I consider it likely that 2.14.2 contains more known regressions against 2.12.3 or later than 2.15.41 does. If a "regression" is not important enough to make a backport to the _current_ _stable_ _release_, why is it important enough to completely kill the next stable release? > After all, that is the point of making release condidates, isn't it - > to identify new bugs so they can be fixed before the stable is > released? No. The point of making release candidates is to identify bugs of a severity that precludes making a stable release. Not just any old bug. >> But that nicety pales against the garishness of not giving the users >> anything ever. > > I agree with your general sentiment - we need to find a way of > controlling the introduction of new bugs as a new stable become due. A new stable is always due, and new bugs are introduced always. We need to adequately deal with the consequences. > We have the technology to identify the commits that introduce bugs > fairly easily.

After the stable release is before the stable release. We can't freeze development while we are unable to get a sane release process going. That would be, like, permanent. One could try such a revert strategy on a stable release _branch_, but it is not unlikely to lead to cascades of reverts, since quite a few fixes are also intended to cure regressions by themselves. And reverts of increasingly older commits have increasingly stranger interactions with developments that happened in between (and that does not just mean merge conflicts). -- David Kastrup _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-devel
