   | 12174   | If pkg_nofetch needs to be spawned inside fetch() and it     |
   | zmedico | happens that PORTAGE_BUILDDIR doesn't exist, like when       |
   |         | called by digestgen(), use mkdtemp to create a private       |
   |         | temporary directory so that pkg_nofetch can be spawned       |
   |         | (directory needed to satisfy safe $PWD requirement of bug    |
   |         | #239560). This is more user friendly since before the        |
   |         | pkg_nofetch phase would simply be skipped in this case.      |
   |         | Thanks to Petteri Räty <betelgeuse@g.o> for reporting.      |

   | 12176   | Bug #249586 - Use writemsg() to send output to stderr        |
   | zmedico | instead of stdout.                                           |

   | 12179   | Bug #250212 - Add a new 'upstream.workaround' qa category,   |
   | zmedico | and use it for the EMakeParallelDisabled check. Thanks to    |
   |         | Mike Auty <ikelos@g.o> for this patch.                       |

   | 12180   | Avoid TypeError in BlockerCache.__iter__() that's triggered  |
   | zmedico | with FEATURES=python-trace. Thanks to Fabian Groffen         |
   |         | <grobian@g.o> for reporting.                                 |

   | 12181   | Fix deprecated_profile_check() to account for                |
   | zmedico | PORTAGE_CONFIGROOT. Thanks to Jeremy Olexa <darkside@g.o>    |
   |         | for the initial patch.                                       |
