Hello everyone,
The prior maintenance release announcement email titled
MediaWiki Security and Maintenance Releases: 1.23.6, 1.22.13 and 1.19.21
included the word "Security" in the subject. This inclusion was a mistake. There are no security fixes included in these releases.
Best, Mark A. Hershberger (Wiki Release Team)
