   | 13056   | Add new xpak.5 man page by Lars Hartmann chaotikaorg>.       |

   | 13059   | Bug #262012 - Only trigger the slot conflict message about   |
   | zmedico | --newuse when the installed version is the same as the new   |
   |         | one. If they are different versions then there's some other  |
   |         | problem.                                                     |

   | 13060   | Bug #262211 - Make vardbapi.aux_get() translate empty SLOT   |
   | zmedico | to 0 since other code expects non-empty SLOT (for generation |
   |         | package slot atoms).                                         |

   | 13061   | Bug #262211 - Avoid triggering an InvalidAtom exception      |
   | zmedico | inside the Package constructor when SLOT is empty.           |

   | 13062   | Use absolute imports instead of relative.                    |
