   | 9301      | Bug #208708 - Show informative warning messages for        |
   | zmedico   | installed packages that are masked.                        |

   | 9307      | removing obsolete cruft                                    |
   | genone    |                                                            |

   | 9308      | new script for creating release tarballs                   |
   | genone    | (Deleted in Prefix as we have a working tarball.sh)        |

   | 9309      | minor documentation updates                                |
   | genone    |                                                            |

   | 9310      | more minor doc updates regarding package sets              |
   | genone    |                                                            |

   | 9311      | add preserve-libs info to make.conf.example                |
   | genone    |                                                            |

   | 9312      | add tagging capabilities and cli options                   |
   | genone    |                                                            |

   | 9313      | Bug #208743 - Update dosed docs to indicate that           |
   | zmedico   | "s:${D}::g" is used as the default expression if none      |
   |           | other is given.                                            |

   | 9316      | fix nasty typo                                             |
   | genone    | (Prefix already had most of this fix)                      |

   | 9318      | Fix get_mask_info() to properly pass the "installed"       |
   | zmedico   | attribute into the Package constructor.                    |

   | 9320      | Fix the exitcode logic for bug #209144 so that when the    |
   | zmedico   | server is out of date it's not interpreted like an actual  |
   |           | rsync exitcode (to avoid a misleading exitcode             |
   |           | interpretation message).                                   |

   | 9321      | Bug #209144 - For emerge --sync, show an informative error |
   | zmedico   | and don't return 1 when PORTAGE_RSYNC_RETRIES is exceeded. |

   | 9324      | Fix CHOST masking logic wrt installed packages so that     |
   | zmedico   | it's consistent between visible() and                      |
   |           | get_masking_status().                                      |

   | 9326      | Fix rejects.                                               |
   | zmedico   |                                                            |

   | 9327      | Remove the killparent() function and associated SIGINT     |
   | zmedico   | trap since this should already be handled on the python    |
   |           | side and it won't work with dropped privileges anyway.     |

   | 9328      | fix more trivial issues breaking repoman                   |
   | genone    |                                                            |

   | 9330      | Bug #209538 - Disable annoying "masked by keyword"         |
   | zmedico   | warnings for installed packages. We can assume that if the |
   |           | user accepted the keywords at merge time then they never   |
   |           | want to be bothered again.                                 |

   | 9332      | Add bits about namespace pollution, add whitespacing       |
   | WarnerBro | comments after looking at some new code I wrote and        |
   |           | realizing I was not following the current style. Fix typos |

   | 9333      | Bug #209768 - Fix --search "Size of files:" handling so    |
   | zmedico   | that it properly shows the "Unknown (missing digest)"      |
   |           | message instead of a traceback.                            |
