I would like to announce the release of MediaWiki 1.28.1, 1.27.2 and 1.23.16!
These releases fix five security issues in core and one for the extension
SyntaxHighlight_GeSHi. Download links are given at the end of this email.
Please note that next month is the End-Of-Life date for MediaWiki 1.23. This
means that MediaWiki 1.23.16 will be the last security release for that
version, barring any unforeseen issues. We would strongly encourage users of
MediaWiki 1.23 to upgrade to MediaWiki 1.27, released in June 2016, or a yet
newer version as soon as possible. MediaWiki 1.27 will be supported until June
2019. See <https://www.mediawiki.org/wiki/Version_lifecycle> for more information.
