(Issue #5233)
- Fixed printing to some IPP Everywhere printers (Issue #5238)
- Fixed installation of filters (Issue #5247)
- The scheduler now supports using temporary print queues for older IPP/1.1
print queues like those shared by CUPS 1.3 and earlier (Issue #5241)
- Star Micronics printers need the "unidir" USB quirk rule (Issue #5251)
- Documentation fixes (Issue #5252)
- Fixed a compile issue when PAM is not available (Issue #5253)
- Label printers supported by the rastertolabel driver don't support SNMP, so
don't delay printing to test it (Issue #5256)
- The scheduler could crash while adding an IPP Everywhere printer (Issue #5258)
- The Lexmark Optra E310 printer needs the "no-reattach" USB quirk rule
(Issue #5259)
- Systemd did not restart cupsd when configuration changes were made that
required a restart (Issue #5263)
- The IPP Everywhere PPD generator did not include the `cupsJobPassword`
keyword, when supported (Issue #5265)
- Fixed an Avahi crash bug in the scheduler (Issue #5268)
- Raw print queues are now deprecated (Issue #5269)

correctly.
- Added public `cupsEncodeOption` API for encoding a single option as an IPP
attribute.
- Removed support for the `-D_PPD_DEPRECATED=""` developer cheat - the PPD API
should no longer be used.

accessor functions should be used instead.
