-----BEGIN PGP SIGNED MESSAGE-----
MediaWiki 1.4beta1 is an experimental release, to help flush out
remaining major problems in the code prior to a final public 1.4.0
release. It is not recommended to use this beta on a public site unless
you're familiar with MediaWiki innards and are willing and able to help
diagnose and fix problems that come up.
=== New features ===
* 'Recentchanges Patrol' to mark new edits that haven't yet been viewed.
* New, searchable deletion/upload/protection logs
* Image gallery generation (Special:Newimages and <gallery> tag)
* SVG rasterization support (requires external support)
* Users can select from the available localizations to override the
default user interface language.
* Traditional/Simplified Chinese conversion support
=== Installation and compatibility ===
* The default MonoBook theme now works with PHP 5.0
* Installation on systems with PHP's safe mode or other oddities
should work more reliably, as MonoBook no longer needs to
create a compiled template file for the wiki to run.
* A table prefix may be specified, to avoid conflicts with other
web applications forced to share a database.
* More thorough UTF-8 input validation; fixes non-ASCII uploaded
filenames from Safari.
* Command-line database upgrade script.
=== Customizability ===
* Default user options can now be overridden in LocalSettings.
* Skins system more modular: templates and CSS are now in /skins/
New skins can be dropped into this directory and used immediately.
* More extension hooks have been added.
* Authentication plugin hook.
* More internal code documentation, generated with phpdoc:
=== Optimization ===
* For many operations, MediaWiki 1.4 should run faster and use
less memory than MediaWiki 1.3. Page rendering is up to twice
as fast. (Use a PHP accelerator such as Turck MMCache for best
results with any PHP application, though!)
* The parser cache no longer requires memcached, and is enabled
by default. This avoids a lot of re-rendering of pages that
have been shown recently, greatly speeding longer page views.
* Support for compiled PHP modules to speed up page diff and
Unicode validation/normalization. (Requires ability to compile
and load PHP extensions).
=== What isn't ready yet ===
* A new user/groups permissions scheme has been held back to 1.5.
* An experimental SOAP interface will be made available as an extension
* PostgreSQL support is largely working, but search and installer
support are not complete. These are being actively worked on
and should come in later betas.
* E-mail notification of watched page changes and verification of
user-submitted e-mail addresses is not yet included. If updates
are available, this may make it into later betas.
* Log pages are not automatically imported into the new log table
at upgrade time. A script to import old text log entries is
incomplete, but may be available by the time 1.4 finishes.
* UI messages may be broken in Latin-1 mode in this release due to some
minor breakage in the language selection module.
