- CUPS 2.0.3 - security updates
- Security: Fixed CERT VU #810572/CVE-2015-1158/CVE-2015-1159
exploiting the dynamic linker (STR #4609)

- Fixed lpadmin when both -m and -o are used (STR #4578)

- The scheduler could get caught in a busy loop (STR #4605)
- The sample Epson driver could crash (STR #4616)
- The IPP backend now correctly monitors jobs
(<rdar://problem/20495955>)
- The ppdhtml and ppdpo utilities crashed when the -D option was used
before a driver information file (STR #4627)
- ippfind incorrectly substituted "=port" for service_port.
- The IPP/1.1 test file did not handle the initial print job
completing early (STR #4576)
- Fixed a memory leak in cupsConnectDest (STR #4634)
- PWG Raster Format output contained invalid ImageBox values
(<rdar://problem/21144309>)
- Added Russian translation (STR #4577)
- Added German translation (STR #4635)
- CUPS Filters v1.0.69 release - near future (Till)
- cups-browsed: When generating a PPD for an auto-discovered IPP
network printer, create a "ColorModel" option only if valid
choices are reported for it by the IPP printer.
- cups-browsed: Updated PPD file generator for auto-generated queues
for IPP network printers from the CUPS 2.1.x upstream code, so that
floating-point numbers are written in a locale-neutral way
(CUPS STR #4579).
- cups-browsed: When checking whether a queue name already exists
as a locally defined queue, do case-insensitive comparing as for
CUPS printer names are case-insensitive. This assures that
already existing queues do never get overwritten.
- cups-browsed: Added "IPPPrinterQueueType Auto/PPD/NoPPD" directive
to cups-browsed.conf to allow controlling how cups-browsed
creates queues fr native IPP network printers: with PPD, with
System V interface script, or selecting automatically.
- pdftopdf: Center Landscape-oriented jobs correctly on the page
if the "fitplot" or "number-up" options are used (Bug #1284).
- pstopdf: Removed "-dUseCIEColor" from the Ghostscript command line.
In modern Ghostscript versions (9.11 and newer) it is recommended to
not use it with the pdfwrite and ps2write output devices any more.
- imagetopdf: Corrections in PDF output: Let evince display the PDF
with the correct size including margins and let ghostscript not
complain about an invalid xref entry.
- cups-browsed: Do not add options to the System V interface script
which calls sys5ippprinter but set the options as defaults for the
CUPS queue in printers.conf.
- cups-browsed: When auto-generating a PPD-less print queue for an
IPP network printer, determine default page size, unprintable
margins, and color space from the printer via an IPP request.
- imagetopdf: Debug logging should be only controlled by the LogLevel
of CUPS, not by an awkward build time switch.
- cups-browsed: Determine from the TXT records of the Bonjour
broadcast of an IPP network printer whether it has color and duplex
capabilities and if yes, let auto-generated PPD-less print queues
use appropriate command line options to make use of these
capabilities.
- imagetopdf: Make this filter also work with auto-generated PPD-less
print queues for IPP network printers.
- sys5ippprinter: Renamed pdftoippprinter to reflect that it is
once a System 5 interface script and second does not accept only
PDF as input.
- pdftoippprinter: Support also PWG Raster and JPEG as input formats
so that an auto-generated, PPD-less queue for an IPP printer
emulates an IPP Everywhere printer.
- CUPS Filters v1.0.68 release on 13 April 2015 (Till)
- cups-browsed: Numeric IDs for GSources of the glib event
loop must be positive integers greater than zero according
to the documentation of the g_source_get_id() function.
Taken care of this at all places.
- cups-browsed: Added conditionals so that it also builds with
CUPS 1.5.x (but then withou support for automatically creating
queues for IPP network printers). Thanks to Johannes Meixner
from SUSE for the patch (Bug #1268).
- Ricoh-PDF_Printer-PDF.ppd: Added PPD file for Ricoh's PDF
printers (experimental). Thanks to Ulrich Wehner from Ricoh
for the file.
