* 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
* Mark private methods private using a keyword.
* Reject arrays with count == 2: these will fail when you do array_slice( ... , 1 ).
* Treat xor consistent with the other operations: if there's only one parameter the result should just evaluate that, not always return false; and any number of parameters should be allowed.
* Fail fast on bad input: throw an exception if Autopromote encounters a condition it can't understand (after asking extensions).
* Code documentation! There were five lines of comments in the original commit.
* APCONDS_INGROUPS is not used, or for that matter defined.
* Editcount should use >=, not >, for consistency with past behavior and intuitiveness.
* "autopromoteUser" sounds like it's actually promoting the user somehow. Renamed the function to getAutopromoteGroups.
* Make sure we don't return the same group more than once, when we're returning a group. Probably not going to hurt, but may as well be clean.
* Made it possible to configure the parser class being used, via $wgParserConf.
* Moved defines from the top of Parser.php to either class constants or Defines.php
* Added Parser_DiffTest, a differential parser class for regression testing
* Added Parser_OldPP, a parser class which operates like the parser before this commit. I made one breaking change: a bugfix to avoid losing whitespace when adding MWTEMPLATESECTION markers.
* Made internal tidy work with PHP 5
* Added the ability to supply a hook for template fetching via ParserOptions. This is handy for testing.
* Updated parserTests.txt to account for the various breaking changes I made. Removed a few parser tests that no longer test for anything useful.
* Added support for configuration of an arbitrary number of commons-style file repositories.
* Split Image.php into filerepo/File.php and filerepo/LocalFile.php
* Renamed Image::getImagePath() to File::getPath()
* Added initial support for timestamp-based file fetching (OldLocalFile), to be expanded upon by aaron.
* Changed the interface for Image/File object creation: use wfFindFile() or wfLocalFile() depending on semantics
* ImageGallery::add() now accepts a title object as the first parameter
* Moved file handling operations on upload from SpecialUpload to File
* Removed path-related functions from ImageFunctions.php. Removed static path accessors from File.
* Added a Content-Disposition header to thumb.php output
* Improved thumb.php error handling
* Updated the unit test suite to kind of partially work with modern computers. RunTests.php doesn't work just yet. Fixed an actual regression that the test suite detected -- moved some defines to Defines.php where they will be loaded consistently.
* Deleted DatabaseMysql.php, no longer necessary, database classes are autoloaded.
* Moved wfGetMimeMagic() to MimeMagic::singleton()
* Fixed a couple of __CLASS__.'::'.__FUNCTION__ things.
* Made lines from initialiseMessages() appear as list items during installation
* Moved the bulk of the localisation data from the Language*.php files to the Messages*.php files. Deleted most of the Languages*.php files.
* Introduced "stub global" framework to provide deferred initialisation of core modules.
* Removed placeholder values for $wgTitle and $wgArticle, these variables will now be null during the initialisation process, until they are set by index.php or another entry point.
* Added DBA cache type, for BDB-style caches.
* Removed custom date format functions, replacing them with a format string in the style of PHP's date(). Used string identifiers instead of integer identifiers, in both the language files and user preferences. Migration should be transparent in most cases.
* Simplified the initialisation API for LoadBalancer objects.
* Removed the broken altencoding feature.
* Moved default user options and toggles from Language to User. Language objects are still able to define default preference overrides and extra user toggles, via a slightly different interface.
* Don't include the date option in the parser cache rendering hash unless $wgUseDynamicDates is enabled.
* Merged LanguageUtf8 with Language. Removed LanguageUtf8.php.
* Removed inclusion of language files from the bottom of Language.php. This is now consistently done from Language::factory().
* Add the name of the executing maintenance script to the debug log. Start the profiler during maintenance scripts.
* Added "serialized" directory, for storing precompiled data in serialized form.
* Introduced doEdit(), a simplified editing API. Rewrote updateArticle() and insertNewArticle() to call doEdit() and marked them deprecated. Callers should be updated to use doEdit() at a later date.
* Replaced $fname with __METHOD__
* Removed some unused member variables
* Fixed cache purging on null edit, hopefully it should work the same as action=purge now.
* Fixed doRedirect() callers, minor bug introduced with HTMLCacheUpdate.
