[lhc/web/wiklou.git] / RELEASE-NOTES-1.30
1 == MediaWiki 1.30 ==
2
3 THIS IS NOT A RELEASE YET
4
5 MediaWiki 1.30 is an alpha-quality branch and is not recommended for use in
6 production.
7
8 === MySQL version requirement in 1.30 ===
9 As of 1.30, MediaWiki now requires MySQL 5.5.8 or higher (see Compatibility
10 section).
11
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
37 === New features in 1.30 ===
38 * (T37247) Output from Parser::parse() will now be wrapped in a div with
39 class="mw-parser-output" by default. This may be changed or disabled using
40 ParserOptions::setWrapOutputClass().
41 * Added 'ChangeTagsAllowedAdd' hook, enabling extensions to allow software-
42 specific tags to be added by users.
43 * Added a 'ParserOptionsRegister' hook to allow extensions to register
44 additional parser options.
45 * (T45547) Included Pig Latin, a language game in English, as a
46 LanguageConverter variant. This allows English-speaking developers
47 to develop and test LanguageConverter more easily. Pig Latin can be
48 enabled by setting $wgUsePigLatinVariant to true.
49 * Added RecentChangesPurgeRows hook to allow extensions to purge data that
50 depends on the recentchanges table.
51 * Added JS config values wgDiffOldId/wgDiffNewId to the output of diff pages.
52 * (T2424) Added direct unwatch links to entries in Special:Watchlist (if the
53 'watchlistunwatchlinks' preference option is enabled). With JavaScript
54 enabled, these links toggle so the user can also re-watch pages that have
55 just been unwatched.
56 * Added $wgParserTestMediaHandlers, where mock media handlers can be passed to
57 MediaHandlerFactory for parser tests.
58
59 === Languages updated in 1.30 ===
60
61 * Support for kbp (Kabɩyɛ / Kabiyè) was added.
62 * Support for skr (Saraiki, سرائیکی) was added.

78 * (T151633) Ordered list items use now Devanagari digits in Nepalese
79 (thanks to Sfic)
80
81 === Action API changes in 1.30 ===
82 * (T37247) action=parse output will be wrapped in a div with
83 class="mw-parser-output" by default. This may be changed or disabled using
84 the new 'wrapoutputclass' parameter.
85 * When errorformat is not 'bc', abort reasons from action=login will be
86 formatted as specified by the error formatter parameters.
87 * action=compare can now handle arbitrary text, deleted revisions, and
88 returning users and edit comments.
89 * (T164106) The 'rvdifftotext', 'rvdifftotextpst', 'rvdiffto',
90 'rvexpandtemplates', 'rvgeneratexml', 'rvparse', and 'rvprop=parsetree'
91 parameters to prop=revisions are deprecated, as are the similarly named
92 parameters to prop=deletedrevisions, list=allrevisions, and
93 list=alldeletedrevisions. Use action=compare, action=parse, or
94 action=expandtemplates instead.
95
96 === Action API internal changes in 1.30 ===
97 * ApiBase::getDescriptionMessage() and the "apihelp-*-description" messages are
98 deprecated. The existing message should be split between "apihelp-*-summary"
99 and "apihelp-*-extended-description".
100 * (T123931) Individual values of multi-valued parameters can now be marked as
101 deprecated.
102
103 === Languages updated in 1.30 ===
104 MediaWiki supports over 350 languages. Many localisations are updated
105 regularly. Below only new and removed languages are listed, as well as
106 changes to languages because of Phabricator reports.
107
108 * …
109
110 ==== Pig Latin added ====
111 * (T45547) Added Pig Latin, a made-up English variant (en-x-piglatin),
112 for easier variant development and testing. Disabled by default. It can be
113 enabled by setting $wgUsePigLatinVariant to true.
114
115 === Other changes in 1.30 ===
116 * The use of an associative array for $wgProxyList, where the IP address is in
117 the key instead of the value, is deprecated (e.g. [ '127.0.0.1' => 'value' ]).
118 Please convert these arrays to indexed/sequential ones (e.g. [ '127.0.0.1' ]).
119 * mw.user.bucket (deprecated in 1.23) was removed.
120 * LoadBalancer::getServerInfo() and LoadBalancer::setServerInfo() are
121 deprecated. There are no known callers.
122 * File::getStreamHeaders() was deprecated.
123 * MediaHandler::getStreamHeaders() was deprecated.
124 * Title::canTalk() was deprecated. The new Title::canHaveTalkPage() should be
125 used instead.
126 * MWNamespace::canTalk() was deprecated. The new MWNamespace::hasTalkNamespace()
127 should be used instead.
128 * The ExtractThumbParameters hook (deprecated in 1.21) was removed.
129 * The OutputPage::addParserOutputNoText and ::getHeadLinks methods (both
130 deprecated in 1.24) were removed.
131 * wfMemcKey() and wfGlobalCacheKey() were deprecated. BagOStuff::makeKey() and
132 BagOStuff::makeGlobalKey() should be used instead.
133 * (T146304) Preprocessor handling of LanguageConverter markup has been improved.
134 As a result of the new uniform handling, '-{' may need to be escaped
135 (for example, as '-<nowiki/>{') where it occurs inside template arguments
136 or wikilinks.
137 * (T163966) Page moves are now counted as edits for the purposes of
138 autopromotion, i.e., they increment the user_editcount field in the database.
139 * Two new hooks, LogEventsListLineEnding and NewPagesLineEnding, were added for
140 manipulating Special:Log and Special:NewPages lines.
141 * The OldChangesListRecentChangesLine, EnhancedChangesListModifyLineData,
142 PageHistoryLineEnding, ContributionsLineEnding and DeletedContributionsLineEnding
143 hooks have an additional parameter, for manipulating HTML data attributes of
144 RC/history lines. EnhancedChangesListModifyBlockLineData can do that via the
145 $data['attribs'] subarray.
146 * (T130632) The OutputPage::enableTOC() method was removed.
147 * WikiPage::getParserOutput() will now throw an exception if passed
148 ParserOptions that would pollute the parser cache. Callers should use
149 WikiPage::makeParserOptions() to create the ParserOptions object and only
150 change options that affect the parser cache key.
151 * Article::viewRedirect() is deprecated.
152 * DeprecatedGlobal no longer supports passing in a direct value, it requires a
153 callable factory function or a class name.
154 * The $parserMemc global, wfGetParserCacheStorage(), and ParserCache::singleton()
155 are all deprecated. The main ParserCache instance should be obtained from
156 MediaWikiServices instead. Access to the underlying BagOStuff is possible
157 through the new ParserCache::getCacheStorage() method.
158 * .mw-ui-constructive CSS class (deprecated in 1.27) was removed.
159 * Sanitizer::escapeId() was deprecated, use escapeIdForAttribute(),
160 escapeIdForLink() or escapeIdForExternalInterwiki() instead.
161 * Title::escapeFragmentForURL() was deprecated, use one of the aforementioned
162 Sanitizer functions or, if possible, Title::getFragmentForURL().
163 * Second parameter to Sanitizer::escapeIdReferenceList() ($options) now does
164 nothing and is deprecated.
165 * mw.util.escapeId() was deprecated, use escapeIdForAttribute() or
166 escapeIdForLink().
167 * MagicWord::replaceMultiple() (deprecated in 1.25) was removed.
168 * WikiImporter now requires the second parameter to be an instance of the Config,
169 class. Prior to that, the Config parameter was optional (a behavior deprecated in
170 1.25).
171 * Removed 'jquery.mwExtension' module. (deprecated since 1.26)
172 * mediawiki.ui: Deprecate greys, which are not part of WikimediaUI color palette
173 any more.

175 The namespaced classes in the Cdb namespace should be used instead.
176 * IPSet class (deprecated in 1.26) was removed. The namespaced IPSet\IPSet
177 should be used instead.
178 * RunningStat class (deprecated in 1.27) was removed. The namespaced
179 RunningStat\RunningStat should be used instead.
180 * MWMemcached and MemCachedClientforWiki classes (deprecated in 1.27) were removed.
181 The MemcachedClient class should be used instead.
182
183 == Compatibility ==
184 MediaWiki 1.30 requires PHP 5.5.9 or later. There is experimental support for
185 HHVM 3.6.5 or later.
186
187 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
188 but support for them is somewhat less mature. There is experimental support for
189 Oracle and Microsoft SQL Server.
190
191 The supported versions are:
192
193 * MySQL 5.5.8 or later
194 * PostgreSQL 8.3 or later
195 * SQLite 3.3.7 or later
196 * Oracle 9.0.1 or later
197 * Microsoft SQL Server 2005 (9.00.1399)
198
199 == Upgrading ==
200 1.30 has several database changes since 1.29, and will not work without schema
201 updates. Note that due to changes to some very large tables like the revision
202 table, the schema update may take a long time (minutes on a medium sized site,
203 many hours on a large site).
204
205 Don't forget to always back up your database before upgrading!
206
207 See the file UPGRADE for more detailed upgrade instructions, including
208 important information when upgrading from versions prior to 1.11.
