5 THIS IS NOT A RELEASE YET

7 MediaWiki 1.34 is an alpha-quality development branch, and is not recommended
8 for use in production.
9
10 == Upgrading notes for 1.34 ==
11 1.34 has several database changes since 1.33, and will not work without schema
12 updates. Note that due to changes to some very large tables like the revision
13 table, the schema update may take quite long (minutes on a medium sized site,
14 many hours on a large site).
15
16 Don't forget to always back up your database before upgrading!
17
18 See the file UPGRADE for more detailed upgrade instructions, including
19 important information when upgrading from versions prior to 1.11.

57 === Bug fixes in 1.34 ===
58 * (T222529) If a log entry or page revision is recorded in the database with an
59 empty username, attempting to display it will log an error and return a "no
60 username available" to the user instead of silently displaying nothing or
61 invalid links.
62
63 === Action API changes in 1.34 ===
64 * The 'recenteditcount' response property from action=query list=allusers,
65 deprecated in 1.25, has been removed.
66

68 * …
69
70 === Languages updated in 1.34 ===
71 MediaWiki supports over 350 languages. Many localisations are updated regularly.
72 Below only new and removed languages are listed, as well as changes to languages
73 because of Phabricator reports.
74
75 * (T152908) Added language support for N'Ko (nqo).
76
77 === Breaking changes in 1.34 ===
78 * Preferences class, deprecated in 1.31, has been removed.
79 * The following parts of code, deprecated in 1.32, were removed in favor of
80 built-in PHP functions:
81 * CryptRand class
82 * CryptRand service
83 * Functions of the MWCryptRand class: singleton(), wasStrong() and generate().
84 * Language::setCode, deprecated in 1.32, was removed. Use Language::factory to
85 create a new Language object with a different language code.
86 * MWNamespace::clearCaches() has been removed. So has the $rebuild parameter
87 to MWNamespace::getCanonicalNamespaces(), which was deprecated since 1.31.
88 Instead, reset services, such as by calling $this->overrideMwServices() (if
89 your test extends MediaWikiTestCase). Services will generally not pick up
90 configuration changes from after they were created, so you must reset
91 services after any configuration change. Even if your code works now, it is
92 likely to break in future versions as more code is moved to services.
93 * The ill-defined "DatabaseOraclePostInit" hook has been removed.
94 * PreferencesFormLegacy and PreferencesForm classes, deprecated in 1.32, have
95 been removed.
96 * ObjectFactory class, deprecated in 1.31, has been removed.
97 * HWLDFWordAccumudlator class, deprecated in 1.28, has been removed.
98 * XMPInfo, XMPReader and XMPValidate, deprecated in 1.32, have been removed.
99 * The RedirectSpecialPage::execute method could sometimes return a Title object.
100 This behavior was removed, and the method now matches the parent signature
101 (SpecialPage::execute) which is to return HTML string or void.
102 To obtain the destination title, use RedirectSpecialPage::getRedirect.
103 * The 'recenteditcount' response property from action API action=query
104 list=allusers, deprecated in 1.25, has been removed.
105 * SearchEngine::userNamespaces(), SearchEngine::namespacesAsText(),
106 SearchEngine::create(), SearchEngine::getSearchTypes() and
107 SearchEngine::getNearMatch(), methods deprecated in 1.27, have been removed.
108 * FileRepo::streamFile(), deprecated in 1.26, has been removed.
109 * User::randomPassword() method, deprecated in 1.27, have been removed.
110 * MWNamespace::canTalk(), deprecated in 1.30, have been removed.
111 * Parser class property $mUniqPrefix, deprecated in 1.26, has been removed.
112 * wfArrayFilter() and wfArrayFilterByKey(), deprecated in 1.32, have been
113 removed.
114 * wfMakeUrlIndexes() function, deprecated in 1.33, have been removed.
115 * User::getGroupPage() and ::makeGroupLinkHTML(), deprecated in 1.29, have been
116 removed. Use UserGroupMembership::getGroupPage and ::getLink instead.
117 * User::makeGroupLinkWiki(), deprecated in 1.29, has been removed. Use
118 UserGroupMembership::getLink() instead.
119 * …
120
121 === Deprecations in 1.34 ===
122 * The MWNamespace class is deprecated. Use NamespaceInfo.
123 * ExtensionRegistry->load() is deprecated, as it breaks dependency checking.
124 Instead, use ->queue().
125 * User::isBlocked() is deprecated since it does not tell you if the user is
126 blocked from editing a particular page. Use User::getBlock() or
127 PermissionManager::isBlockedFrom() or PermissionManager::userCan() instead.
128 * User::isLocallyBlockedProxy and User::inDnsBlacklist are deprecated and moved
129 to the BlockManager as private helper methods.
130 * User::isDnsBlacklisted is deprecated. Use BlockManager::isDnsBlacklisted
131 instead.
132 * The Config argument to ChangesListSpecialPage::checkStructuredFilterUiEnabled
133 is deprecated. Pass only the User argument.
134 * WatchedItem::getUser is deprecated. Use getUserIdentity.
135 * Passing a Title as the first parameter to the getTimestampById method of
136 RevisionStore is deprecated. Omit it, passing only the remaining parameters.
137 * Title::getPreviousRevisionId and Title::getNextRevisionId are deprecated. Use
138 RevisionLookup::getPreviousRevision and RevisionLookup::getNextRevision.
139 * The Title parameter to RevisionLookup::getPreviousRevision and
140 RevisionLookup::getNextRevision is deprecated and should be omitted.
141 * MWHttpRequest::factory is deprecated. Use HttpRequestFactory.
142 * The Http class is deprecated. For the request, get, and post methods, use
143 HttpRequestFactory. For isValidURI, use MWHttpRequest::isValidURI. For
144 getProxy, use (string)$wgHTTPProxy. For createMultiClient, construct a
145 MultiHttpClient directly.
146 * Http::$httpEngine is deprecated and has no replacement. The default 'guzzle'
147 engine will eventually be made the only engine for HTTP requests.
148 * RepoGroup::singleton(), RepoGroup::destroySingleton(),
149 RepoGroup::setSingleton(), wfFindFile(), and wfLocalFile() are all
150 deprecated. Use MediaWikiServices instead.
151 * The getSubjectPage, getTalkPage, and getOtherPage of Title are deprecated.
152 Use NamespaceInfo's getSubjectPage, getTalkPage, and getAssociatedPage.
153
154 === Other changes in 1.34 ===

157 == Compatibility ==
158 MediaWiki 1.34 requires PHP 7.0.13 or later. Although HHVM 3.18.5 or later is
159 supported, it is generally advised to use PHP 7.0.13 or later for long term
160 support.
161
162 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
163 but support for them is somewhat less mature. There is experimental support for
164 Oracle and Microsoft SQL Server.
165
166 The supported versions are:
167
168 * MySQL 5.5.8 or later
169 * PostgreSQL 9.2 or later
170 * SQLite 3.8.0 or later
171 * Oracle 9.0.1 or later
172 * Microsoft SQL Server 2005 (9.00.1399)
