  - Impact on distribution-independent drivers from Open Printing
    - topic for PWG/OP Summit discussion
  
  - Till is looking into keeping up the LSB at least for Ubuntu 16.04 LTS
    - but after that new ways of distribution-indpendent printer driver 
      packages must be found
  
  - Approaches?
    - partially static linking, not completely statically linking
    - completely static linking with a replacement for libc

• (2) Status of CUPS and CUPS Filters (Till)

  - CUPS CUPS source code and bug reports are handled on GitHub now
    - https://github.com/apple/cups/
  
  - CUPS release v2.1.3 on 5 February 2016 (Mike)
    - The default password function did not work on some platforms
      (STR #4750)
    - The scheduler should not exit under memory pressure
      (<rdar://problem/23255001>)
    - The EPL2 and ZPL sample drivers did not properly support the
      CutMedia option.
    - Pending subscriptions would prevent the scheduler from idle exiting
      (STR #4754)
    - Fixed some issues in ipptool for skipped tests
      (<rdar://problem/24137160>)
    - The "lp -H resume" command did not reset the "job-state-reasons"
      attribute value (STR #4752)
    - The scheduler did not allow access to resource files (icons, etc.)
      when the web interface was disabled (STR #4755)
    - Localization fix (STR #4756)
  
  
  - CUPS Filters principal changes (Till)
    - Lots of bug fixes to prepare for Ubuntu 16.04 LTS, especially a 
      problem when joining remote queues to one local queue for load 
      balancing
  
  - CUPS Filters 1.8.4 release plans (Till)
    - cups-browsed/sys5ippprinter: Fixed documentation about the
      allowed input formats for auto-created network printer queues
      using sys5ippprinter 
    - Also improved NEWS entry about renaming of sys5ippprinter 
      (Debian bug #819665)
  
  - CUPS Filters v1.8.3 release on 23 March 2016 (Till)
    - cups-browsed: When creating or modifying a local print queue
      set the printer-is-shared bit to false in a separate IPP
      request as this operation errors on queues directly pointing
      to remote CUPS queues with the IPP backend.  This way we can
      ignore the error and assure that all other settings are
      applied (Ubuntu bug #1560099).
   - Fixed pkg-config support so that $PKG_CONFIG gets used and
     cross compilation works (Bug #1347).
   - gstoraster: Put conversion rules for this filter into a
     separate file, so that they do not get installed when we
     build without Ghostscript support (Bug #1346).
   - Allow disabling dependencies on IJS (Bug #1345).
   - pdftops: Switch to Poppler as PDF renderer also for the
     Apple LaserWriter 12/640, to work around a bug in the
     printer's PostScript interpreter (Bug #1344).
