   | 14814   | Bug #292664 - Show ACCEPT_LICENSE in emerge --info.          |
   | zmedico |                                                              |

   | 14815   | Inside iter_owners, only cache a maximum of 25 dblink        |
   | zmedico | instances, in order to avoid potentially running out of      |
   |         | memory.                                                      |

   | 14816   | Add setup phases to the tail of the merge queue instead of   |
   | zmedico | the front, since otherwise when merging binary packages we   |
   |         | sometimes tend to get a large number of setup phases         |
   |         | flooding the queue and preventing queued installs from       |
   |         | running.                                                     |

   | 14817   | Implement dblink.__hash__ and __eq__, so that `portageq      |
   | zmedico | owners` correctly groups search results. Also, increase      |
   |         | iter_owners dblink cache size from 25 to 100 instances.      |

   | 14818   | Bug #292910 - Don't mix print() and writemsg_stdout(), in    |
   | zmedico | order to avoid buffering issues.                             |

   | 14819   | Bug #292820 - Make the Package constructor handle invalid    |
   | zmedico | SLOT values.                                                 |
