This is a testing preview release, being put out mainly to aid testers in
|
||||
finding installation bugs and other major problems. It is strongly recommended
|
||||
NOT to run a live production web site on this alpha release.

|
||||
=== Big changes ===
|
||||
|
||||
Schema:
|
||||
The core table schema has changed significantly. This should make better
|
||||
use of the database's cache and disk I/O, and make significantly speed up
|
||||
rename and delete operations on pages with very long edit histories.
|
||||
|
||||
Unfortunately this does mean upgrading a wiki of size from 1.4 will require
|
||||
some downtime for the schema restructuring, but future storage backend
|
||||
changes should be able to integrate into the new system more easily.
|
||||
|
||||
Permalinks:
|
||||
The current revision of a page now has a permanent 'oldid' number assigned
|
||||
immediately, and the id numbers are now preserved across deletion/undeletion.
|
||||
A permanent reference to the current revision of a page is now just a matter
|
||||
of going to the 'history' tab and copying the first link in the list.
|
||||
|
||||
Page move log:
|
||||
Renames of pages are now recorded in Special:Log and the page history.
|
||||
A handy revert link is available from the log for sysops.
|
||||
|
||||
Editing diff:
|
||||
Ever lost track of what you'd done so far during an edit? A 'Show diff'
|
||||
button on the edit page now makes it easy to remember.
|
||||
|
||||
Uploads:
|
||||
It's now possible to specify the final filename of an upload distinct
|
||||
from the original filename on your disk.
|
||||
|
||||
An image link for a missing file will now take you straight to the upload page.
|
||||
|
||||
More metadata is pre-extracted from uploaded images, which will ease pressure
|
||||
on disk or NFS volumes used to store images. EXIF metadata is displayed on
|
||||
the image description page if PHP is configured with the necessary module.
|
||||
|
||||
User accounts:
|
||||
There are some changes to the user permissions system, with assignable
|
||||
groups. This is still somewhat in flux; do not rely on the present system
|
||||
that you see in this alpha to still be there.
|
||||
|
||||
E-mail:
|
||||
User-to-user e-mail can now be restricted to require a mail-back confirmation
|
||||
first to reduce potential for abuse with false addresses.
|
||||
|
||||
Updates to user talk pages and watchlist entries can optionally send e-mail
|
||||
notifications.
|
||||
|
||||
External hooks:
|
||||
A somewhat experimental interface for hooking in an external editor
|
||||
application is included. This may not be on by default in final release,
|
||||
depending on support.
|
||||
|
||||
And...
|
||||
A bunch of stuff we forgot to mention.
|
||||
|
||||
|
||||
=== What's gone? ===
|
||||
|
||||
Latin-1:
|
||||
Wikis must now be encoded in Unicode UTF-8; this has been the default for
|
||||
some time, but some languages could optionally be installed in Latin-1 mode.
|
||||
This is no longer supported.
|
||||
|
||||
MySQL 3.x:
|
||||
Some optimization hacks for MySQL 3.x have been removed as part of the schema
|
||||
clean-up (specifically, the inverse_timestamp fields). MediaWiki 1.5 should
|
||||
still run, but wikis of significant size should very seriously consider
|
||||
upgrading to a more modern release. MySQL 3.x support will probably be
|
||||
entirely dropped in the next major release later this year.
|
||||
|
||||
Special:Maintenance
|
||||
These tools were, ironically enough, not really maintained. This special
|
||||
page has been removed; insofar as some of its pieces were useful and haven't
|
||||
already been supplanted by other special pages they should be rewritten in
|
||||
an efficient and safe manner in the future.
|
||||
|
||||
|
||||
=== What's still waiting? ===
|
||||
|
||||
These things should be fixed by the time 1.5.0 final is released:
|
||||
|
||||
Upgrade:
|
||||
Wikis in Latin-1 encoding are no longer supported; only Unicode UTF-8.
|
||||
A new option $wgLegacyEncoding is provided to allow on-the-fly recoding of
|
||||
old page text entries, but other metadata fields (titles, comments etc) need
|
||||
to be pre-converted. The upgrade process does not yet fully automate this.
|
||||
|
||||
In general the upgrade from 1.4 to 1.5 schema has not been tested for all
|
||||
cases, and there may be problems.
|
||||
|
||||
Backups:
|
||||
The text entries of deleted pages are no longer removed from the main
|
||||
text table on deletion. If you provide public backup dumps of your databases,
|
||||
you will probably want to use the new XML-format dump generator... but
|
||||
this hasn't been finished yet.
|
||||
|
||||
PostgreSQL:
|
||||
The table definitions for PostgreSQL install are out of date, and patches
|
||||
to support PostgreSQL from the main installer are still pending.
|
||||
|
||||
MySQL 4.1+:
|
||||
Proper charset encoding / collation configuration for installs on MySQL 4.1
|
||||
and higher still needs to be fiddled with. Some bits may fail on the UTF-8
|
||||
setting due to some long field keys.
|
||||
|
||||
Authentication plugin fixes:
|
||||
The AuthPlugin interface needs some improvements to work better with LDAP,
|
||||
HTTP basic auth, and other such environments. Some patches are pending.
|
||||
|
||||
|
||||
=== Smaller changes ===

== Version Enotif+Eauthent EN+EA v2.00/CVS, 14.12.2004 ==
|
||||
written by Thomas Gries, Berlin and Markus Arndt, Munich
|
||||
|
||||
Executive summary for the impatient reader:
|
||||
|
||||
Enotif adds e-mail notification to MediaWiki and sends e-mails
|
||||
to watching users when a watch-listed page or user_talk page is changed
|
||||
http://bugzilla.wikipedia.org/show_bug.cgi?id=454
|
||||
Visit the complete documentation on http://meta.wikipedia.org/Enotif
|
||||
|
||||
Eauthent is a mechanism to use a temporary one-time password cycle
|
||||
to check whether the email address a user has entered is a valid one.
|
||||
http://bugzilla.wikipedia.org/show_bug.cgi?id=866
|
||||
Visit the complete documentation on http://meta.wikipedia.org/Eauthent
|
||||
|
||||
The current patch has only been checked for (see DefaultSettings.php):
|
||||
|
||||
- php mail()
|
||||
( = not using PEAR:Mail() module --- I do not know anyone who uses that)
|
||||
$wgSMTP = false;
|
||||
- MySQL database
|
||||
( = not using PostgreSQL --- I do not know anyone who uses that)
|
||||
$wgDBtype = "mysql";
|
||||
$wgSearchType = "MyISAM";
|
||||
|
||||
- STILL TODO:
|
||||
NEW (newpageletter) and CORR (minoreditletter) markers needs
|
||||
corresponding "spacers"
|
||||
|
||||
- table user_newtalk dropped; changes on usertalk pages and their
|
||||
notifications are now fully handled via existing table watchlist
|
||||
The user interface and behavious is unchanged to previous version.
|
||||
- updaters.inc for compatibility with older mediawiki tables:
|
||||
the conversion script converts existing user_newtalk entries
|
||||
watchlist table entries
|
||||
(user_newtalk) id ==> (watchlist) NS_USER_TALK:namefromId(id) timestamp=1
|
||||
- minor bug fixes:
|
||||
updated marker now correctly shown on watchlist page
|
||||
watching users number display with enhanced RC view + RCUseModStyle
|
||||
- wfUrlencode() instead of rawurlencode() in enotif mails
|
||||
- duplicate enotif code moved from UserTalkUpdate.php and
|
||||
merged into UserMailer.php and using usermailer() solely
|
||||
- fixed an enotif mail text error for user names with spaces
|
||||
- fixed missing part for suppressing watching user number
|
||||
|
||||
v1.36:
|
||||
magic watchlist shows and counts now only the content page, notwithstanding
|
||||
the content and talk page are stored separately in watchlist.
|
||||
* bug fixed: rawurlencode for pagetitles in enotif mails
|
||||
* bug fixed: link to userpages of anonymous user are correct now
|
||||
|
||||
* Enotif v1.34
|
||||
bugs fixed regarding missing $oldid parameter
|
||||
|
||||
* v1.33
|
||||
* Details:
|
||||
Implements almost all enotif options as user preferences.
|
||||
These are only shown on the user preference page, if they are globally
|
||||
enabled by the corresponding admin option in DefaultSettings.php.
|
||||
Added admin feature to let enotifs appear to come from the page editor.
|
||||
This facilitates automatic mail sorting and anti-spam filtering; feature was
|
||||
originally proposed by Nick Triantos, thank you !
|
||||
Page editor's email address is however only shown, if this user enabled
|
||||
the option "reveal my email address" in user preferences. Otherwise,
|
||||
the enotifs appear to come from WikiAdmin as usual (tricky to program,
|
||||
but simply trust the algorithm. or look into UserMailer.php and
|
||||
UserTalkPage.php).
|
||||
|
||||
* Changes from previous enotif versions
|
||||
* v1.31 is an improved version with many security and also cosmetic changes
|
||||
applied after two first reviews by Brion Vibber. v1.31 is basically the same as
|
||||
the older Enotif v1.30 and v1.22 versions.
|
||||
|
||||
Added UseMod style for recent changes view so that only the most recent
|
||||
change of any page is listed. The (diff) and (hist) still allow to retrieve the
|
||||
older versions at users' discretion, but the RC view is much cleaner for
|
||||
trusted environments such as medium-size companies or family wikis.
|
||||
|
||||
* Enotif v1.30 redesign after review by Brion Vibber 25.10.2003
|
||||
|
||||
* v1.22 "updated (since my last visit)" also shown for users without stored
|
||||
email address in preferences, so that they can see, what watched pages
|
||||
have changed.
|
||||
* show "updated (since my last visit)" markers in RC, history and watchlist
|
||||
* Systemvariables to suppress updated marker in all views
|
||||
* show number of watching users in RC and on bottom of articles in
|
||||
classic skin and in monobook skin
|
||||
* Systemvariables in DefaultSettings.php to enable or disable features
|
||||
* v1.21 now suppresses displaying the marker "updated (since my last visit)"
|
||||
in recent changes view for the older (already visited) versions of watched
|
||||
pages - i.e. page versions before the enotif was sent do not bear that
|
||||
marker any longer.
|
||||
* enotif mails come with a link to the diff view between current and last
|
||||
visited version of the watching user.
|
||||
*database structure is changed automatically when installing via the
|
||||
recommended way (starting index.php and re-using the old database name).
|
||||
run php /maintenance/update.php
|
||||
OR see /maintenance/archives/patch-email-notification.sql and apply the
|
||||
command
|
||||
ALTER TABLE watchlist
|
||||
ADD (wl_notificationtimestamp varchar(14) binary NOT NULL default '0');
|
||||
manually to your database, which does not harm the non notification versions
|
||||
|
||||
*adding a page x to the watchlist does automatically add a watch
|
||||
for the accompanying talk_page talk:x and vice versa;
|
||||
|
||||
== MediaWiki 1.4 BETA ==
|
||||
|
||||
[Not everything is 100% working in beta yet, the installer needs fixes still.]
|
||||
|
||||

|
||||

|
||||

|
||||
