   | 9281    | Bug #155993 - Update environment.bz2 after postinst in case  |
   | zmedico | installation phases need to pass some variables to           |
   |         | uninstallation phases.                                       |

   | 9283    | Bug #209144 - For emerge --sync, don't return 0 when the     |
   | zmedico | server is out of date.                                       |

   | 9285    | Bug #208782 - Consistently use double quotes rather than     |
   | zmedico | mixining in single quotes.                                   |

   | 9287    | Bug #208743 - Clarify dosed docs to indicate that sed is     |
   | zmedico | performed in place of a file in ${D}.                        |

   | 9289    | Bug #208708 - Fix warnings for system or world packages that |
   | zmedico | are masked.                                                  |

   | 9290    | Add DISTDIR to the EbuildQuote.var_names. Thanks to          |
   | zmedico | Betelgeuse.                                                  |

   | 9292    | Don't show unmasked packages (currently installed packages)  |
   | zmedico | in the masking display.                                      |

   | 9293    | Bug #208708 - Fix masked package display some more: - Warn   |
   | zmedico | if all matching ebuilds are masked or the installed package  |
   |         | itself is masked. - Do not warn if there are simply no       |
   |         | matching ebuilds since that would be annoying in some cases. |

   | 9299    | Fix some broken variable references found by pyflakes.       |
   | zmedico |                                                              |
