   [ Mihai Moldovan ]
   * New upstream version (0.6.1.3):
     - misc: pre-release copyright update.
     - man/man1/pyhoca-cli.1: pre-release date update.
     - misc: change http:// to https:// links where appropriate.
   * debian/control:
     + Change http:// to https:// links where appropriate.
   * debian/copyright:
     + Change http:// to https:// links where appropriate.
   * debian/watch:
     + Change http:// to https:// links where appropriate.
   * pyhoca-cli.spec:
     + Change http:// to https:// links where appropriate.
     + Drop Python 2 support for OpenSuSE Leap 15.4+ and Tumbleweed (and ALP).
     + Remove pycache handling from the files list. Python-2-variants don't
       have the concept of __pycache__ directories at all, so using
       %pycache_only there is redundant. Python-3-variants sprinkle __pycache__
       directories wherever there are .py files, which means that they are
       conveniently contained in the "pyhoca" subdirectory of sitelib. Older
       *SuSE versions, including Leap, just ignored files or directories in the
       %files list that do not exist, but Tumbleweed is throwing an error if
       you try to include a file or directory that does not exist. The fix is
       easy: don't try to include the non-existent __pycache__ top-level
       directory.
