Thread:Project:Support desk/Compatibility of MW 1.16.5 with mySQL 5.5.x/reply

Hi!

These versions should - at least mostly - be compatible. MediaWiki 1.16 is from July 2010, MySQL 5.5 from end 2010 - that should work.

However, MediaWiki 1.16 is no longer supported and has known security holes. Using MediaWiki 1.16 is no longer secure. If you want to be on the safe side, you should upgrade to MediaWiki 1.21. And MediaWiki 1.21 definitely is fully compatible with MySQL 5.5. :-)
