+ behaviour is only applied to wikitable-start {|, but the first line of a wikitable
+ cell is now treated as a linestart.
+* Custom editintro's using the editintro url parameter will no longer show <noinclude>
+ sections on pages they are included on.

+ adding overflow:hidden to h1,h2,h3,h4,h5,h6 (also fixes editsection bunching).

+ and add a comment to the ini control file explaining what is going on.
+* Trying to upload a file with no extension or with a disallowed MIME type now gives
