commit fb7179696c51228c24eca280364405065f4cff48 Author: Pacho Ramos <pacho@gentoo.org> AuthorDate: Sat Jul 2 12:19:34 2016 Commit: Pacho Ramos <pacho@gentoo.org> CommitDate: Sat Jul 2 12:43:10 2016 dev-libs/appstream-glib: Drop old Package-Manager: portage-2.3.0_rc1 dev-libs/appstream-glib/Manifest | 1 - dev-libs/appstream-glib/appstream-glib-0.5.0.ebuild | 61 -------------------------------------- 2 files changed, 62 deletions(-) This commit removed last stable ppc & sparc versions, therefore breaking dependencies of dev-util/appdata-tools and games-puzzle/atomix. I've reverted it to restore depgraph consistency. If you'd like to drop the package from stable ppc & sparc, please remove the stable keywords (or appropriately versions) from listed revdeps first. Otherwise, I suggest you stabilize the newer version on ppc & sparc.
Ok, found the stablereq.
