We will go with the new LTS branch of MediaWiki for Mageia 6. It should be released May 30/31, according to upstream: https://www.mediawiki.org/wiki/MediaWiki_1.27
Blocks: (none) => 15527
Should version 1.26 be packaged in the meantime to prepare for the upgrade (in case there are relevant packaging changes to make), or would the version bump from 1.23 to 1.27 be painless (based on previous experience)?
No, it would be better to bump it once and it should be a painless upgrade.
MediaWiki 1.27 has finally been released on June 28: https://lists.wikimedia.org/pipermail/mediawiki-announce/2016-June/000191.html
