   | 10586    | Add vardbapi.aux_get() support for an "_mtime_" value which |
   | zmedico  | corresponds to the installed package directory's mtime      |
   |          | (numeric value from stat result). This value can be used to |
   |          | validate indexes or caches used in the optimization of vdb  |
   |          | query operations for various types of package metadata such |
   |          | as dependencies and file contents.                          |

   | 10587    | Add Package.counter and mtime attributes.                   |
   | zmedico  |                                                             |

   | 10588    | Add a PackageVirtualDbapi.__getitem__() method.             |
   | zmedico  |                                                             |

   | 10589    | Bug #224271 - Add a 'IUSE is not defined' ebuild.minorsyn   |
   | zmedico  | warning.                                                    |

   | 10591    | remove old/unused gen_wrapper function                      |
   | SpankMan |                                                             |

   | 10592    | As suggested by Flameeyes, add a new 'inherit.autotools'    |
   | zmedico  | check which warns when autotools has been inherited but     |
   |          | none of the eautomake, eautoconf or eautoreconf functions   |
   |          | are called like they are supposed to be.                    |

   | 10593    | Bug #224271 - New check 'IUSE.undefined', renamed from      |
   | zmedico  | generic 'ebuild.minorsyn'.                                  |

   | 10594    | Make load_emerge_config() filter out empty                  |
   | zmedico  | PORTAGE_CONFIGROOT and ROOT values, and those containing    |
   |          | only whitespace.                                            |

   | 10596    | Validate ROOT from make.conf.                               |
   | zmedico  |                                                             |

   | 10598    | Inside, create_trees(), pass target_root="/" into the       |
   | zmedico  | config constructor when necessary to override the setting   |
   |          | in make.conf.                                               |

   | 10600    | Make repoman pass Package instances into run_checks(), so   |
   | zmedico  | that the checks can use the Package.mtime and inherited     |
   |          | attributes.                                                 |

   | 10601    | Fix typo.                                                   |
   | zmedico  |                                                             |

   | 10602    | Add additional functions such as eaclocal and eautoheader   |
   | zmedico  | to the inherit.autotools regex. Thanks to Arfrever.         |

   | 10603    | Make portdbapi.aux_get() return float type for _mtime_.     |
   | zmedico  |                                                             |

   | 10604    | Bug #225285 - Allow digestcheck() to succeed when the       |
   | zmedico  | Manifest is missing and strict mode is disabled.            |
