3 THIS IS NOT A RELEASE YET
5 MediaWiki 1.30 is an alpha-quality branch and is not recommended for use in
8 === MySQL version requirement in 1.30 ===
9 As of 1.30, MediaWiki now requires MySQL 5.5.8 or higher (see Compatibility
12 === Configuration changes in 1.30 ===
13 * The "C.UTF-8" locale should be used for $wgShellLocale, if available, to avoid
14 unexpected behavior when code uses locale-sensitive string comparisons. For
15 example, the Scribunto extension considers "bar" < "Foo" in most locales
16 since it ignores case.
17 * $wgShellLocale now affects LC_ALL rather than only LC_CTYPE. See
18 documentation of $wgShellLocale for details.
19 * $wgShellLocale is now applied for all requests. wfInitShellLocale() is
20 deprecated and a no-op, as it is no longer needed.
21 * $wgJobClasses may now specify callback functions as an alternative to plain
22 class names. This is intended for extensions that want control over the
23 instantiation of their jobs, to allow for proper dependency injection.
24 * $wgResourceModules may now specify callback functions as an alternative
25 to plain class names, using the 'factory' key in the module description
26 array. This allows dependency injection to be used for ResourceLoader modules.
27 * $wgExceptionHooks has been removed.
28 * (T45547) $wgUsePigLatinVariant added (off by default).
29 * (T152540) MediaWiki now supports a section ID escaping style that allows to display
30 non-Latin characters verbatim on many modern browsers. This is controlled by the
31 new configuration setting, $wgFragmentMode.
32 * $wgExperimentalHtmlIds is now deprecated and will be removed in a future version,
33 use $wgFragmentMode to migrate off it to a modern alternative.
34 * $wgExternalInterwikiFragmentMode was introduced to control how fragments in
35 sinterwikis going outside of current wiki farm are encoded.
36 * (T120333) Soft-deprecated the use of PHP extension 'mysql' in favor of 'mysqli'.
37 This PHP extension was deprecated in PHP 5.5 and removed in PHP 7.0. MediaWiki
38 auto-selects the 'mysqli' driver since MediaWiki 1.22, except if explicitly
39 requested through the configuration parameter $wgDBservers.
40 * $wgOOUIEditPage was removed, as it is now the default. This was documented as a
41 temporary variable during the migration period.
43 === New features in 1.30 ===
44 * (T37247) Output from Parser::parse() will now be wrapped in a div with
45 class="mw-parser-output" by default. This may be changed or disabled using
46 ParserOptions::setWrapOutputClass().
47 * Added 'ChangeTagsAllowedAdd' hook, enabling extensions to allow software-
48 specific tags to be added by users.
49 * Added a 'ParserOptionsRegister' hook to allow extensions to register
50 additional parser options.
51 * (T45547) Included Pig Latin, a language game in English, as a
52 LanguageConverter variant. This allows English-speaking developers
53 to develop and test LanguageConverter more easily. Pig Latin can be
54 enabled by setting $wgUsePigLatinVariant to true.
55 * Added RecentChangesPurgeRows hook to allow extensions to purge data that
56 depends on the recentchanges table.
57 * Added JS config values wgDiffOldId/wgDiffNewId to the output of diff pages.
58 * (T2424) Added direct unwatch links to entries in Special:Watchlist (if the
59 'watchlistunwatchlinks' preference option is enabled). With JavaScript
60 enabled, these links toggle so the user can also re-watch pages that have
62 * Added $wgParserTestMediaHandlers, where mock media handlers can be passed to
63 MediaHandlerFactory for parser tests.
65 === External library changes in 1.30 ===
67 ==== Upgraded external libraries ====
68 * mediawiki/mediawiki-codesniffer updated to 0.8.1.
69 * wikimedia/composer-merge-plugin updated to 1.4.1.

82 === Action API changes in 1.30 ===
83 * (T37247) action=parse output will be wrapped in a div with
84 class="mw-parser-output" by default. This may be changed or disabled using
85 the new 'wrapoutputclass' parameter.
86 * When errorformat is not 'bc', abort reasons from action=login will be
87 formatted as specified by the error formatter parameters.
88 * action=compare can now handle arbitrary text, deleted revisions, and
89 returning users and edit comments.
90 * (T164106) The 'rvdifftotext', 'rvdifftotextpst', 'rvdiffto',
91 'rvexpandtemplates', 'rvgeneratexml', 'rvparse', and 'rvprop=parsetree'
92 parameters to prop=revisions are deprecated, as are the similarly named
93 parameters to prop=deletedrevisions, list=allrevisions, and
94 list=alldeletedrevisions. Use action=compare, action=parse, or
95 action=expandtemplates instead.
97 === Action API internal changes in 1.30 ===
98 * ApiBase::getDescriptionMessage() and the "apihelp-*-description" messages are
99 deprecated. The existing message should be split between "apihelp-*-summary"
100 and "apihelp-*-extended-description".
101 * (T123931) Individual values of multi-valued parameters can now be marked as
104 === Languages updated in 1.30 ===

113 ==== Pig Latin added ====
114 * (T45547) Added Pig Latin, a made-up English variant (en-x-piglatin),
115 for easier variant development and testing. Disabled by default. It can be
116 enabled by setting $wgUsePigLatinVariant to true.
118 === Other changes in 1.30 ===
119 * The use of an associative array for $wgProxyList, where the IP address is in
120 the key instead of the value, is deprecated (e.g. [ '127.0.0.1' => 'value' ]).

135 BagOStuff::makeGlobalKey() should be used instead.
136 * (T146304) Preprocessor handling of LanguageConverter markup has been improved.
137 As a result of the new uniform handling, '-{' may need to be escaped
138 (for example, as '-<nowiki/>{') where it occurs inside template arguments
140 * (T163966) Page moves are now counted as edits for the purposes of
141 autopromotion, i.e., they increment the user_editcount field in the database.
142 * Two new hooks, LogEventsListLineEnding and NewPagesLineEnding, were added for
143 manipulating Special:Log and Special:NewPages lines.
144 * The OldChangesListRecentChangesLine, EnhancedChangesListModifyLineData,
145 PageHistoryLineEnding, ContributionsLineEnding and DeletedContributionsLineEnding
146 hooks have an additional parameter, for manipulating HTML data attributes of

149 * (T130632) The OutputPage::enableTOC() method was removed.
150 * WikiPage::getParserOutput() will now throw an exception if passed

159 are all deprecated. The main ParserCache instance should be obtained from
160 MediaWikiServices instead. Access to the underlying BagOStuff is possible
161 through the new ParserCache::getCacheStorage() method.
162 * .mw-ui-constructive CSS class (deprecated in 1.27) was removed.
163 * Sanitizer::escapeId() was deprecated, use escapeIdForAttribute(),

167 * Second parameter to Sanitizer::escapeIdReferenceList() ($options) now does
168 nothing and is deprecated.

192 PRIMARY KEYs for increased maintainability: categorylinks, imagelinks, iwlinks,

194 templatelinks, text, transcache, user_former_groups, user_properties.
197 MediaWiki 1.30 requires PHP 5.5.9 or later. There is experimental support for
200 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
201 but support for them is somewhat less mature. There is experimental support for
202 Oracle and Microsoft SQL Server.
204 The supported versions are:
206 * MySQL 5.5.8 or later
207 * PostgreSQL 8.3 or later
208 * SQLite 3.3.7 or later
209 * Oracle 9.0.1 or later
210 * Microsoft SQL Server 2005 (9.00.1399)
213 1.30 has several database changes since 1.29, and will not work without schema
214 updates. Note that due to changes to some very large tables like the revision
215 table, the schema update may take a long time (minutes on a medium sized site,
216 many hours on a large site).
218 Don't forget to always back up your database before upgrading!
220 See the file UPGRADE for more detailed upgrade instructions, including
221 important information when upgrading from versions prior to 1.11.
