please add =media-libs/libpng-1.2.50 (amd64 and x86 only!) =media-libs/libpng-1.5.13 (everyone) to package.keywords and start testing them now and mark them stable in a week if no problems arise
Changed to libpng-1.5.13-r1 because of bug 436996
tested =libpng-1.5.13-r1 amd64: all fine here
05 Oct 2012; Brent Baude <ranger@gentoo.org> libpng-1.2.50.ebuild, libpng-1.5.13-r1.ebuild: Marking libpng-1.2.50 and libpng-1.5.13-r1 for bug 436592 You only required libpng-1.5.13-r1.
x86 ok (repoman ok, compiles ok)
this is good to go, please mark stable, and as Jer pointed out, only stabilize what you need... It's pointless to file stablereqs for arch's that never need it... wastes everyones time. And sorry, but I'd like to point out certain ppc* developers for reading only $summaries of stablereq bugs and going with that with some semi-poorly automagic script I mean, I've picked up those pieces so much it's just tiresome, no offense ;)
Stable for HPPA.
