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

135
136 == Compatibility ==
137
138 MediaWiki 1.15 requires PHP 5 (5.2 recommended). PHP 4 is no longer supported.
139
140 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
141 http://bugs.php.net/bug.php?id=34879
142 Upgrade affected systems to PHP 5.1 or higher.
143
144 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
145 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
146
147
148 == Upgrading ==
149
150 1.15 has several database changes since 1.14, and will not work without schema
151 updates.
152
153 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
154 ry, make sure that it is updated as well. Otherwise, errors may arise due to
155 database schema changes.
156
157 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
158 new database fields are filled with data.
159
160 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
161 changes are made, and there is a slightly higher chance that things could
162 break. Don't forget to always back up your database before upgrading!
163
164 See the file UPGRADE for more detailed upgrade instructions.
165
166
167 === Caveats ===
168
169 Some output, particularly involving user-supplied inline HTML, may not
170 produce 100% valid or well-formed XHTML output. Testers are welcome to
171 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
172 cases, but this is not recommended on live sites. (This must be set for
173 MathML to display properly in Mozilla.)
174
175 For notes on 1.14.x and older releases, see HISTORY.

177
178 === Online documentation ===
179
180 Documentation for both end-users and site administrators is currently being
181 built up on MediaWiki.org, and is covered under the GNU Free Documentation
182 License (except for pages that explicitly state that their contents are in
183 the public domain) :

186
187
188 === Mailing list ===
189
190 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
191 wikitech-l list:
192
193 http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
194
195 A low-traffic announcements-only list is also available:
196
197 http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
198
199 It's highly recommended that you sign up for one of these lists if you're
200 going to run a public MediaWiki, so you can be notified of security fixes.
