Chad Horohoe 2f28d7dd70 Kill $wgArticle
This has been deprecated since 1.18, throwing warnings for over a
year and a half now, and nothing uses it anywhere in core or deployed
extensions.

No extensions in SVN seem to have this anymore (we must've cleaned
up well), and the only affected extensions in Git are:

- BlueSpiceExtensions
- DynamicPageList (commented, so shouldn't be a worry)
- SemanticPageMaker
- TwitterCards

If you're the author of one of these extensions or are feeling like
cleaning up ancient code, please get them fixed.

Security reminder: MediaWiki does not require PHP's register_globals. If you
have it on, turn it '''off''' if you can.
== MediaWiki 1.23 ==
THIS IS NOT A RELEASE YET
MediaWiki 1.23 is an alpha-quality branch and is not recommended for use in
production.
=== Configuration changes in 1.23 ===
=== New features in 1.23 ===
* ResourceLoader can utilize the Web Storage API to cache modules client-side.
Compared to the browser cache, caching in Web Storage allows ResourceLoader
to be more granular about evicting stale modules from the cache while
retaining the ability to retrieve multiple modules in a single HTTP request.
This capability can be enabled by setting $wgResourceLoaderStorageEnabled to
true. This feature is currently considered experimental and should only be
enabled with care.
=== Bug fixes in 1.23 ===
* (bug 41759) The "updated since last visit" markers (on history pages, recent
changes and watchlist) and the talk page message indicator are now correctly
updated when the user is viewing old revisions of pages, instead of always
acting as if the latest revision was being viewed.
=== API changes in 1.23 ===
=== Languages updated in 1.23===
MediaWiki supports over 350 languages. Many localisations are updated
regularly. Below only new and removed languages are listed, as well as
changes to languages because of Bugzilla reports.
=== Other changes in 1.23 ===
* The global variable $wgArticle has been removed after a lengthy deprecation
== Compatibility ==
MediaWiki 1.23 requires PHP 5.3.2 or later.
MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
support for them is somewhat less mature. There is experimental support for
Oracle.
The supported versions are:
* MySQL 5.0.2 or later
* PostgreSQL 8.3 or later
* SQLite 3.3.7 or later
* Oracle 9.0.1 or later
== Upgrading ==
1.23 has several database changes since 1.22, and will not work without schema
updates. Note that due to changes to some very large tables like the revision
table, the schema update may take quite long (minutes on a medium sized site,
many hours on a large site).
If upgrading from before 1.11, and you are using a wiki as a commons
repository, make sure that it is updated as well. Otherwise, errors may arise
due to database schema changes.
If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
new database fields are filled with data.
If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
with MediaWiki 1.21.
Don't forget to always back up your database before upgrading!
See the file UPGRADE for more detailed upgrade instructions.
For notes on 1.21.x and older releases, see HISTORY.
== Online documentation ==
Documentation for both end-users and site administrators is available on
MediaWiki.org, and is covered under the GNU Free Documentation License (except
for pages that explicitly state that their contents are in the public domain):
https://www.mediawiki.org/wiki/Documentation
== Mailing list ==
A mailing list is available for MediaWiki user support and discussion:
https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
A low-traffic announcements-only list is also available:
https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
It's highly recommended that you sign up for one of these lists if you're
going to run a public MediaWiki, so you can be notified of security fixes.
== IRC help ==
There's usually someone online in #mediawiki on irc.freenode.net.
