   | 10126   | Buf #219294 - Fix 'date' and 'cut' arguments for BSD         |
   | zmedico | userland. Thanks to RB <aoz.syn@gmail.com> for this patch.   |

   | 10127   | Use absolute paths for files in ${DISTDIR}. Thanks to RB     |
   | zmedico | <aoz.syn@gmail.com> for this patch.                          |

   | 10130   | Similar to the circular dependency display, handle the       |
   | zmedico | unsatisfied blocker display inside _serialize_tasks() since  |
   |         | that's a convenient place to bail out.                       |

   | 10132   | * Move circular deps and blocker displays to                 |
   | zmedico | depgraph.display_problems(). * Always call                   |
   |         | display_problems() since calling it from inside display()    |
   |         | can lead to unwanted recursion.                              |

   | 10134   | Improve --resume handling of saved "favorites" argument      |
   | zmedico | atoms: * Save the favorites in oneshot mode too since        |
   |         | they're still useful for restoring state upon --resume. *    |
   |         | Add a depgraph._load_favorites() method to resume state from |
   |         | a previous select_files() call. This allows Package          |
   |         | instances to be matched with DependencyArg instances during  |
   |         | graph creation.                                              |

   | 10136   | Fix logic so display_problems() gets called every time       |
   | zmedico | display() does.                                              |

   | 10137   | Fix display_problems() logic some more.                      |
   | zmedico |                                                              |

   | 10139   | When loadResumeCommand() rejects a resume list, give a more  |
   | zmedico | informative explanation.                                     |

   | 10141   | Don't clean out old resume lists when in --ask or --pretend  |
   | zmedico | mode.                                                        |

   | 10143   | When a --resume list is rejected due to unsatisfied deps,    |
   | zmedico | display a list of missing deps and which packages they       |
   |         | belong to.                                                   |

   | 10145   | When a resume list is rejected, display the invalid resume   |
   | zmedico | list data in case the user is interested. This is enabled    |
   |         | with --verbose or --debug.                                   |

   | 10147   | Validate all the data types inside BlockerCache._load() so   |
   | zmedico | that any corruption is detected as soon as possible.         |

   | 10149   | In BlockerData._load(), salvage as much cache as possible    |
   | zmedico | when some seems to be corrupt.                               |
