   | 13969   | Tweak $ROOT handling inside depgraph._add_pkg_deps() for     |
   | zmedico | removal actions, so --with-bdeps works correctly with        |
   |         | --depclean and --prune.                                      |

   | 13970   | In calc_depclean(), sort packages that are displayed due to  |
   | zmedico | being pulled in by link level dependencies.                  |

   | 13971   | Don't trigger the --root-deps code for removal actions such  |
   | zmedico | as --prune and --depclean.                                   |

   | 13972   | Fix PreservedLibsRegistry.pruneNonExisting() to work with    |
   | zmedico | $ROOT.                                                       |

   | 13973   | Use writemsg_stdout() for safe unicode output of             |
   | zmedico | --list-sets.                                                 |

   | 13974   | Bug #280962 - Fix broken path normalization inside           |
   | zmedico | StaticFileSet.multiBuilder().                                |

   | 13975   | Open new items in text mode (unicode), and safely handle     |
   | zmedico | unicode in news item names.                                  |

   | 13977   | Bug #280998 - Misc selinux fixes. Thanks to Chris PeBenito   |
   | zmedico | <pebenito@gentoo.org> for this patch.                        |

   | 13978   | Bug #280460 - Wrap os and os.path modules with unicode       |
   | zmedico | encode/decode wrappers for python-2.x.                       |
