Thread:Talk:MediaWiki 1.23/Manual:Skin autodiscovery/reply (2)

Sorry, I haven't written the page yet. I'll do it this week (before the 1.23 release) and it will contain a migration guide (both for skin developers, and for site admins who just want the warnings to shut up) – it's actually rather easy to fix up, basically you need to move the MySkin.php file into the MySkin directory with skin resources (or create one if it doesn't exist), adjusts paths in it if they were relative, add the skin to $wgValidSkinNames in the Myskin.php file and add a  to your LocalSettings (similarly to how it's done for extensions).

MediaWiki 1.23 only adds the warnings – if you've acknowledged them and they bother you, then I suppose you could comment-out the line that emits them in Skin.php, in the getSkinNames method. Skins using autodiscovery will continue working like it did for years in 1.23 LTS and 1.24 (with warnings), and support will only be removed in 1.25 (and 1.27 LTS), giving you plenty of time to migrate.
