In the tree for 521 days, already stable on x86, latest stable release of the project, no bugs open apart of bug #145721 (which shouldn't prevent a stabilization). Ramereth, app-backup, can we stabilize this? Also, you could remove 1.2 version, since it's unused now.
Sorry, CC'ing arches (already stable on x86 so no "pong" from maintainer is required).
sparc will stabilizie if an user requests it
Old ebuild removed and stablized the other.
