Hello!

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.

This release also serves as a maintenance release for these branches.
