Version 3.4.1 fixes some annoying regressions in 3.4.0 (including false positives). Lets mark it stable.
+ 21 Jul 2009; <chainsaw@gentoo.org> valgrind-3.4.1.ebuild: + Marked stable on AMD64 as requested by Olivier Crete <tester@gentoo.org> + in bug #278534.
x86 stable
Marked ppc stable. PPC64 has a bug which prevents it from running on any meaningful program: https://bugs.kde.org/show_bug.cgi?id=201152 and shouldn't be keyworded until this is fixed.
ppc64 done
Stabilization of ppc64 undone after checking with Joe (see comment #3). I'm closing this one. Who knows how long until ppc64 issues are fixed.
