   An update that has two recommended fixes can now be
   installed.

Description:

   This update for zlib fixes the following issues:

   - Including the latest fixes from IBM (bsc#1166260) IBM Z mainframes
     starting from version z15 provide DFLTCC instruction, which implements
     deflate algorithm in hardware with estimated compression and
     decompression performance
     orders of magnitude faster than the current zlib and ratio comparable
      with that of level 1.
   - Add SUSE specific fix to solve bsc#1138793. The fix will avoid to test
     if the app was linked with exactly same version of zlib like the one
     that is present on the runtime.
