Localization update.

[lhc/web/wiklou.git] / RELEASE-NOTES

= MediaWiki release notes =

Security reminder: MediaWiki does not require PHP's register_globals
setting since version 1.2.0. If you have it on, turn it *off* if you can.

== MediaWiki 1.14 ==

THIS IS NOT A RELEASE YET

MediaWiki is now using a "continuous integration" development model with
quarterly snapshot releases. The latest development code is always kept
"ready to run", and in fact runs our own sites on Wikipedia.

Release branches will continue to receive security updates for about a year
from first release, but nonessential bugfixes and feature developments
will be made on the development trunk and appear in the next quarterly release.

Those wishing to use the latest code instead of a branch release can obtain
it from source control: http://www.mediawiki.org/wiki/Download_from_SVN

=== Configuration changes in 1.14 ===

* $wgExemptFromUserRobotsControl is an array of namespaces to be exempt from
  the effect of the new __INDEX__/__NOINDEX__ magic words.  (Default: null, ex-
  empt all content namespaces.)
* $wgForwardSearchUrl has been removed entirely. Documented setting since 1.4
  has been $wgSearchForwardUrl.
* (bug 15080) $wgOverrideSiteFeed has been added. Setting either
  $wgSiteFeed['rss'] or 'atom' to a URL will override the default Recent Changes
  feed that appears on all pages.
* $wgSQLiteDataDirMode has been introduced as the default directory mode for
  SQLite data directories on creation. Note this setting is separate from
  $wgDirectoryMode, which applies to all normal directories created by MediaWiki.
* $wgGroupsAddToSelf and $wgGroupsRemoveFromSelf now work more like
  $wgAddGroups and $wgRemoveGroups, where the user must belong to a specified
  group in order to add or remove those groups from themselves.
  Backwards compatibility is maintained.
* $wgRestrictDisplayTitle controls if the use of the {{DISPLAYTITLE}} magic
  word is restricted to titles equivalent to the actual page title. This
  is true per default, but can be set to false to allow any title.
* $wgSpamRegex may now be an array of multiple regular expressions.
* $wgAjaxSearch has been removed; use $wgEnableMWSuggest instead.
* Editing the MediaWiki namespace is now unconditionally restricted to people 
  with the editinterface right, configuring this in $wgNamespaceProtection 
  is not required.
* $wgAllowExternalImagesFrom may now be an array of multiple strings.
* Introduced $wgEnableImageWhitelist to toggle the on-wiki external image
  whitelist on or off.
* Added $wgRenderHashAppend to append some string to the parser cache and the
  sitenotice cache keys.

=== Migrated extensions ===
The following extensions are migrated into MediaWiki 1.14:

* Special:DeletedContributions to show deleted user contributions (was extension
  DeletedContributions)
* Special:Log/newusers recording new users (was extension Newuserlog)
* Special:LinkSearch to search for external links (was extension LinkSearch)
* RenderHash

=== New features in 1.14 ===

* New URL syntaxes for Special:ListUsers - 'Special:ListUsers/USER' and
  'Special:ListUsers/GROUP/USER', in addition to the older syntax
  'Special:ListUsers/GROUP' where GROUP is a valid group name.
* Configurable per-namespace and per-page notices for the edit form,
  respectively MediaWiki:Editnotice-# where # is the namespace number, and
  MediaWiki:Editnotice-#-PAGENAME where # is the page's namespace number and
  PAGENAME is the page name minus the namespace prefix.
* (bug 8068) New __INDEX__ and __NOINDEX__ magic words allow user control of
  search engine indexing on a per-article basis.
* Handheld stylesheet options
* Added 'DoEditSectionLink' hook as a cleaner unified version of the old
  'EditSectionLink' and 'EditSectionLinkForOther' hooks.  Note that the
  'EditSectionLinkForOther' hook has been removed, but 'EditSectionLink' is
  run in all cases instead, so extensions using the old hooks should still work
  if they ran roughly the same code for both hooks (as is almost certain).
* Signature (~~~~) "cleaning", i.e. template removal, can be disabled with
  $wgCleanSignatures=false
* Extensions can use the SkinBuildSidebar hook to modify the content of the
  sidebar and add custom portlets to it

  ables into into the output of Skin::makeVariablesScript

=== Languages updated in 1.14 ===

MediaWiki supports over 300 languages. Many localisations are updated
regularly. Below only new and removed languages are listed.

* Bakhtiari (bqi) (new)
* Fiji Hindi (Devanagari script) (hif-deva) (new)
* Krio (kri) (new)
* Lezghian (lez) (new)
* Laz (lzz) (new)
* Niuean (niu) (new)
* Oromo (om) (new)
* Plautdietsch (pdt) (new)
* Tarantino (roa-tara) (new)

== Compatibility ==

MediaWiki 1.14 requires PHP 5 (5.2 recommended). PHP 4 is no longer supported.

PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
http://bugs.php.net/bug.php?id=34879
Upgrade affected systems to PHP 5.1 or higher.

MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.


== Upgrading ==

1.14 has several database changes since 1.13, and will not work without schema
updates.

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, some major database
changes are made, and there is a slightly higher chance that things could
break. Don't forget to always back up your database before upgrading!

See the file UPGRADE for more detailed upgrade instructions.


=== Caveats ===

Some output, particularly involving user-supplied inline HTML, may not
produce 100% valid or well-formed XHTML output. Testers are welcome to
set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
cases, but this is not recommended on live sites. (This must be set for
MathML to display properly in Mozilla.)

For notes on 1.13.x and older releases, see HISTORY.


=== Online documentation ===

Documentation for both end-users and site administrators is currently being
built up 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) :

  http://www.mediawiki.org/wiki/Documentation


=== Mailing list ===

A MediaWiki-l mailing list has been set up distinct from the Wikipedia
wikitech-l list:

  http://lists.wikimedia.org/mailman/listinfo/mediawiki-l

A low-traffic announcements-only list is also available:

  http://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
