    - Fixed build errors adding a "go mod init"
    - Binaries are now compiled with PIE support
    - Also client service is symlinked so to avoid warnings
    - Use %{_udevrulesdir} instead of abusing %{_libexecdir}.
    - BuildRequire pkgconfig(systemd|udev) instead of systemd and udev:
      Allow OBS to shortcut through -mini flavors.
    - Name the rpmlintrc file according the policy: cryptctl-rpmlintrc.
    - Replace references to /var/adm/fillup-templates with new
      %_fillupdir macro (boo#1069468)
    - Add previously missing systemd service cryptctl-client.service
      into RPM content, continue with bsc#1056082.
    - Upgrade to upstream release 2.3 that brings a new feature to allow
      system administrators to issue mount/umount commands to client
      computers via key server. (bsc#1056082)
    - Upgrade to upstream release 2.2
