* 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.
* Allow or disallow account creation from blocked IP addressess on a per-block basis.
* Prevent duplicate blocks.
* Fixed the problem of expiry and unblocking erroneously affecting multiple blocks.
* Fixed confusing lack of error message when a blocked user attempts to create an account.
* Fixed inefficiency of Special:Ipblocklist in the presence of large numbers of blocks; added indexes and implemented an indexed pager.
* remove require_once() throughout whole code, yet left in few places
* move global functions in HttpUtils, ProxyTools, Credits to class methods
* php5 only: __autoload() now used, combined with class->file map and require()
* move initialization of $wgValidSkinNames to Skin::getSkinNames()
* few more changes that will surely break stuff.
Inserting a newline into some improperly filtered option strings could be used to overwrite other pref values, bypassing their input validation. Any newlines now get filtered out at User::setOption as a final line of defence.
There were a few HTML injection bugs, but none appear to be exploitable, as prefs can only be set if you already control the account.
Bug found by gmaxwell.
* (bug 675) Add page protection level for unregistered/new accounts
* User::isNewbie now uses the registration date and $wgAutoconfirmAge
* Log views show message when no matches
(used to spontaneously switch to Classic skin for old numeric pref records)
This one keeps biting me when I log in on wikis I haven't been to in a year
or two, then change prefs.
