   | 12290   | Move initial signal handlers to the launcher script.         |
   | zmedico |                                                              |

   | 12291   | Make more code conditional on POLLIN events, where           |
   | zmedico | appropriate.                                                 |

   | 12292   | Add SIGUSR1 signal handlers that call pdb.set_trace().       |
   | zmedico | Thanks to Brian Harring for the suggestion.                  |

   | 12293   | Bug #252304 - Restore the -V/--version option.               |
   | zmedico |                                                              |

   | 12294   | Fix broken PATH comparisons when eliminating duplicate       |
   | zmedico | entries inside binarytree.inject().                          |

   | 12295   | Fix PATH comparison in binarytree.inject() some more.        |
   | zmedico |                                                              |

   | 12296   | Bug #251976 - Add a QA_PRESTRIPPED variable for ebuilds to   |
   | zmedico | disable warnings about pre-stripped files.                   |

   | 12297   | Replace QA_DT_HASH with QA_PRESTRIPPED where appropriate.    |
   | zmedico | Thanks to Arfrever for reporting. Also, remove array support |
   |         | since bash arrays don't export anyway.                       |

   | 12298   | Fix typo.                                                    |
   | zmedico |                                                              |

   | 12300   | Don't use 'local' builtin outside of a function.             |
   | zmedico |                                                              |

   | 12301   | Bug #252374 - Warn if FEATURES=fakeroot is enabled, but the  |
   | zmedico | fakeroot binary is not installed.                            |

   | 12302   | Make BinpkgFetcher use longs instead of floats when          |
   | zmedico | synchronizing timestamps, since it's better not to rely on   |
   |         | float comparison here.                                       |
