-=== Security changes ===
-* (bug 32276) Skins were generating output using the internal page title which
- would allow anonymous users to determine wheter a page exists, potentially
- leaking private data. In fact, the curid and oldid request parameters would
- allow page titles to be enumerated even when they are not guessable.
-* (bug 32616) action=ajax requests were dispatched to the relevant internal
- functions without any read permission checks being done. This could lead to
- data leakage on private wikis.
