CUPS 2.3rc1 is now available for download. This is the first release candidate for CUPS 2.3.0 which adopts the new CUPS license, adds support for IPP presets and finishing templates, and fixes a number of bugs and "polish" issues. This beta also includes the new ippeveprinter utility. Changes include:

• The cups-config script no longer adds extra libraries when linking against
  shared libraries (Issue #5261)
• The supplied example print documents have been optimized for size
  (Issue #5529)
• The cupsctl command now prevents setting "cups-files.conf" directives
  (Issue #5530)
• The "forbidden" message in the web interface is now explained (Issue #5547)
• The footer in the web interface covered some content on small displays
  (Issue #5574)
• The libusb-based USB backend now enforces read limits, improving print speed
  in many cases (Issue #5583)
• The ippeveprinter command now looks for print commands in the "command"
  subdirectory.
• The ipptool command now supports $date-current and $date-start variables
  to insert the current and starting date and time values, as well as ISO-8601
  relative time values such as "PT30S" for 30 seconds in the future.

Enjoy!
