A note on upgrading

I've done the upgrade myself, and though fairly straight-forward I suggest you start fresh and move back images/*, LocalSettings.php and then re-install any plugins you want to use. Some are not compatible with the new MediaWiki version, and others will need updates to work.

Running on Apache

In order for the VisualEditor to work properly on Subpages you need to add AllowEncodedSlashes NoDecode to your vhost config.[1]
