CHANGES.txt - 2009-05-14 ------------------------ CHANGES IN CUPS V1.4b3 - Documentation fixes (STR #3044, STR #3057, STR #3153) - Added complete localizations for German, Japanese, Polish, and Russian and partial localizations for Chinese, Danish, Finnish, French, Italian, Korean, Norwegian, Portuguese, and Swedish (STR #3096, STR #3098, STR #3109, STR #3111, STR #3141) - The scheduler could crash when deleting an attribute (STR #3197) - The cups-driverd program did not detect symlink loops (STR #3185) - The EPSON 24-pin series driver should now feed the correct amount (STR #2624) - The scheduler now automatically logs the last N debug messages for failed print jobs. - You can now modify a raw print queue (STR #3133) - Fixed a number of ppdi issues and added a unit test to validate that ppdc + ppdi can generate and import the same data (STR #3152) - Moving jobs in the web interface now shows an error if you only have one printer or class added (STR #3094) - Since classes have never truly supported the printer-error-policy stuff added in CUPS 1.2, update the code to reflect the current reality and support only the retry-current-job policy for now (STR #3171) - Revised the password callback support (STR #2953) - ppdEmit*() did not choose between PageSize and PageRegion properly. - Make some fairly substantial changes to the Kerberos support code so that CUPS can work in multi-realm environments and does not require delegatable credentials. Shared printing still requires delegation, however "delegation by policy" can be enabled in the KDC to make this all work. - "AccessLogLevel actions" did not hide client-error-not-found errors. - AP_FIRST_InputSlot did not work with number-up. - cupsBackChannelRead() and cupsBackChannelWrite() could fail due to a lack of kernel buffers. - The IPP and LPD backends did not respond to side-channel requests while copying print data to a temporary file. - cupsWriteRequestData() flushed the output buffer unnecessarily, causing reduced performance in some situations. - If a CGI process died before sending its MIME headers, the request would hang on the client. - The printer/class/job search feature on the web interface did not work (STR #3132) - The scheduler did not write the printers out for classes. - CUPS-Get-PPDs did not work properly when filtering by language, product, or psversion (STR #3136) -

The cupstestppd program did not validate the PageSize and PageRegion values. - The cups-deviced helper program could miss reporting some backend devices (STR #3108) - The cupsSideChannelSNMP* functions did not work. - The scheduler could consume 100% CPU when jobs were canceled. - Clicking on "Select Another Make/Manufacturer" in the web interface incorrectly added the printer (STR #3095) - The scheduler no longer uses programs with insecure file permissions. - httpAssembleURI*() did not escape backslashes in hostnames. - The dnssd backend did not unquote "full names" before creating the device URI. - The scheduler now supports JobRetryInterval values less than 10 seconds. - Updated the Spanish localization (STR #3090) - The scheduler did not redo Bonjour/DNS-SD registrations when updating them failed. - The "authenticated" policy incorrectly required authentication for status operations. - ppdOpen*() incorrectly loaded PPDs with multiple JobPatchFile keywords. - The network backends no longer report the SNMP "offline" or maintenance status bits since they are inconsistently implemented and often unreliable. - The scheduler no longer logs child processes killed via SIGKILL as "crashed". - The printer link shown on the "job moved" template was bad (STR #3085) - Updated the HTML templates to use the final HTML 4 DOCTYPE (STR #3086) -

cupsGetNamedDest() did not use the fallback default like cupsGetDests*() (STR #3082) - The scheduler now provides a LogTimeFormat directive to enable microseconds in the date and time that are logged. - The scheduler now provides a MultipleOperationTimeout directive to control the timeout for multi-file print jobs. - The configure script incorrectly allowed Avahi to be used for DNS-SD printer discovery (STR #3065) - The web interface and scheduler did not support URIs up to 1024 bytes in length (STR #3072) - Fixed pdftops issues with page sizes (STR #3063) - Fixed pdftops issues with Ghostscript (STR #3062) - The scheduler incorrectly registered default profiles for PostScript printers with no specified colorspace. - The scheduler incorrectly created an empty org.cups.printers.plist file on Mac OS X. - cupsGetPPD3() did not look for local PPDs in the right directory. - SNMP lookups via side-channel did not work for NULL-VALUE and and OCTET-STRING OIDs containing nul characters. - The libusb-based USB backend did not work. - The scheduler did not set the printer-commands attribute correctly for some PPDs. - The ppdi utility did not work. - The web interface no longer uses multi-part output with old or broken web browsers (STR #3049) - CUPS now conforms to the draft IPP/2.0 and IPP/2.1 specification. - Added a new cupsGetConflicts() API to get a list of conflicting options. - The PPD compiler didn't localize options or choices that did not have associated translation text (STR #3045) - Updated the Spanish localization (STR #3043) - Fixed build problems (STR #3040, STR #3047) - cupsResolveConflicts() did not resolve using the default option choice in some cases due to the mirror UIConstraints that are present in most PPD files. - The scheduler did not honor MIME type priorities. - The commandtops filter incorrectly used the JCLBegin code to end its jobs. - The default BrowseLocalProtocols value was not set properly. - Since the commandtops filter does not actually support ReportLevels all on its own, don't list that printer command by default for PS printers. - The scheduler did not give filters a chance to log errors or update printer attributes when a job was canceled. - The scheduler did not clear the "connecting-to-device" reason keyword when a job finished.
