8 THIS IS NOT A RELEASE YET
9
10 MediaWiki is now using a "continuous integration" development model with
11 quarterly snapshot releases. The latest development code is always kept
12 "ready to run", and in fact runs our own sites on Wikipedia.
13
14 Release branches will continue to receive security updates for about a year
15 from first release, but nonessential bugfixes and feature developments
16 will be made on the development trunk and appear in the next quarterly release.
17
18 Those wishing to use the latest code instead of a branch release can obtain
19 it from source control: http://www.mediawiki.org/wiki/Download_from_SVN
20
21 === Configuration changes in 1.12 ===
22 * Marking edits as bot edits with Special:Contributions?bot=1 now requires the
23 markbotedit permission, rather than the rollback permission previously used.
24 This permission is assigned by default to the sysop group.
25 * MediaWiki now checks if serialized files are out of date. New configuration
26 variable $wgCheckSerialized can be set to false to enable old behavior (i.e.
27 to not check and assume they are always up to date)
28
29 === New features in 1.12 ===
30 * (bug 10735) Add a warning for non-descriptive filenames at Special:Upload
31 * Add {{filepath:}} parser function to get full path to an uploaded file,
32 complementing {{fullurl:}} for pages.
33 * (bug 11136) If using Postgres, search path is explicitly set if wgDBmwschema
34 is not set to 'mediawiki', allowing multiple mediawiki instances per user.
35 * (bug 11151) Add descriptive <title> to revision history page
36 * (bug 5412) Add feed links for the site to all pages
37 * (bug 11353) Add ability to retrieve raw section content via action=raw

39 deleted file
40 * On SkinTemplate based skins (like MonoBook), omit confusing "edit"/"view
41 source" tab entirely if the page doesn't exist and the user isn't allowed to
42 create it
43 * Clarify instructions given when an exception is thrown
44 * AuthPlugin added strictUserAuth() method to allow per-user override
45 of the strict() authentication behavior.

47 against the previous revision, whether currently deleted or live.
48 * Added tooltips for the "Go" and "Search" buttons

50 * isValidEmailAddr hook added to User method of that name, to allow, e.g., re-
51 stricting e-mail addresses to a specific domain
52 * Removed "Clear" link in watchlist editor tools, as people were afraid to
53 click it. Existing clear links will fall back to the raw editor, which is
54 very easy to clear your watchlist with.

56 on Special:Newpages
57 * LogLine hook added to allow formatting custom entries in Special:Log.

70 * Support for Hebrew calendar
71 * Support for Hebrew numerals in dates and times

73 [[MediaWiki:Signature-anon]]
74 * Signatures for anonymous users link to Special:Contributions page rather than
75 user page
76 * Added --override switch for disabled pages in updateSpecialPages.php
77 * Provide a unique message (ipb_blocked_as_range) if unblock of a single IP
78 fails
79 because it is part of a blocked range.
80 * (bug 3973) Use a separate message for the email content when an account is
81 created by another user
82 * dumpTextPass.php can spawn fetchText.php as a subprocess, which should restart
83 cleanly if database connections fail unpleasantly.
84 * (bug 12028) Add Special:Listbots as shortcut for Special:Listusers/bot
85 * (bug 9633) Add a predefined list of delete reasons to the deletion form

90 * Only show most recent 5000 revisions on Special:Undelete by default. Accept
91 limit and offset parameters. Undelete with no revisions selected still
92 undeletes all revisions, regardless of how many are displayed.

218
219 == Parser changes in 1.12 ==
220
221 The parser pass order has changed from
222
223 * Extension tag strip and render
224 * HTML normalisation and security
225 * Template expansion
226 * Main section...
227
228 to
229
230 * Template and extension tag parse to intermediate representation
231 * Template expansion and extension rendering
232 * HTML normalisation and security
233 * Main section...
234
235 The main effect of this for the user is that the rules for uncovered syntax
236 have changed.
237
238 Uncovered main-pass syntax, such as HTML tags, are now generally valid, whereas
239 previously in some cases they were escaped. For example, you could have "<ta" in
240 one template, and "ble>" in another template, and put them together to make a
241 valid <table> tag. Previously the result would have been "&lt;table&gt;".
242
243 Uncovered preprocessor syntax is generally not recognised. For example, if you
244 have "{{a" in Template:A and "b}}" in Template:B, then "{{a}}{{b}}" will be
245 converted to a literal "{{ab}}" rather than the contents of Template:Ab. This
246 was the case previously in HTML output mode, and is now uniformly the case in
247 the other modes as well. HTML-style comments uncovered by template expansion
248 will not be recognised by the preprocessor and hence will not prevent template
249 expansion within them, but they will be stripped by the following HTML security
250 pass.
251
252 The rules for template expansion during message transformation were
253 counterintuitive, mostly accidental and buggy. There are a few small changes in
254 this version: for example, templates with dynamic names, as in "{{ {{a}} }}",
255 are fully expanded as they are in HTML mode, whereas previously only the inner
256 template was expanded. I'd like to make some larger breaking changes to message
257 transformation, after a review of typical use cases.
258
259 The header identification routines for section edit and for numbering section
260 edit links have been merged. This removes a significant failure mode and fixes a
261 whole category of bugs (tracked by bug #4899). Wikitext headings uncovered by
262 template expansion or comment removal will still be rendered into a heading tag,
263 and will get an entry in the TOC, but will not have a section edit link.
264 HTML-style headings will also not have a section edit link. Valid wikitext
265 headings present in the template source text will get a template section edit
266 link. This is a major break from previous behaviour, but I believe the effects
267 are almost entirely beneficial.
268
269 The main motivation for making these changes was performance. The new two-pass
270 preprocessor can skip "dead branches" in template expansion, such as unfollowed
271 #switch cases and unused defaults for template arguments. This provides a
272 significant performance improvement in template-heavy test cases taken from
273 Wikipedia. Parser function hooks can participate in this performance improvement
274 by using the new SFH_OBJECT_ARGS flag during registration.
275
276 The pre-expand include size limit has been removed, since there's no efficient
277 way to calculate such a figure, and it would now be meaningless for performance
278 anyway. The "preprocessor node count" takes its place, with a generous default
279 limit.
280
281 The context in which XML-style extension tags are called has changed, so
282 extensions which make use of the parser state may need compatibility changes.
283

485 == Compatibility ==
486
487 MediaWiki 1.12 requires PHP 5 (5.1 recommended). PHP 4 is no longer supported.
488
489 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
490 http://bugs.php.net/bug.php?id=34879
491 Upgrade affected systems to PHP 5.1 or higher.
492
493 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
494 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
495
496
497 == Upgrading ==
498
499 1.12 has several database changes since 1.11, and will not work without schema
500 updates.
501
502 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
503 new database fields are filled with data.
504
505 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
506 changes are made, and there is a slightly higher chance that things could
507 break. Don't forget to always back up your database before upgrading!
508
509 See the file UPGRADE for more detailed upgrade instructions.

512 === Caveats ===
513
514 Some output, particularly involving user-supplied inline HTML, may not
515 produce 100% valid or well-formed XHTML output. Testers are welcome to
516 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
517 cases, but this is not recommended on live sites. (This must be set for
518 MathML to display properly in Mozilla.)

523 === Online documentation ===
524
525 Documentation for both end-users and site administrators is currently being
526 built up on MediaWiki.org, and is covered under the GNU Free Documentation
527 License (except for pages that explicitly state that their contents are in
528 the public domain) :

533 === Mailing list ===
534
535 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
536 wikitech-l list:
537
538 http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
539
540 A low-traffic announcements-only list is also available:
541
542 http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
543
544 It's highly recommended that you sign up for one of these lists if you're
545 going to run a public MediaWiki, so you can be notified of security fixes.
