Branch: MAIN
Changes since 1.126: +18 -15 lines
Go back to use a variable rather than an array for _LATEST_AUTOMAKE, use versionator eclass to go back to the full version instead, so that it's clear what's going on and other developers don't misread the code. It's only perfect for EAPI >= 0 but it's not broken on EAPI=0 anyway.
