- CUPS Filters v2.1.1 release on 18 February 2025
- Bug fix release
- Correct adding blank page when printing even/odd pages for manual duplex
- The page-set option with choices even and odd is designed for doing manual duplex, by
printing the odd pages first, turning the printed pages over and put them back into the
input tray and then print the even pages. If the total number of pages is odd, a blank
page needs to get added. This change does corrections to make this work correctly
(cups-filters issue #541).
- Do not default to input page size Letter when job format defines page sizes
- For input formats which define the absolute size dimensions for each page (PostScript,
PDF, CUPS/PWG/Apple Raster) we do not default to US Letter if no input page size is
given (Issue #68, pull request #69).
- Fix transferring error exit status from children in filter functions
- The Ghostcript and MuPDF filter functions did not transfer error exit codes from the
called command line utilities and returned the successful exit code from another called
utility instead (Issue #76, pull request #77).
- bannertopdf.c: Fix segfault when printing banners/test page (Pull request #80)
- Fix issues reported by OpenScanHub
- Open source static analyzer OpenScanHub found several issues regarding resource leaks,
security, buffer overflows etc. which are fixed now. libcupsfilters passes sanity testing
with the changes (Pull request #79).
- Update testfilters.c to resolve issues with different build directories (Issue #66, pull
request #74)
