analyzer : stcolor, st800, escp, escpc are now supported.
996         
997    - 1.20alpha3 :
998       
999        - Small improvement in PostScript parser to avoid being
1000          fooled by a change in number of copies :
1001          The user can't ask for 200 copies of page 1 and 1 copy
1002          of page 2 to fool PyKota anymore :
1003          this would have been accounted for as 1 copy only, but
1004          now the maximum value seen is used.
1005         
1006        - Relax checks for PCL5 header to accomodate some strange
1007          printer drivers.
1008         
1009        - Now hardware accounting method works like software
1010          accounting method wrt the subprocess' output.
1011         
1012        - Hardware and Software accounting stop the print queue 
1013          when the accounting subprocess didn't work. This will
1014          be configurable in the near future.
1015         
1016    - 1.20alpha2 :
1017   
1018        - Now software accounting method reads accounter's
1019          answer until a line with a single integer is
1020          obtained or until all of its output has been read.
1021          This should fix the problem some people have
1022          when strange locale related messages are sent
1023          when running subprocesses (Solaris only ?).
1024         
1025        - First version of ESC/P2 analyzer. Seems to work
1026          ok at least with 'epson', 'epsonc', 'eps9mid'
1027          and 'esp9high' ghostscript devices. Needs more
1028          work to correctly analyze other devices.
1029       
1030    - 1.20alpha1 :
1031   
1032        - Fixed problem with number of copies in PCLXL parser.
1033       
1034        - Fixed problem with number of copies in PCL5 parser,
1035          when number of copies was set outside of and before first
1036          page.
1037       
1038        - Added workaround for number of copies directly set in
1039          PostScript code.
1040         
1041        - Added german translation.
1042       
1043        - Fixed problem on first print for user group quota when
1044          "enforcement: strict" is used.
1045       
1046        - Fixed interpolation problem in french translation.
1047       
1048    - 1.19 :
1049   
1050        - Updated existing translations.   
1051       
1052        - Added final Thai and Greek translations.
1053       
1054        - Minor last minute bug fixes.
1055       
1056    - 1.19beta :
1057   
1058        - LPRng support for both software and hardware accounting seems
1059          to be OK.
1060         
1061        - Translation files fixed because of fuzzy matching problem. 
1062       
1063        - Fixed path to Swedish translation: 'sv' instead of 'se'.
1064       
1065        - Added first draft of Thai translation.
1066       
1067        - Fixed some minor bugs with Pychecker.
1068       
1069    - 1.19alpha35 :
1070   
1071        - Generic PDL analyzer now supports Binary PostScript documents
1072          in addition to DSC compliant ones.
1073       
1074    - 1.19alpha34 :
1075   
1076        - LPRng support : software accounting seems to work fine,
1077          but hardware accounting doesn't work yet.
1078   
1079    - 1.19alpha33 :
1080   
1081        - pykosd now accepts command line arguments. Enjoy !
1082          NB : due to a bug in xosd, you need xosd version 2.2.8
1083          or higher if you don't use the default C locale.
1084         
1085    - 1.19alpha32 :
1086   
1087        - Early (not working) version of the LPRng support rewrite.
1088       
1089        - Saner default configuration file.
1090       
1091    - 1.19alpha31 :
1092   
1093        - Fixed a double Python2.1 incompatibility with newer versions,
1094          which prevented the PCL5 and the PCLXL parsers to work with
1095          this older version of Python.
1096         
1097    - 1.19alpha30 :
1098   
1099        - Introduction of preliminary version of the pykosd command
1100       
1101        - Usernames, Groupnames and Printernames can now contain
1102          ANY character, expected '/' and '@'.
1103       
1104        - Integrated most of the Debian work from Sergio
1105          Gonz�z Gonz�z
1106         
1107    - 1.19alpha29 :
1108   
1109        - PCLXL parser should now correctly handle number of
1110          copies set for each page.
1111         
1112        - Added testsuite for generic PDL analyzer.
1113       
1114        - Typo fixed in PCLXL parser.
1115       
1116        - Correctly dispatches error messages depending on the
1117          situation : tools which can be run interactively will
1118          ALWAYS output their logs to stderr, excepted for
1119          their DEBUG messages, for which the "logger:"
1120          directive as set in pykota.conf will be honored.
1121          Tools which can't be run interactively will ALWAYS
1122          honor the "logger:" directive as set in pykota.conf
1123         
1124    - 1.19alpha28 :
1125   
1126        - The description field for printers can now be set,
1127          and is displayed in reports.
1128         
1129        - Fixed a small problem in SQL backend code.
1130         
1131        - Improved pkhint
1132       
1133        - First working PCL6 (aka PCLXL) parser !
1134          Doesn't handle copies yet.
1135       
1136    - 1.19alpha27 :
1137   
1138        - Additionnal 10% speed increase in PCL5 parser for GhostScript
1139          generated files (untested yet with other PCL files).
1140         
1141        - Reintroduced the use of mmap in PCL5 parser : this speedups
1142          PCL5 parsing by almost 4 times.
1143          This 4x with the 3x below give us in fact a twelvefold increase
1144          in performance for PCL5 parsing !
1145         
1146        - The Python accelerator Psyco is now used if available
1147          in the generic PDL parser : it speedups PCL5 parsing by
1148          almost three times automagically.
1149         
1150    - 1.19alpha26 :
1151   
1152        - Fixed PCL5 parser according to the sources of rastertohp.
1153       
1154        - Fixed number of copies handling in PCL5 parser : the number
1155          of copies could vary from page to page.
1156         
1157        - Added more debug information to PCLXL parser. 
1158       
1159    - 1.19alpha25 :
1160   
1161        - Added new "description" field to printers in both
1162          PostgreSQL and LDAP. No code to handle this yet.
1163         
1164        - Reversed the fix for power save mode in printers : 
1165          no paper or tray open would have caused people to
1166          be undercharged.
1167         
1168        - Preliminary version of MySQL initialization script.
1169         
1170    - 1.19alpha24 :
1171   
1172        - Native PDF parsing code now works perfectly with
1173          Python 2.1 and above, and is way faster than before.
1174          GhostScript is not used anymore to convert PDF to PS,
1175          because PDF is parsed directly.
1176         
1177    - 1.19alpha23 :
1178   
1179        - Fixed waitprinter.sh wrt PowerSave mode and some
1180          printers. Thanks to Ryan Suarez.
1181       
1182        - Smart PDL analyzer now recognizes PDF too : two
1183          PDF parsing methods are used : a native one which
1184          is very fast but requires Python 2.3 or above, and
1185          a slower one which uses Ghostscript. PyKota detects
1186          automatically which method to use depending on your
1187          version of Python.
1188       
1189        - All tracebacks now include PyKota's version number.
1190         
1191    - 1.19alpha22 :
1192   
1193        - Ensures that the file pointer for job's data is
1194          reset to the start of the job's datas after the
1195          job's size pre-computation phase.
1196         
1197        - Improved PostScript detection code for bad drivers
1198          which don't correctly switch languages between PJL
1199          and PS.
1200       
1201        - Even better debugging code.
1202       
1203    - 1.19alpha21 :
1204   
1205        - Additionnal check.
1206       
1207    - 1.19alpha20 :
1208   
1209        - More complete logging messages wrt accounters.
1210       
1211        - Now catches early failures occuring when the configuration
1212          files are parsed.
1213       
1214    - 1.19alpha19 :
1215   
1216        - Fixed over-verbose exits when displaying help
1217          or version.
1218         
1219        - Extended some PATH in the shell scripts 
1220       
1221        - Deleting an user now also deletes his payments history.
1222       
1223        - Doesn't explicitely ignore SIGCHLD anymore. This seems to
1224          cause problems.
1225
1226    - 1.19alpha18 :
1227   
1228        - History of payments is now stored in the database, and
1229          updated each time an user's balance is modified with
1230          edpykota --balance. This history represents each time
1231          the user was given some positive or negative credit,
1232          but doesn't reflect price paid for jobs, which appear
1233          in the jobs history instead.
1234         
1235        - Jobs history web reports now include the job's size in
1236          bytes. Also columns were reordered to render the report
1237          more easily readable.
1238         
1239    - 1.19alpha17 :
1240   
1241        - Mysterious bug (program exited unexpectedly without leaving
1242          any log message) which occured once in a while when
1243          cancelling jobs should be fixed now.
1244         
1245        - New 'crashrecipient' directive. Disabled by 
1246          default. See sample configuration file to see how
1247          to activate it. It is suggested that you activate it.
1248         
1249        - New PYKOTAJOBSIZEBYTES environment variable exported, 
1250          which contains the job's size in bytes. Empty jobs
1251          are now denied. This value is now stored in the job
1252          history (but not yet displayed from the web interface)
1253         
1254        - Preliminary work on payments storage : the PostgreSQL 
1255          and LDAP schemas should be OK now, but no code is written
1256          yet to support this functionnality.
1257         
1258    - 1.19alpha16 :
1259   
1260        - the newuser and newgroup LDAP specific directives now accept
1261          a second parameter to attach(), "fail" or "warn". If no entry
1262          is found to attach PyKota attributes to, and "fail" was used,
1263          then action is aborted and program exits in error. If "warn"
1264          is used, a new entry is created but a warning message is logged.
1265         
1266        - The job's originating hostname is now stored in the database,
1267          and exported as PYKOTAJOBORIGINATINGHOSTNAME in the environment.
1268       
1269    - 1.19alpha15 :
1270   
1271        - The old pykota filter is now removed. This means that
1272          currently PyKota doesn't support LPRng anymore, but
1273          LPRng support will be re-added, improved, in the near future.
1274         
1275    - 1.19alpha14 :
1276   
1277        - PYKOTAPRECOMPUTEDJOBSIZE and PYKOTAPRECOMPUTEDJOBPRICE
1278          are now exported as environment variables.
1279         
1280        - Heavy CPU usage is now completely fixed it seems, by
1281          introducing some 0.01 second sleeping when nothing to do.
1282         
1283        - Pre-computation of the job's size is now only
1284          done when enforcement is "STRICT", this saves
1285          CPU for people who don't want to use this new
1286          feature.
1287         
1288        - New 'enforcement' directive which accepts either
1289          STRICT or LAXIST. See sample configuration file
1290          for details.
1291         
1292    - 1.19alpha13 :
1293   
1294        - Get back to an old version of the polling loop which
1295          worked fine, but non-optimally. Will be optimized
1296          as time permits.
1297         
1298    - 1.19alpha12 :
1299   
1300        - Job's size is now precomputed unconditionnally using
1301          the generic PDL analyzer.
1302          NB : This value is not yet used to pre-allow/deny the
1303          job.
1304       
1305    - 1.19alpha11 :
1306   
1307        - The pykota filter is now completely deprecated and
1308          can't be used anymore. LPRng users MUST download
1309          an older version of PyKota. CUPS users MUST use
1310          cupspykota. Better support for LPRng will come
1311          in the near future.
1312         
1313    - 1.19alpha10 :
1314   
1315        - pykotme now uses generic PDL Analyzer directly instead
1316          of spawning a new process.
1317         
1318        - Improvements to generic PDL Analyzer.
1319       
1320        - 25% Speedup in PCL parser. Getting more of the Python version
1321          will probably be difficult, since the completely table driven
1322          parser I wrote is slower than the original algorithm. Then,
1323          the original algorithm is still used for now.
1324          Probable that more speed could be achieved using mmap, at the
1325          expense of severe memory consumption.
1326       
1327        - configuration simplifications : the "accounter" directive's
1328          'hardware' arguments now accepts what was in the "requester"
1329          directive as it's content. The "requester" directive is not
1330          supported anymore. See sample configuration file for details.
1331       
1332    - 1.19alpha9 :
1333       
1334        - pkpgcounter is now just a wrapper around the PDLAnalyzer class
1335       
1336        - pykotaOptions LDAP attribute now accepts non-ascii characters
1337          too.
1338         
1339        - First try at cupspykota main loop rewrite
1340       
1341    - 1.19alpha8 :
1342   
1343        - 'querying' accounting method is now called 'hardware'
1344       
1345        - 'external' accounting method is now called 'software'
1346       
1347        - 'stupid' accounting method doesn't exist anymore
1348       
1349        - 'snmp' requester doesn't exist anymore
1350       
1351        - code simplifications in external requester
1352       
1353    - 1.19alpha7 :
1354     
1355        - Database schema change (both LDAP and PostgreSQL) to
1356          allow storage of the job-originating-hostname attribute.
1357          An SQL upgrade script is present. The code is not yet
1358          capable of setting/retrieving this attribute. Support
1359          for this functionnality will be added in the future.
1360         
1361    - 1.19alpha6 :
1362   
1363        - problems connecting to SMTP servers are now catched.
1364       
1365        - pykotme now uses pkpgcounter to compute the size of the
1366          job. This modification adds PCL5 and soon PCLXL (PCL6)
1367          support. You can now get quotes for PCL in addition to
1368          PostScript.
1369         
1370        - pkpgcounter now includes first try at PCLXL parser. 
1371          It is currently disabled until it's finished.
1372         
1373    - 1.19alpha5 :
1374   
1375        - cupspykota polling loop fix for MacOSX (at least)
1376       
1377        - logging subsystem now logs PID too, to ease diagnosing
1378          problems under heavy load.
1379         
1380        - pkpgcounter enhancements.
1381       
1382        - pkprinters --skipexisting now tells pkprinters to not
1383          modify existing printers when --add is used.
1384          pkprinters logs a warning message whenever --add is
1385          used and a printer already exists.
1386         
1387        - LDAP schema now allows accented chars in pykotaFileName
1388          and pykotaTitle attributes.
1389       
1390    - 1.19alpha4 :
1391   
1392        - a bad copy&paste prevented pkpgcounter to work at all, this
1393          is now fixed.
1394         
1395        - improved PCL support in pkpgcounter, with the use of
1396          HP PCL/PJL Reference Set
1397          PCL5 Printer Language Technical Quick Reference Guide
1398       
1399        - pkpgcounter now uses mmap to speed things up : duration
1400          is halved with the sample 87 pages PCL document I use for
1401          testing.
1402         
1403    - 1.19alpha3 :
1404   
1405        - pkprinters now accepts the --list command line argument
1406          to list informations about printers.
1407         
1408    - 1.19alpha2 :
1409   
1410        - pkpgcounter is now included as a smart external
1411          accounter which can handle both PostScript and PCL.
1412         
1413    - 1.19alpha1 :
1414   
1415        - PYKOTALIMITBY environment variable is now exported too.
1416       
1417        - Inclusion of Michele Baldessari's work on autotools.
1418       
1419    - 1.18 :
1420   
1421        - Improved documentation
1422       
1423    - 1.18beta2 :
1424     
1425        - Fix for raw jobs with cupspykota
1426       
1427    - 1.18beta :
1428   
1429        - Small fix for new waitprinter.sh script
1430       
1431        - Better tracebacks on error conditions
1432       
1433        - Improved translations
1434       
1435        - Improved documentation
1436       
1437    - 1.18alpha15 :
1438
1439        - waitprinter.sh replaced by a new and possibly faster
1440          and more powerful one.
1441   
1442        - Names can now begin with a digit.
1443       
1444        - Stability improvement for quotas set on printers groups.
1445       
1446    - 1.18alpha14 :
1447   
1448        - Catches more (all ?) problems with SMTP servers instead
1449          of breaking.
1450         
1451        - Italian translation added.
1452       
1453    - 1.18alpha13 :
1454   
1455        - Pre and Post hooks are now available in the pykota
1456          filter as well.
1457         
1458        - The pykota filter doesn't check last user's quota
1459          anymore when delayed hardware accounting is used :
1460          this will be done anyway the next time the last
1461          user will print again. This saves some database
1462          queries which are unneeded.
1463       
1464    - 1.18alpha12 :
1465   
1466        - Pre and Post hooks to external commands with many
1467          many environment variables available are useable
1468          from the cupspykota backend.
1469          See sample configuration file for details and help.
1470         
1471    - 1.18alpha11 :

1480       
1481    - 1.18alpha9 :
1482   
1483        - Fix for LDAP problem when job price was 0.
1484       
1485        - Fix for empty user groups with LDAP.
1486       
1487        - Preliminary version of the snmpprinterstatus command added.
1488       
1489    - 1.18alpha8 :
1490   
1491        - Don't retrieve data when not needed.

1493       
1494    - 1.18alpha7 :
1495   
1496        - New experimental ldapcache directive to improve
1497          LDAP caching.

1507    - 1.18alpha5 :
1508   
1509        - Debian packaging specific files, contributed by
1510          Peter Hawkins are now included in the project's tree.
1511         
1512        - Preliminary work on future low-level LDAP caching to speed
1513          up modifications (at least).
1514         
1515    - 1.18alpha4 :
1516   
1517        - Applied some of the modifications suggested by
1518          Peter Hawkins, for better Debian integration.
1519          Most notably cupspykota, pykota, and the shell
1520          scripts are now installed into /usr/share/pykota
1521          instead of into /usr/bin
1522          BEWARE : double check that your symbolic link
1523          to cupspykota is correct, and that your pykota.conf
1524          file use correct path for the shell scripts like
1525          waitprinter.sh and al.
1526         
1527        - pkhint command added, to help in configuring correct
1528          accounting method for PyKota.

1564          added to the documentation. Doesn't yet document v1.16
1565          though.
1566       
1567        - Portuguese Portuguese translation replaces Brazilian
1568          Portuguese Translation. Brazilian portuguese
1569          translation is still available under the 'br' locale.
1570       
1571    - 1.16beta3 :
1572

1576       
1577    - 1.16beta2 :
1578   
1579        - Small fix for job cancelling code while job already
1580          printing in CUPS backend.
1581         
1582        - Big fix wrt printing policies for unknown users. 
1583       
1584    - 1.16beta1 :
1585   
1586        - Manpages upgraded.
1587       
1588    - 1.16alpha26 :
1589   
1590        - Job price is now computed like this :
1591       
1592          SUM((NbPages * PricePerPage) + PricePerJob)
1593         
1594          For current printer and all the printers groups it is
1595          a member of, if any.
1596         
1597          This may be difficult to grasp, but offers unprecedented
1598          flexibility.
1599         
1600    - 1.16alpha25 :
1601   
1602        - Email address can be set at user creation time,

1614          automatically add printers on first print.
1615       
1616    - 1.16alpha23 :
1617   
1618        - Fixed potential accuracy problem if a user printed on
1619          several printers at the very same time.
1620

1638       
1639    - 1.16alpha18 :
1640   
1641        - Initial code for printer groups support. Printer groups have
1642          to be added with external tools like psql or gq for example.
1643          Printer groups seems to work fine with users. Untested with user
1644          groups for now.
1645
1646        - Several minor visual problems fixed in reports.
1647       
1648        - Fixed a bug in LDAP date handling.
1649       
1650        - Fix for LDAP problem with some combination of OpenLDAP + Python-LDAP
1651          + some particular settings.

1653        - mailandpopup.sh shell script added. See sample configuration file
1654          for details.
1655       
1656        - Several environment variables are now exported when executing
1657          external commands (accounters, requesters, mailers) :
1658           
1659            PYKOTAUSERNAME => user who is printing
1660            PYKOTAPRINTERNAME => printer on which the job is being sent
1661            PYKOTATITLE => Job's title
1662            PYKOTAFILENAME => Job's filename
1663            PYKOTACOPIES => number of copies asked
1664            PYKOTAOPTIONS => print command options (-o with CUPS)
1665         
1666    - 1.16alpha17 :
1667   
1668        - Added portugues translation.
1669       
1670        - Major code refactoring in accounters.
1671       
1672    - 1.16alpha16 :
1673   
1674        - Code refactoring, and addition of a real HTML reporter, to
1675          have nice looking and useful web based reports (in the future).
1676       
1677        - Added utolower configuration option to convert all usernames
1678          to lowercase during printing.

1682        - Now includes the papwaitprinter.sh shell script to wait for
1683          AppleTalk enabled printers.
1684         
1685    - 1.16alpha14 :
1686   
1687        - Now printing on a printer not defined in the Quota Storage,
1688          results in the job being cancelled or stopped, depending
1689          on the printing system.
1690         
1691    - 1.16alpha13 :
1692   
1693        - Small bugfix wrt Python v2.1
1694       
1695        - If username is an empty string, user root is assumed.
1696       
1697        - 'postgresql' is not recognized anymore as a storage backend,
1698          you have to use 'pgstorage' instead. 'postgresql' used to
1699          be supported for compatibility with very old PyKota versions,
1700          this is not the case anymore.
1701         
1702    - 1.16alpha12 :
1703   
1704        - Job price added to job history, to keep accounting correct
1705          if a printer price per page or per job is modified and the
1706          history is not reset : the history would have given a false
1707          amount of money charged before the printer's prices were
1708          modified, this addition solves the problem.
1709         
1710    - 1.16alpha11 :
1711   
1712        - Some preliminary modifications to the database structure for
1713          PostgreSQL and OpenLDAP. A script to upgrade a PostgreSQL
1714          database is now provided. LDAP attributes now support
1715          eq, pres and sub indexes.
1716         
1717        - Job history now contains additional informations : 
1718          number of copies, filename, title and print options.
1719         
1720    - 1.16alpha10 :
1721       
1722        - Some modifications done to external policy handling.
1723          See sample configuration file for details.
1724   
1725        - Spanish translation added.
1726       
1727    - 1.16alpha9 :
1728   
1729        - mailto can be set to external(...) to warn users above
1730          quota with any command of your choice (e.g. linpopup).
1731          Several parameters are available, see sample configuration
1732          file for details.
1733         
1734    - 1.16alpha8 :
1735   
1736        - Now cupspykota transmits SIGTERMS to the original 
1737          backend when the user deletes a job being processed.
1738         
1739        - The documentation is now licensed under the terms of the
1740          GNU GPL too.
1741         
1742    - 1.16alpha7 :
1743   
1744        - The CUPS backend is now fully functionnal (it seems).
1745       
1746        - From now on, the use of the pykota filter with CUPS
1747          is deprecated. The pykota filter still has to be
1748          used with LPRng though.
1749       
1750    - 1.16alpha6 :
1751   
1752        - Bug fixed : when edpykota was used to add a printer
1753          with no user or group name, a bad user/group name "*" was
1754          added to the database.
1755         
1756    - 1.16alpha5 :
1757   
1758        - New CUPS backend supports device enumeration !
1759          This means that NO manual CUPS configuration has to
1760          be done. All can now be done from CUPS web interface.
1761       
1762    - 1.16alpha4 :
1763   
1764        - New CUPS backend added.
1765       
1766    - 1.16alpha3 :
1767       
1768        - Minimal FAQ document added.

1777       
1778        - More complete error messages in case of LDAP operation failure.
1779       
1780    - 1.15 :
1781     
1782        - Documentation improved.
1783       
1784    - 1.15beta :
1785   
1786        - Command line tools now accept multiple printer
1787          names or wildcards, separated with commas.
1788         
1789    - 1.15alpha9 :
1790   
1791        - External policy can be used to auto-add unknown users
1792          and any other interesting things you may want to do.
1793          WARNING : You can't auto-add printers for now.
1794          They have to be created manually before.
1795          Look at sample configuration file for examples.
1796         
1797    - 1.15alpha8 :
1798   
1799        - Job history can be disabled if needed.
1800          This feature may be useful for people who use the LDAP
1801          backend and don't want their LDAP tree to grow out of
1802          control.
1803       
1804    - 1.15alpha7 :
1805   
1806        - More work done on caching wrt groups.
1807

1814        - Caching mechanism for all database queries.
1815
1816    - 1.15alpha4 :
1817   
1818        - Problem with Python 2.3 fixed. Needs some definitive
1819          modification.
1820         
1821    - 1.15alpha3 :
1822   
1823        - CGI script now tries to restrict view when the
1824          REMOTE_USER environment variable is set. This allows
1825          people to protect its use with .htaccess files.
1826          When unprotected, or if REMOTE_USER is 'root', then
1827          unrestricted access is granted.
1828          NB : REMOTE_USER is automatically set by the web server
1829          (e.g. Apache) when a page with restricted access is viewed.
1830         
1831    - 1.15alpha2 :
1832   
1833        - Better detection of LPRng.
1834       
1835        - Outputs a warning if printing system is unknown.
1836       
1837    - 1.15alpha1 :
1838   
1839        - Bug fix in SQL code.
1840       
1841    - 1.14 :
1842   
1843        - The PostgreSQL database connection is now always closed before
1844          exit. The LDAP database connection too, but it didn't suffer
1845          from the problem anyway, AFAICT.
1846       
1847    - 1.14beta2 :
1848   
1849        - An LDAP-specific configuration field was introduced, usermail.
1850          Use it to specify which LDAP attribute contains a valid email
1851          address for the user. See sample configuration file for
1852          details.
1853       
1854    - 1.14beta :
1855   
1856        - Two new LDAP-specific configuration fields were introduced,
1857          newuser and newgroup. Use them to specify if you want to add
1858          quota information to existing entries or elsewhere.
1859          See sample configuration file for details.
1860         
1861    - 1.14alpha9 :
1862   
1863        - Documentation improved.
1864       
1865        - pykotme now also prints the user's account balance value
1866          if the user is registered in the Quota Storage and his
1867          limiting factor is "balance".
1868         
1869    - 1.14alpha8 :
1870   
1871        - bin/waitprinter.sh is now included to wait for
1872          SNMP enabled printers to be idle again before
1873          asking for their internal page counter.
1874          See sample configuration file for details.
1875         
1876    - 1.14alpha7 :
1877   
1878        - edpykota now doesn't check if the user/group is above
1879          quota. The check is only done at print time. This
1880          prevents the sending of email messages when creating
1881          user quotas if quota is already reached at creation
1882          time.
1883         
1884    - 1.14alpha6 :
1885   
1886        - Configuration file split and moved to /etc/pykota/pykota.conf
1887          and /etc/pykota/pykotadmin.conf to prevent simple users to
1888          have Read/Write access to the Quota Database.
1889          Don't forget to :
1890         
1891                $ chmod 640 /etc/pykota/pykotadmin.conf
1892               
1893        - storageuser and storageuserpw configuration fields reintroduced
1894          for the same reason.
1895         
1896        - Code cleaning for future implementation of email addresses
1897          support in the PostgreSQL and LDAP backends.
1898         
1899    - 1.14alpha5 :
1900       
1901        - Big bug fixed when changing the prices for a printer
1902       
1903    - 1.14alpha4 :
1904   
1905        - When adding an user, the user itself and its account balance
1906          are now added in the same LDAP entry. Before they were added
1907          as two different LDAP entries.
1908         
1909    - 1.14alpha3 :
1910   
1911        - Email field added to PostgreSQL database. An upgrade script
1912          is included in initscripts/postgresql.

1921          balance (below 1.0 by default, configurable) are sent
1922          a warning message.
1923         
1924        - All warning messages to users are now configurable. 
1925          NB : Warning messages to the administrator are not.
1926       
1927    - 1.13 :
1928   
1929        - Some small fixes wrt group handling.
1930       
1931        - The whole module code was passed through PyChecker and
1932          several small code inconsistencies were fixed,
1933          as well as a bug in the groups code.
1934         
1935    - 1.13alpha1 :
1936   
1937        - Bug fix wrt LDAP.
1938       
1939    - 1.12 :
1940

1988        - repykota and warnpykota only reports or warns the
1989          current user when launched by non-root users.
1990         
1991        - Minor bug fixes. 
1992   
1993    - 1.09alpha1 :
1994   
1995        - More work on LDAP storage backend. Many options
1996          were added to /etc/pykota.conf to give some
1997          hints to the LDAP storage backend.
1998         
1999        - Severe database access optimizations were done by

2010        - Code refactoring.
2011       
2012        - A single user/password pair is used to connect

2015          not used anymore.
2016         
2017        - You can now set PyKota in debug mode, see sample configuration 
2018          file for details.
2019          WARNING : only Quota Storage backend queries are logged in
2020          debug mode, for now.
2021       
2022    - 1.08alpha7 :
2023   
2024        - Very latest LDAP schema.
2025       
2026        - Code enhancement wrt easy pluggability of PyKota attributes
2027          and object classes into an existing LDAP directory.
2028       
2029    - 1.08alpha6 :
2030   
2031        - Minor bug corrections
2032       
2033        - More work on LDAP : new schema
2034       
2035    - 1.08alpha5 :

2038          repykota now works reasonably well with the sample LDAP directory.
2039       
2040    - 1.08alpha4 :
2041   
2042        - LDAP schema included.
2043          THIS IS JUST FOR PEOPLE TO DISCUSS ABOUT THIS.
2044          LDAP SUPPORT DOESN'T WORK YET, AND THE SCHEMA
2045          MAY CHANGE IN THE FUTURE. PLEASE TELL US
2046          WHAT YOU THINK ABOUT THIS SCHEMA ON THE
2047          MAILING LIST.
2048         
2049    - 1.08alpha3 :
2050   
2051        - External accounting methods were partly rewritten :
2052         
2053          - No more "broken pipe" should happen.
2054         
2055          - They now take care of the number of copies
2056            This may be unneeded though, if the postscript
2057            file already does this, because this would
2058            overcharge users (number of copies counted
2059            two times). NEEDS MORE TESTING.
2060           
2061          - The sample configuration file now contains 
2062            an external accounting method example which should
2063            work with all DSC compliant Postscript files.
2064           
2065        - Some small bugs were fixed.   
2066       
2067    - 1.08alpha2 :
2068   
2069        - Now works with net-snmp v5.0 and above.
2070          It already worked, but the sample configuration
2071          file didn't contain appropriate values...
2072       
2073    - 1.07 : Release of the Shame !
2074   
2075        - The external accounting methods driver was left out of
2076          the CVS tree. Nobody could use it since it wasn't included !
2077         
2078    - 1.06 :
2079   
2080        - Severe bug fixed : if you had a printer in
2081          power saving state which couldn't answer immediately,
2082          a bug was triggered.
2083          It was caused by a bad copy/paste which
2084          forgot to import a Python module at run time.
2085         
2086    - 1.05 :
2087   
2088        - External accounters are finally available !
2089          This means that you can plug any page accounting
2090          method you like by setting the appropriate
2091          'accounter' field in /etc/pykota.conf
2092          See the sample conf/pykota.conf.sample to
2093          learn how to do.
2094         
2095          NB : Both 'external' and 'stupid' accounting methods
2096               account a job size just before *this* job is
2097               sent to the printer.
2098               The original 'querying' method accounts a job
2099               size just before *the next* job is sent to
2100               the printer.
2101       
2102    - 1.05alpha3 :
2103   
2104        - A 'stupid' and unreliable accounting method was
2105          implemented to serve as an example on how to
2106          do this sort of things. This method only counts
2107          the 'showpage' statements in the input data.
2108          See sample configuration file for details.
2109          Pluggable accounting methods work, but I advise
2110          you TO NOT USE THIS ONE WHICH IS JUST AN EXAMPLE.
2111          It is not reliable enough to be used.
2112          Use the 'querying' accounting method instead.
2113         
2114    - 1.05alpha2 :
2115   
2116        - Pluggable accounting methods.
2117       
2118        - Better error handling.
2119       
2120    - 1.05alpha1 :
2121   
2122        - SECURITY file added to help improve PyKota's security.
2123       
2124        - Extracting the printer's internal page counter is now
2125          tried several times, waiting several seconds between
2126          two tries. This lets the time to warm up for some printers
2127          which don't answer when they are sleeping (my Apple
2128          LaserWriter 16/600 PS is in this case, maybe others too)
2129         
2130        - Small display bug fixed in repykota
2131         
2132    - 1.04 :
2133   
2134        - Default print policy for users/groups unknown from
2135          the print quota system is now DENY instead of ALLOW,
2136          since ALLOW can generate inaccurate results
2137          (incorrect job sizes charged to the wrong persons)
2138         
2139        - LPRng support works !
2140       
2141        - A bug was introduced some time ago wrt printers' default
2142          policy for unknown users. It is now corrected.
2143       
2144        - repykota now displays prices per job and per page for each
2145          printer, if they are defined.
2146         
2147        - Minor display bug fixed in repykota.
2148       
2149        - Problem when running repykota with an empty database was fixed.
2150       
2151    - 1.03 :
2152   
2153        - Upgrade script included for earlier versions.
2154          Please look inside the initscripts subdirectory.
2155          THE DATABASE SCHEMA HAS CHANGED, PLEASE UPGRADE.
2156         
2157        - repykota now reports account balances too.
2158       
2159        - PyKota now has a nice logo, see the logos
2160          subdirectory.
2161       
2162        - Manual pages were finally updated.
2163       
2164        - Group quotas seem to work now !
2165       
2166        - The new database schema allows to keep an history of all
2167          jobs as well as charge users per page and/or per job,
2168          and track users' account balance.
2169         
2170        - edpykota now accepts much more command line options to 
2171          use the new functionnalities. See edpykota --help for
2172          details.
2173         
2174        - The installation script now allows to install the sample
2175          configuration file during first installation.
2176         
2177        - More group quota code works, but still not finished. 
2178       
2179        - The CGI script displays a link to PyKota's website.
2180       
2181        - The job history is now kept, this will allow per-period
2182          reports in the future.
2183         
2184        - After having modified the quota for an user with edpykota,
2185          a quota check is done to eventually warn the user/admin about
2186          a quota which is too low to print.
2187         
2188        - A workaround is provided for HP Printers : their internal
2189          page counter is only saved to NVRAM in a 10 increment, so
2190          if you switch them off and then on, the reported page counter
2191          may be lower than the real number of pages printed.
2192          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
2193          We unconditionnally set the last job's page count to
2194          abs(int((10 - abs(lastcounter(snmp) - lastcounter(storage)) / 2))
2195          in this case.
2196          For a more accurate accounting, never switch your HP printers
2197          off.
2198         
2199        - A fix is provided for printers which only have a volatile 
2200          page counter (reset to 0 every time you switch the printer on)
2201          This should allow PyKota to work reasonably fine with HP Laserjet
2202          4L/5L/6L, not perfect, but better than nothing.
2203          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
2204          For a more accurate accounting, never switch your HP printers
2205          off. This is untested, please report any problem.
2206         
2207        - A bug was fixed when edpykota --add was used with users who already
2208          had a quota on the specified printer.
2209         
2210        - A small display bug in repykota was introduced in preliminary
2211          1.03 versions, and fixed later on.
2212         
2213        - Some minor bugs which happened in rare situations were fixed.
2214       
2215        - Support for AppleTalk printers was added, see sample configuration
2216          file for details.
2217         
2218        - Users and group printing can now be controlled (limited) either by 
2219          print quota or by account balance.
2220       
2221    - 1.02 :
2222   
2223        - The installation script now checks for software availability
2224          and in case a software is missing asks the user if he
2225          wants to continue with the installation or abort it.
2226         
2227        - The configuration file pykota.conf is now expected to be
2228          found in /etc instead of in /etc/cups
2229          The installation script prompts the user to see if he
2230          wants to move an old configuration file to the new location
2231          if needed.
2232         
2233        - Improved documentation.
2234       
2235        - You can now set the tcp/ip port on which the Quota Storage
2236          Server is listening, see sample configuration file for details.
2237       
2238        - Better general error handling.
2239       
2240        - Upgrade script for pre 1.01 PostgreSQL database schema is now
2241          included as well.
2242       
2243    - 1.01 :
2244   
2245        - The configuration file now accepts an option   
2246          to choose the recipient(s) of the email messages :
2247         
2248            - DevNull means no one will receive them.
2249            - User means only the user will receive them.
2250            - Admin means only the admin will receive them.
2251            - Both means the User and the Admin will receive them.
2252           
2253        - The configuration file now uses hard-coded default values
2254          when an option is not set. See sample configuration file
2255          for details.
2256         
2257        - Manual pages are included since 1.00, but I forgot to   
2258          add this information to this file.
2259         
2260        - Redistribution terms for the official package have 
2261          softened and are now fully GPL compatible :
2262          unrestricted modification is now allowed even for
2263          the version number.
2264         
2265    - 1.00 :
2266   
2267        - edpykota now accepts a --noquota option. This
2268          disable quota checking while still doing page
2269          accounting. This is really useful for people
2270          who don't want to limit their users but want
2271          to know how much pages they print.
2272         
2273        - Some untested scripts were added to retrieve
2274          the life time page counter of non-SNMP printers.
2275         
2276        - Every directory now has a specific README file. 
2277       
2278    - 0.99 :
2279   
2280        - Under some circumstances while the user wasn't allowed
2281          to print, he didn't receive any email message. It is
2282          now fixed.
2283         
2284        - When an user wasn't allowed to print, the quota for
2285          the previous user wasn't updated. This is now fixed.
2286         
2287    - 0.98 :
2288   
2289        - Correctly handle the case where the printer is switched off.
2290       
2291        - Small bug wrt syslog fixed.
2292       
2293    - 0.97 :
2294   
2295        - edpykota accepts wildcards on its command line for users/groups too
2296          if the --add option is not set, e.g. :
2297         
2298              $ edpykota --printer lp --softlimit 50 --hardlimit 100 "jer*"
2299             
2300        - If no user name is passed at all, then a default wildcard of "*"
2301          which means apply the command on ALL users for this printer is used.
2302         
2303        - Small bug fixes.
2304       
2305    - 0.96 :
2306
2307        - Options requester, policy, admin, adminmail and gracedelay can now
2308          be set either globally or per printer. The printer option has
2309          priority if both are defined.
2310
2311        - More powerful configuration parser.
2312       
2313        - If all options are defined globally, there's no need to
2314          define a section for each printer in the configuration
2315          file anymore. Just define a [global] section and it's ok.
2316
2317    - 0.95 :
2318
2319        - External requesters for printers finally added.
2320
2321        - Full internationalization (english and french are supported)
2322 
2323        - More complete quota usage report
2324
2325        - CGI script to access to the quota usage report
2326
2327        - Several bugs fixed.
2328
2329
2330    - 0.9 :
2331
2332        - First public version
