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

7
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 development happen
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

40 == Compatibility ==
41
42 Older PHP 4.2 and 4.1 releases are no longer supported; PHP 4 users must
43 upgrade to 4.3 or later.
44
45 MediaWiki 1.6 is the last major version to support PHP 4; future versions
46 will require PHP 5.
47
48 MySQL 3.23.x is longer supported; some older hosts may need to upgrade.
49 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
50
51
52 == Upgrading ==
53
54 Several changes to the database have been made from 1.5; these are relatively
55 minor but do require that the update process be run before the new code will
56 work properly:
57
58 * A new "templatelinks" table tracks template inclusions.
59 * A new "externallinks" table tracks URL links; this can be used by a
60 mass spam-cleanup tool in the SpamBlacklist extension.
61 * A new "jobs" table stores a queue of pages to update in the background; this
62 is used to update links in including pages when templates are edited.
63
64 To ensure that these tables are filled with data, run refreshLinks.php after
65 the upgrade.
66
67
68 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
69 changes are made, and there is a slightly higher chance that things could
70 break. Don't forget to always back up your database before upgrading!
71
72 See the file UPGRADE for more detailed upgrade instructions.

76 === Caveats ===
77
78 Some output, particularly involving user-supplied inline HTML, may not
79 produce 100% valid or well-formed XHTML output. Testers are welcome to
80 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
81 cases, but this is not recommended on live sites. (This must be set for
82 MathML to display properly in Mozilla.)

97 === Mailing list ===
98
99 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
100 wikitech-l list:
101
102 http://mail.wikimedia.org/mailman/listinfo/mediawiki-l
103
104 A low-traffic announcements-only list is also available:

107
108 It's highly recommended that you sign up for one of these lists if you're
109 going to run a public MediaWiki, so you can be notified of security fixes.
