   | 14907   | Bug #294886 - Show some basic info at the beginning of the   |
   | zmedico | build log, including USE flags.                              |

   | 14909   | In FakeVartree.sync(), skip the aux_get wrapper when         |
   | zmedico | populating old-style virtuals, in order to avoid unwanted    |
   |         | cache generation with --nodeps (reported by Arfrever).       |

   | 14913   | Revert r14901 since it doesn't solve the problem (bug        |
   | zmedico | #294945).                                                    |

   | 14914   | Bug #294945 - Fix blocker satistfied state handling inside   |
   | zmedico | depgraph, to avoid a KeyError when displaying blockers.      |

   | 14915   | Fix deprecated usage of dep_getkey(). Thanks to Sebastian    |
   | zmedico | Mingramm (few) for reporting.                                |
