22PyKota NEWS :
23
24    - 1.06 :
25   
26        - Severe bug fixed : if you had a printer in
27          power saving state which couldn't answer immediately,
28          a bug was triggered.
29          It was caused by a bad copy/paste which
30          forgot to import a Python module at run time.
31         
32    - 1.05 :
33   
34        - External accounters are finally available !
35          This means that you can plug any page accounting
36          method you like by setting the appropriate
37          'accounter' field in /etc/pykota.conf
38          See the sample conf/pykota.conf.sample to
39          learn how to do.
40         
41          NB : Both 'external' and 'stupid' accounting methods
42               account a job size just before *this* job is
43               sent to the printer.
44               The original 'querying' method accounts a job
45               size just before *the next* job is sent to
46               the printer.
47       
48    - 1.05alpha3 :
49   
50        - A 'stupid' and unreliable accounting method was
51          implemented to serve as an example on how to
52          do this sort of things. This method only counts
53          the 'showpage' statements in the input data.
54          See sample configuration file for details.
55          Pluggable accounting methods work, but I advise
56          you TO NOT USE THIS ONE WHICH IS JUST AN EXAMPLE.
57          It is not reliable enough to be used.
58          Use the 'querying' accounting method instead.
59         
60    - 1.05alpha2 :
61   
62        - Pluggable accounting methods.
63       
64        - Better error handling.
65       
66    - 1.05alpha1 :
67   
68        - SECURITY file added to help improve PyKota's security.
69       
70        - Extracting the printer's internal page counter is now
71          tried several times, waiting several seconds between
72          two tries. This lets the time to warm up for some printers
73          which don't answer when they are sleeping (my Apple
74          LaserWriter 16/600 PS is in this case, maybe others too)
75         
76        - Small display bug fixed in repykota
77         
78    - 1.04 :
79   
80        - Default print policy for users/groups unknown from
81          the print quota system is now DENY instead of ALLOW,
82          since ALLOW can generate inaccurate results
83          (incorrect job sizes charged to the wrong persons)
84         
85        - LPRng support works !
86       
87        - A bug was introduced some time ago wrt printers' default
88          policy for unknown users. It is now corrected.
89       
90        - repykota now displays prices per job and per page for each
91          printer, if they are defined.
92         
93        - Minor display bug fixed in repykota.
94       
95        - Problem when running repykota with an empty database was fixed.
96       
97    - 1.03 :
98   
99        - Upgrade script included for earlier versions.
100          Please look inside the initscripts subdirectory.
101          THE DATABASE SCHEMA HAS CHANGED, PLEASE UPGRADE.
102         
103        - repykota now reports account balances too.
104       
105        - PyKota now has a nice logo, see the logos
106          subdirectory.
107       
108        - Manual pages were finally updated.
109       
110        - Group quotas seem to work now !
111       
112        - The new database schema allows to keep an history of all
113          jobs as well as charge users per page and/or per job,
114          and track users' account balance.
115         
116        - edpykota now accepts much more command line options to 
117          use the new functionnalities. See edpykota --help for
118          details.
119         
120        - The installation script now allows to install the sample
121          configuration file during first installation.
122         
123        - More group quota code works, but still not finished. 
124       
125        - The CGI script displays a link to PyKota's website.
126       
127        - The job history is now kept, this will allow per-period
128          reports in the future.
129         
130        - After having modified the quota for an user with edpykota,
131          a quota check is done to eventually warn the user/admin about
132          a quota which is too low to print.
133         
134        - A workaround is provided for HP Printers : their internal
135          page counter is only saved to NVRAM in a 10 increment, so
136          if you switch them off and then on, the reported page counter
137          may be lower than the real number of pages printed.
138          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
139          We unconditionnally set the last job's page count to
140          abs(int((10 - abs(lastcounter(snmp) - lastcounter(storage)) / 2))
141          in this case.
142          For a more accurate accounting, never switch your HP printers
143          off.
144         
145        - A fix is provided for printers which only have a volatile 
146          page counter (reset to 0 every time you switch the printer on)
147          This should allow PyKota to work reasonably fine with HP Laserjet
148          4L/5L/6L, not perfect, but better than nothing.
149          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
150          For a more accurate accounting, never switch your HP printers
151          off. This is untested, please report any problem.
152         
153        - A bug was fixed when edpykota --add was used with users who already
154          had a quota on the specified printer.
155         
156        - A small display bug in repykota was introduced in preliminary
157          1.03 versions, and fixed later on.
158         
159        - Some minor bugs which happened in rare situations were fixed.
160       
161        - Support for AppleTalk printers was added, see sample configuration
162          file for details.
163         
164        - Users and group printing can now be controlled (limited) either by 
165          print quota or by account balance.
166       
167    - 1.02 :
168   
169        - The installation script now checks for software availability
170          and in case a software is missing asks the user if he
171          wants to continue with the installation or abort it.
172         
173        - The configuration file pykota.conf is now expected to be
174          found in /etc instead of in /etc/cups
175          The installation script prompts the user to see if he
176          wants to move an old configuration file to the new location
177          if needed.
178         
179        - Improved documentation.
180       
181        - You can now set the tcp/ip port on which the Quota Storage
182          Server is listening, see sample configuration file for details.
183       
184        - Better general error handling.
185       
186        - Upgrade script for pre 1.01 PostgreSQL database schema is now
187          included as well.
188       
189    - 1.01 :
190   
191        - The configuration file now accepts an option   
192          to choose the recipient(s) of the email messages :
193         
194            - DevNull means no one will receive them.
195            - User means only the user will receive them.
196            - Admin means only the admin will receive them.
197            - Both means the User and the Admin will receive them.
198           
199        - The configuration file now uses hard-coded default values
200          when an option is not set. See sample configuration file
201          for details.
202         
203        - Manual pages are included since 1.00, but I forgot to   
204          add this information to this file.
205         
206        - Redistribution terms for the official package have 
207          softened and are now fully GPL compatible :
208          unrestricted modification is now allowed even for
209          the version number.
210         
211    - 1.00 :
212   
213        - edpykota now accepts a --noquota option. This
214          disable quota checking while still doing page
215          accounting. This is really useful for people
216          who don't want to limit their users but want
217          to know how much pages they print.
218         
219        - Some untested scripts were added to retrieve
220          the life time page counter of non-SNMP printers.
221         
222        - Every directory now has a specific README file. 
223       
224    - 0.99 :
225   
226        - Under some circumstances while the user wasn't allowed
227          to print, he didn't receive any email message. It is
228          now fixed.
229         
230        - When an user wasn't allowed to print, the quota for
231          the previous user wasn't updated. This is now fixed.
232         
233    - 0.98 :
234   
235        - Correctly handle the case where the printer is switched off.
236       
237        - Small bug wrt syslog fixed.
238       
239    - 0.97 :
240   
241        - edpykota accepts wildcards on its command line for users/groups too
242          if the --add option is not set, e.g. :
243         
244              $ edpykota --printer lp --softlimit 50 --hardlimit 100 "jer*"
245             
246        - If no user name is passed at all, then a default wildcard of "*"
247          which means apply the command on ALL users for this printer is used.
248         
249        - Small bug fixes.
250       
251    - 0.96 :
252
253        - Options requester, policy, admin, adminmail and gracedelay can now
254          be set either globally or per printer. The printer option has
255          priority if both are defined.
256
257        - More powerful configuration parser.
258       
259        - If all options are defined globally, there's no need to
260          define a section for each printer in the configuration
261          file anymore. Just define a [global] section and it's ok.
262
263    - 0.95 :
264
265        - External requesters for printers finally added.
266
267        - Full internationalization (english and french are supported)
268 
269        - More complete quota usage report
270
271        - CGI script to access to the quota usage report
272
273        - Several bugs fixed.
274
275
276    - 0.9 :
277
278        - First public version
