   | 7647      | Fix ACCEPT_KEYWORDS validation so that ** is valid.        |
   | zmedico   |                                                            |

   | 7651      | Just use os.listdir() since portage.listdir() is           |
   | zmedico   | unnecessary.                                               |

   | 7652      | Try harder to figure out what OS we are running            |
   | WarnerBro |                                                            |

   | 7653      | Bug #189743 - Add .jpeg to the list of extensions          |
   | zmedico   | supported by dohtml.                                       |

   | 7655      | Show cache miss/hit counts all on one line, using \r to    |
   | zmedico   | return to the beginning of he line and rewrite it each     |
   |           | time that a counter is updated. Thanks to Mike "Fuzzy"     |
   |           | Partin <fuzzy@smoke.dope.org> for this patch (submitted on |
   |           | the gentoo-portage-dev mailing list).                      |

   | 7656      | Send cache hit/miss status updates to stdout instead of    |
   | zmedico   | stderr and add some more flush() calls.                    |

   | 7659      | Make --info detect more /etc/*-release files as suggested  |
   | zmedico   | by grobian.                                                |

   | 7661      | Bug #188703 - Don't adjust permissions in ${T} unless      |
   | zmedico   | userpriv is enabled.                                       |

   | 7663      | Pass complete package metadata from depgraph.select_dep()  |
   | zmedico   | into create() in order to minimize aux_get calls.          |

   | 7664      | Make best() return early when it's only given one          |
   | zmedico   | packages.                                                  |

   | 7665      | Fix update_dbentry() to process version components         |
   | zmedico   | properly before passing them into ververify().             |

   | 7666      | Make depgraph.select_dep() reuse cached metadata from      |
   | zmedico   | nodes that have already been added to the graph.           |

   | 7671      | Skip --newuse checks for nodes that have already been      |
   | zmedico   | added to the graph as "merge" nodes.                       |

   | 7672      | Prevent output from being flushed to the console too       |
   | zmedico   | frequently in dir_get_metadata().                          |

   | 7674      | Use INFORM to colorize the package name.                   |
   | zmedico   |                                                            |

   | 7676      | Fix a typo from r7663.                                     |
   | zmedico   |                                                            |

   | 7678      | Bug #189791 - Send errors to /dev/null when debug-print()  |
   | zmedico   | fails to write to ${T}/eclass-debug.log.                   |

   | 7680      | Make depgraph.create() avoid metadata lookups for binary   |
   | zmedico   | packages and ebuilds in cases where an installed package   |
   |           | has already been added to the graph. This greatly improves |
   |           | performance when the graph contains a large number of      |
   |           | installed packages.                                        |

   | 7682      | In config.regenerate(), skip loading /etc/profile.env if   |
   | zmedico   | it's mtime hasn't changed.                                 |

   | 7684      | Bug #189791 - Define EBUILD_PHASE=unpack during the        |
   | zmedico   | nofetch phase since otherwise we get EBUILD_PHASE=merge    |
   |           | which isn't in our list of valid EBUILD_PHASES recognized  |
   |           | by elog.                                                   |

   | 7686      | Make depgraph.select_dep() node reuse work when in         |
   | zmedico   | --usepkgonly mode.                                         |

   | 7688      | Add * and ~* to the list of valid values for               |
   | zmedico   | ACCEPT_KEYWORDS.                                           |

   | 7690      | Fix a typo.                                                |
   | zmedico   |                                                            |

   | 7691      | Fix another typo.                                          |
   | zmedico   |                                                            |

   | 7692      | Use a config.reload() method to explicitly reload          |
   | zmedico   | /etc/profile.env when setting up the ebuild environment.   |

   | 7693      | Call config.regenerate() after config.reload() so that the |
   | zmedico   | incrementals are restacked.                                |

   | 7694      | Don't cache results from match_from_list() since           |
   | zmedico   | *dbapi.match() caches do the job.                          |

   | 7695      | Remove pointless information from --info output            |
   | genone    |                                                            |
