* allow interwiki {{subst:...}} using action=raw fetches
* Allowed non-MSIE browsers to access action=raw via the article alias. This is necessary to allow action=raw transclusion, since the only known URL is the article path, not the script path.
* Specify a user agent in wfGetHttp() fetches, when using curl.
* Added transcache table to tables.sql, it was in the updater but not there for some reason.
* Fixed transcache expiry, added option
* Allow interwiki transclusion outside the template namespace using leading colon syntax. Syntax is counterintuitive at times, e.g. to subst the wikipedia main page you would use {{subst::Wikipedia:Main_Page}} not {{subst:Wikipedia::Main_Page}}.
* Convert unnecessary URL escape codes in external links to their equivalent
character before doing anything with them. This prevents certain kinds of
spam filter evasion. (Parser.php only)
* 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.
* (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
more or less work for now.
* user_groups ur_group is now a short string key ('sysop' etc)
* groups table is gone
* user_rights table is gone
* Permissions for groups are for now set in $wgGroupPermissions.
An in-database management system could be re-added in the future
if it's really needed, but for now it's mostly just been screwing
things up.
* Group.php and Special:Groups are deprecated; will probably die.
* User group memberships are set explicitly through addGroup and
removeGroup methods instead of being re-saved on every change to
the user record.
Group keys are migrated from user_rights at upgrade time for older wikis.
The fields in prior 1.5alpha tables were too screwed up and will need to
manually have sysops re-assigned.
The Makesysop extension will need some minor tweaks.
dealing with moves and deletes of widely-linked pages.
The updaters should be fixed up to understand future versions without the
tables there without breaking upgrades.
The archive table now has an ar_text_id field which points at the
text record containing the deleted revision's text. Older archive
records containing self-contained text are still supported and
will be restored by adding a new revision.
For now, revision and page records are still removed on deletion,
but text records are left intact. This will keep block compression
and immutable alternate storage backends working relatively cleanly.
A rev_deleted flag field is reserved in revision for further future
changes but that won't happen in the 1.5 timeframe.
There is no longer a delete-on-join which was present in earlier
1.5 revisions, so deletion should work on MySQL 3.x again.
* Begin infrastructure for deleted-revision tag; add rev_deleted field, some
display support for it in history and contribs. Not yet used for deletions.
Run update.php or source maintenance/archives/patch-rev_deleted.sql
* This will allow the backend text storage to use different id numbers
* Revisions noting metadata changes can be added to history without duplicating text
(implemented for page move)
This changes the revision table schema and requires running update.php
or maintenance/archives/patch-rev_text_id.sql on existing test wikis.
PostgreSQL table defs are still not in sync, so not updated.
revision text is now stored separately and may be compressed.
This field is indexed which speeds up Special:Shortpages & Longpages.
Removed no longer used wfArticleIsStub().
