* (bug 48294) API: Fix chunk upload async mode.
* (bug 46749) Broken files tracking category removed from pages if an image
with that name is uploaded.
+* (bug 14176) System messages that are empty were previously incorrectly treated
+ as non-existent, causing a fallback to the default. This stopped users from
+ overriding system messages to make them blank.
+* (bug 48319) action=parse no longer returns an error if passed none of 'oldid',
+ 'pageid', 'page', 'title', and 'text' (e.g. if only passed 'summary'). A
+ warning will instead be issued if 'title' is non-default, unless no props are
+ requested.

+ user blocks.
