I disagree with this change, from July:
https://gerrit.wikimedia.org/r/#/c/13558/
The message 'version-poweredby-others', which shows up when you add '...' to a list of authors in $wgExtensionCredits, was changed from just reading "others" (in English), to being a link to the MediaWiki CREDITS file. This makes sense for core MediaWiki, of course, but it doesn't make any sense for extensions - and many extensions use that '...' notation. I believe the change should be reverted, and the linking should instead be done in whatever code specifically handles the display of core MediaWiki credits in Special:Version.
Version: 1.20.x
Severity: trivial
