   | 12494   | Simplify depgraph._select_pkg_from_graph() by using          |
   | zmedico | match_pkgs().                                                |

   | 12495   | Bug #254860 - Inside _expand_new_virtuals(), generate        |
   | zmedico | instances of Atom instead of plain strings, so calling code  |
   |         | can assume that only Atom instances will be returned when    |
   |         | strict mode is enabled.                                      |

   | 12496   | Use a new 'usersync' feature to control dropping of          |
   | zmedico | privileges for --sync, since it's fairly common for people   |
   |         | to have inconsistent permissions between $PORTDIR and        |
   |         | contained files/directories.                                 |

   | 12497   | Bug #254860 - Add another missing str -> atom conversion     |
   | zmedico | inside _expand_new_virtuals().                               |

   | 12498   | Bug #254825 - Improve messages that are displayed when       |
   | zmedico | manifest generation bails out due to a changed distfile      |
   |         | digest.                                                      |

   | 12499   | Inside digestgen(), don't unnecessarily call fetch() in      |
   | zmedico | cases when the there are no hashes for comparison and the    |
   |         | file already exists in $DISTDIR.                             |

   | 12500   | Bug #254825 - Add a note about the need to use `ebuild       |
   | zmedico | --force manifest` to update distfiles digests.               |

   | 12501   | In spawn(), put the full cpv in opt_name, instead of just    |
   | zmedico | $PF. Thanks to Diego Pettenò <flameeyes@g.o> for the        |
   |         | suggestion.                                                  |

   | 12502   | Make sure spawn() always initializes opt_name because later  |
   | zmedico | code assumes that it is.                                     |

   | 12503   | Add some more variables to config._env_blacklist to ensure   |
   | zmedico | that they never leak in from the calling environment.        |

   | 12514   | Fix repoman conditionals inside _expand_new_virtuals() to    |
   | zmedico | use config.local_config instead of checking for portdbapi    |
   |         | type.                                                        |

   | 12518   | Don't show the running Linux kernel version in the commit    |
   | zmedico | message, since it might leak information that would be       |
   |         | useful to attackers. Thanks to Ned Ludd <solar@g.o> for the  |
   |         | suggestion.                                                  |

   | 12519   | Drop the kernel version from the commit message for all      |
   | zmedico | platforms. Thanks to Fabian Groffen <grobian@g.o> for the    |
   |         | suggestion.                                                  |

   | 12520   | Call depgraph._set_args() inside _load_favorites(), to       |
   | zmedico | eliminate duplicate code.                                    |
