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

140
141 == Compatibility ==
142
143 MediaWiki 1.16 requires PHP 5 (5.2 recommended). PHP 4 is no longer supported.
144
145 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
146 http://bugs.php.net/bug.php?id=34879
147 Upgrade affected systems to PHP 5.1 or higher.
148
149 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
150 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
151
152
153 == Upgrading ==
154
155 1.16 has several database changes since 1.15, and will not work without schema
156 updates.
157
158 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
159 ry, make sure that it is updated as well. Otherwise, errors may arise due to
160 database schema changes.
161
162 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
163 new database fields are filled with data.
164
165 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
166 changes are made, and there is a slightly higher chance that things could
167 break. Don't forget to always back up your database before upgrading!
168
169 See the file UPGRADE for more detailed upgrade instructions.
170
171
172 === Caveats ===
173
174 Some output, particularly involving user-supplied inline HTML, may not
175 produce 100% valid or well-formed XHTML output. Testers are welcome to
176 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
177 cases, but this is not recommended on live sites. (This must be set for
178 MathML to display properly in Mozilla.)
179
180 For notes on 1.15.x and older releases, see HISTORY.

183 === Online documentation ===
184
185 Documentation for both end-users and site administrators is currently being
186 built up on MediaWiki.org, and is covered under the GNU Free Documentation
187 License (except for pages that explicitly state that their contents are in
188 the public domain) :

193 === Mailing list ===
194
195 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
196 wikitech-l list:
197
198 http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
199
200 A low-traffic announcements-only list is also available:

203
204 It's highly recommended that you sign up for one of these lists if you're
205 going to run a public MediaWiki, so you can be notified of security fixes.
