   | 15304   | Bug #302937 - Handle declare -r without assignment.          |
   | zmedico |                                                              |

   | 15305   | Validate categories.                                         |
   | zmedico |                                                              |

   | 15306   | Deprecate pordbapi.mysettings since the portdbapi.settings   |
   | zmedico | alias is now supported by stable portage.                    |

   | 15307   | Bug #298141 - Make /etc/portage/sets relative to             |
   | zmedico | PORTAGE_CONFIGROOT. Thanks to Martin Gysel (bearsh)          |
   |         | <m.gysel@gmx.ch> for this patch.                             |

   | 15308   | Fix @module-rebuild to support $ROOT.                        |
   | zmedico |                                                              |

   | 15309   | Clean up config incrementals handling.                       |
   | zmedico |                                                              |

   | 15310   | Simplify the conditional that triggers calculation of A and  |
   | zmedico | AA variables.                                                |

   | 15311   | Deallocate config instance when necessary, to avoid memory   |
   | zmedico | leak when in prefetch mode.                                  |

   | 15312   | Optimize parallel-fetch for the case where all files are     |
   | zmedico | already fetched and have the correct size. In this case we   |
   |         | can avoid the expense of spawning ebuild(1).                 |

   | 15313   | Make sure the fetcher process correctly inherits             |
   | zmedico | PORTAGE_CONFIGROOT.                                          |

   | 15314   | Fix deprecated portdbapi.mysettings reference.               |
   | zmedico |                                                              |

   | 15315   | Use stat rather than lstat since portage.fetch() creates     |
   | zmedico | symlinks when PORTAGE_RO_DISTDIRS is used.                   |

   | 15316   | Use Package.use.enabled where appropriate.                   |
   | zmedico |                                                              |

   | 15317   | Bug #295197 - Output a newline after valid user input is     |
   | zmedico | received.                                                    |

   | 15318   | Make verify_all() do checksums in sorted order by hash name. |
   | zmedico |                                                              |
