I'd like to remove the old versions and revisions of pecl-event (everything except 1.11.1-r1) as part of bug #512184. Is that a problem, or is the new version a drop-in replacement for the old ones?
Yes, the older versions are whether obsolete, or buggy. They can be removed.
Thanks, done! https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=d6326ac3ffd3e24bca9ce110d987bd3aedf17c49
