Description Robin Johnson archtester Gentoo Infrastructure gentoo-dev Security 2015-11-11 20:53:53 UTC 
Please improve --update-changelog to allow parallel threads, to generate ChangeLogs per package in parallel; this is already supported for other parts of egencache.

This should be in addition to any future work for incremental processing (based on a last known commit).
