* Ended the role of $wgLinkCache in link updates. Instead, links (and related entities) are registered in the ParserOutput object during a parse. The LinksUpdate constructor now takes a ParserOutput object as a parameter. $wgLinkCache is still used, but only as a cache of article IDs.
* Because the link list is now saved and restored in the parser cache, meta tag keywords now work on parser cache hits. Some refactoring took place in this area.
* Rendering of the HTML for category links has moved from Parser to OutputPage.
* Did some general pottering around in Article.php, such as allowing an Article object to be created with a specified revision ID, thereby optionally removing the dependence on $wgRequest. Not used at the current time.
* A few documentation tweaks.
* fix page history with table prefix
* fix paging on history
* switch 'earliest' and 'latest' link order to fix 'prev' and 'next'
* use null where appropriate
* switch some messages to plaintext or wikitext
(somewhat experimental; currently needs memcached)
* Pretty up HTTP error output a bit (HTML instead of text/plain)
* Genericise DNS blacklist support a bit, func for Blitzed OPM
(not yet used)
* Handle attempt to move over self with a particular error message.
* Handle attempt to move page to invalid namespace or interwiki with a
particular error message.
* Don't offer to delete the target page if it's a self-move or illegal move!
* Replacing Namespace:: functions with NS_ constants
* Replacing make*Link() on strings with make*LinkObj() on Title objects
* Using more legible convenience methods on User and Title
* Start using a common Linker::commentBlock() to wrap the formatComment() bits in the surrounding formatting
* missing global $wgUser that produced a notice at hook call
* FIXME: sucess redirection for Special:Movepage pass through the parser, breaking the header relocation :-/
* Allow [[0]] to be renamed
* Fix the $wgRawHtml check so it actually works
* (bug 776) Old title as default for new title when moving pages [modified patch from guanaco]
currently which make it a dubious thing to try to do). Fix HTML for
error display on move. Add error class to style sheets. Fix error call
in protect. Remove dupe function that was moved from skin to output.
