* Add a cache so that calling getcategorycount for the same category many times won't stupidly repeat the same query over and over. Currently an early return avoids incrementing the expensive function count in this case, so technically this makes things *slower*, not faster, but that can be tweaked if anyone cares.
* PHP 5.3 compatibility fix for wfRunHooks() called with no parameters
An autoloaded 'Namespace' class alias is retained for compatibility with
extensions which haven't updated to the new class name... however they too
will break on PHP 5.3. Yay!
* Added page_props backend, generic parser-driven page properties which, when changed, invalidate the cache of backlinked pages on any links table. Could be used to add overlays to images depending on their deletion status, or to add icons to articles based on category membership.
* Refactored double-underscore handling in the parser.
* Moved CoreParserFunctions registration to CoreParserFunctions.
* Made ==foo==<!----> create a valid section edit link
* Changed header processing heuristics -- now double-equals signs are generally respected as header starts, and will break template invocations, and single equals signs are respected as header syntax but might not generate a section edit link.
* Fixed #tag behaviour in preprocess()
* Fixed #tag quote stripping regex
* Made MessageCache::getMessage() never transform its result, that is now left up to the caller.
* A few other minor changes
Giving this a |nowiki option to wrap the returned path in <nowiki>s for non-linked standalone use.
Added File::getFullURL() function for cleaner calls; using full path to ensure consistency here.
* Clean up the mess in ParserOutput
* Reject (ignore) custom titles which don't normalise to the same as the current page -- THIS IS IMPORTANT OTHERWISE LINKING GOES TO POT (and not the good kind of pot)
[WARNING: Touches parser version. Old caches will be expired. You might wish to undo this and add some temporarily backwards-compatibility for a few days.]
* Add @addtogroup tags to various classes, to try and group conceptually-related classes together.
* Add brief descriptions to various Special pages, thanks to Phil Boswell.
* Moving some docs to be right above the classes they represent, so that they are picked up.

... There are certain to be other things too, so this is not intended to be comprehensive, rather the above just stops most of the notifications I observed.
* Removed some backtracking regexes with an O(N^2) worst case, replaced with StringUtils::delimiterReplace(). There is a beneficial functional difference: /*/ is no longer considered to be a complete CSS comment.
* Changed the parser strip state from an array to an object. This should hopefully avoid the PHP bugs with array references. StripState uses the new ReplacementArray to do the replacements, thereby supporting FSS.
* Removed DatabaseFunctions.php from the default startup sequence. Moved wfGetDB() to GlobalFunctions.php.
* Introduced the SiteStats class, with a collection of cached site stats accessor functions.
* Removed all global functions from Parser.php, they don't belong there.
* Made LanguageConverter use the new ReplacementArray class instead of managing its own FSS objects.
* Enforce a reasonable maximum length to cover most uses while preventing some dickhead from doing a 500 thousand character expansion
* Use the first padding character only for similar reasons
* (bug 7081) More input validation and checking
