RELEASE-NOTES-1.29

   1 == MediaWiki 1.29 ==
   2
   3 THIS IS NOT A RELEASE YET
   4
   5 MediaWiki 1.29 is an alpha-quality branch and is not recommended for use in
   6 production.
   7
   8 === Configuration changes in 1.29 ===
   9 * Default cookie expiration time has been reduced to 30 days. Login cookie
  10   expiration time is kept at 180 days.
  11 * A new configuration variable has been added: $wgCookieSetOnAutoblock. This
  12   determines whether to set a cookie when a user is autoblocked. Doing so means
  13   that a blocked user, even after logging out and moving to a new IP address,
  14   will still be blocked.
  15 * The resetpassword right and associated password reset capture feature has
  16   been removed.
  17 * The $error parameter to the EmailUser hook should be set to a Status object
  18   or boolean false. This should be compatible with at least MediaWiki 1.23 if
  19   not earlier. Returning a raw HTML string is now deprecated.
  20 * The $message parameter to the ApiCheckCanExecute hook should be set to an
  21   ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
  22   code for ApiBase::parseMsg() will no longer work.
  23 * ApiBase::$messageMap is no longer public. Code attempting to access it will
  24   result in a PHP fatal error.
  25 * $wgUserEmailUseReplyTo is now true by default to work around restrictive DMARC
  26   policies.
  27 * Subpages are now enabled by default in the Template namespace. Set
  28   $wgNamespacesWithSubpages[NS_TEMPLATE] to false to keep the old behavior.
  29 * $wgRunJobsAsync is now false by default (T142751). This change only affects
  30   wikis with $wgJobRunRate > 0.
  31 * A temporary feature flag, $wgDisableUserGroupExpiry, is provided to disable
  32   new features that rely on the schema changes to the user_groups table. This
  33   feature flag will likely be removed before 1.29 is released.
  34 * (T158474) "Unknown user" has been added to $wgReservedUsernames.
  35 * (T156983) $wgRateLimitsExcludedIPs now accepts CIDR ranges as well as single IPs.
  36 * $wgDummyLanguageCodes is deprecated. Additional language code mappings may be
  37   added to $wgExtraLanguageCodes instead.
  38
  39 === New features in 1.29 ===
  40 * (T137376) New language support: Atikamekw (atj)
  41 * (T5233) A cookie can now be set when a user is autoblocked, to track that user
  42   if they move to a new IP address. This is disabled by default.
  43 * Added ILocalizedException interface to standardize the use of localized
  44   exceptions, largely so the API can handle them more sensibly.
  45 * Blocks created automatically by MediaWiki, such as for configured proxies or
  46   dnsbls, are now indicated as such and use a new i18n message when displayed.
  47 * Added new $wgHTTPImportTimeout setting. Sets timeout for
  48   downloading the XML dump during a transwiki import in seconds.
  49 * Parser limit report is now available in machine-readable format to JavaScript
  50   via mw.config.get('wgPageParseReport').
  51 * Added $wgSoftBlockRanges, to allow for automatically blocking anonymous edits
  52   from certain IP ranges (e.g. private IPs).
  53 * (T59603) Added new magic word {{PAGELANGUAGE}} which returns the language code
  54   of the page being parsed.
  55 * HTML5 form validation attributes will no longer be suppressed. Originally
  56   browsers had poor support for them, but modern browsers handle them fine.
  57   This might affect some forms that used them and only worked because the
  58   attributes were not actually being set.
  59 * Expiry times can now be specified when users are added to user groups.
  60 * Completely new user interface for the RecentChanges page, which
  61   structures filters into user-friendly groups.  This has corresponding
  62   changes to how filters are registered by core and extensions.
  63
  64 === External library changes in 1.29 ===
  65
  66 ==== Upgraded external libraries ====
  67 * Added wikimedia/timestamp v1.0.0.
  68 * Updated QUnit from v1.22.0 to v1.23.1.
  69 * Updated cssjanus from v1.1.2 to 1.1.3.
  70 * Updated psr/log from v1.0.0 to v1.0.2.

  74
  75 ==== New external libraries ====
  76
  77 ==== Removed and replaced external libraries ====
  78
  79 === Bug fixes in 1.29 ===
  80 * (T62604) Core parser functions returning a number now format the number according
  81   to the page content language, not wiki content language.
  82 * (T27187) Search suggestions based on jquery.suggestions will now correctly only
  83   highlight prefix matches in the results.
  84 * (T157035) "new mw.Uri()" was ignoring options when using default URI.
  85 * Special:Allpages can no longer be filtered by redirect in miser mode.
  86
  87 === Action API changes in 1.29 ===
  88 * Submitting sensitive authentication request parameters to action=login,
  89   action=clientlogin, action=createaccount, action=linkaccount, and
  90   action=changeauthenticationdata in the query string is now an error. They
  91   should be submitted in the POST body instead.
  92 * The capture option for action=resetpassword has been removed
  93 * action=clearhasmsg now requires a POST.
  94 * (T47843) API errors and warnings may be requested in non-English languages
  95   using the new 'errorformat', 'errorlang', and 'errorsuselocal' parameters.
  96 * API error codes may have changed. Most notably, errors from modules using
  97   parameter prefixes (e.g. all query submodules) will no longer be prefixed.
  98 * ApiPageSet-using modules will report the 'invalidreason' using the specified
  99   'errorformat'.
 100 * action=emailuser may return a "Warnings" status, and now returns 'warnings' and
 101   'errors' subelements (as applicable) instead of 'message'.
 102 * action=imagerotate returns an 'errors' subelement rather than 'errormessage'.
 103 * action=move now reports errors when moving the talk page as an array under
 104   key 'talkmove-errors', rather than using 'talkmove-error-code' and
 105   'talkmove-error-info'. The format for subpage move errors has also changed.
 106 * action=revisiondelete no longer includes a "rendered" property on warnings
 107   and errors for each item. Use errorformat=wikitext if you're wanting parsed
 108   output.
 109 * action=rollback no longer returns a "messageHtml" property. Use
 110   errorformat=html if you're wanting HTML formatting of error messages.
 111 * action=upload now reports optional stash failures as an array under key
 112   'stasherrors' rather than a 'stashfailed' text string.
 113 * action=watch reports 'errors' and 'warnings' instead of a single 'error', and
 114   no longer returns a 'message' on success.
 115 * Added action=validatepassword to validate passwords for the account creation
 116   and password change forms.
 117 * action=purge now requires a POST.
 118 * There is a new `languagevariants` siprop for action=query&meta=siteinfo,
 119   which returns a list of languages with active LanguageConverter instances.
 120 * action=query&query=allpages will no longer filter redirects using a database
 121   query in miser mode. This may result in less results being returned than were
 122   requested.
 123
 124 === Action API internal changes in 1.29 ===
 125 * New methods were added to ApiBase to handle errors and warnings using i18n
 126   keys. Methods for using hard-coded English messages were deprecated:
 127   * ApiBase::dieUsage() was deprecated
 128   * ApiBase::dieUsageMsg() was deprecated
 129   * ApiBase::dieUsageMsgOrDebug() was deprecated
 130   * ApiBase::getErrorFromStatus() was deprecated
 131   * ApiBase::parseMsg() was deprecated
 132   * ApiBase::setWarning() was deprecated
 133 * ApiBase::$messageMap is no longer public. Code attempting to access it will
 134   result in a PHP fatal error.
 135 * The $message parameter to the ApiCheckCanExecute hook should be set to an
 136   ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
 137   code for ApiBase::parseMsg() will no longer work.
 138 * UsageException is deprecated in favor of ApiUsageException. For the time
 139   being ApiUsageException is a subclass of UsageException to allow things that
 140   catch only UsageException to still function properly.
 141 * If, for some strange reason, code was using an ApiErrorFormatter instead of
 142   ApiErrorFormatter_BackCompat, note that the result format has changed and
 143   various methods now take a module path rather than a module name.
 144 * ApiMessageTrait::getApiCode() now strips 'apierror-' and 'apiwarn-' prefixes
 145   from the message key, and maps some message keys for backwards compatibility.
 146
 147 === Languages updated in 1.29 ===
 148
 149 MediaWiki supports over 350 languages. Many localisations are updated
 150 regularly. Below only new and removed languages are listed, as well as
 151 changes to languages because of Phabricator reports.
 152
 153 * Based as always on linguistic studies on intelligibility and language
 154   knowledge by geography, language fallbacks have been expanded. When a
 155   translation is missing in the user's preferred interface language, the
 156   corresponding translation for the fallback language will be used instead.
 157   English will only be used as last resort when there are no translations.
 158   Some configurations (such as date formats and gender namespaces) have also
 159   been updated when using the fallback language's configuration was inadequate.
 160   The new or reinstated language fallbacks are (after cs ↔ sk in 1.28):
 161   ca ↔ oc; hsb ↔ dsb; io → eo; mdf → ru; pnt → el; roa-tara → it; rup → ro;
 162   sh → bs, sr-el, hr.
 163 * (T155957) Talk Namespaces for Javanese language (jv) have been updated.
 164
 165 ==== No fallback for Ukrainian ====
 166 * (T39314) The fallback from Ukrainian to Russian was removed. The Ukrainian
 167   language will now use the default fallback language: English. When a translation
 168   to Ukrainian is not available, an English string will be shown.
 169
 170 === Other changes in 1.29 ===
 171 * Database::getSearchEngine() (deprecated in 1.28) was removed. Use
 172   SearchEngineFactory::getSearchEngineClass() instead.
 173 * $wgSessionsInMemcached (deprecated in 1.20) was removed. No replacement is
 174   required as all sessions are stored in Object Cache now.
 175 * MWHttpRequest::execute() should be considered to return a StatusValue; the
 176   Status return type is deprecated.

 208   and outdated lists of errors/warnings returned by the API, are now deprecated.
 209 * wiki.phtml entry point was removed.  Refer to index.php instead. If you want "wiki.phtml"
 210   URLs to continue to work, set up redirects. In Apache, this can be done by enabling
 211   mod_rewrite and adding the following rules to your configuration:
 212
 213     RewriteEngine On
 214     RewriteBase /
 215     RewriteRule ^/w/wiki\.phtml$ /w/index.php [R=301,L]

 239 * refreshLinks.php now can be limited to a particular category with --category=...
 240   or a tracking category with --tracking-category=...
 241 * User-like objects that are passed to SpecialUserRights and its subclasses are
 242   now required to have a getGroupMemberships() method. See UserRightsProxy for
 243   an example.
 244 * User::$mGroups (instance variable) was marked private. Use User::getGroups()
 245   instead.
 246 * User::getGroupName(), User::getGroupMember(), User:getGroupPage(),
 247   User::makeGroupLinkHTML(), and User::makeGroupLinkWiki() were deprecated.
 248   Use equivalent methods on the UserGroupMembership class.
 249 * Maintenance scripts and tests that call User::addGroup() must now ensure that
 250   User objects have been added to the database prior to calling addGroup().
 251 * Protected function UsersPager::getGroups() was removed, and protected function
 252   UsersPager::buildGroupLink() was changed from a static to an instance method.
 253 * The third parameter ($cache) to the UsersPagerDoBatchLookups hook was changed;
 254   see docs/hooks.txt.
 255 * User::crypt() (deprecated in 1.24) was removed.
 256 * User::comparePasswords() (deprecated in 1.24) was removed.
 257 * ArchivedFile::getUserText() (deprecated in 1.23) was removed.
 258 * HTMLFileCache::newFromTitle() (deprecated in 1.24) was removed.
 259 * BREAKING CHANGE: Internal signature changes to ChangesListSpecialPage
 260   and subclasses.  It should only break if you call buildMainQueryConds
 261   (changed to buildQuery with new signature) or doMainQuery (new
 262   signature).  Subclasses are likely to call at least doMainQuery
 263   (possibly both), but other classes might too, because they were
 264   public.
 265   Also, some related hooks were deprecated, but this is not yet a
 266   breaking change.
 267 * Removed 'jquery.arrowSteps' module. (deprecated since 1.28)
 268 * The 'jquery.autoEllipsis' ResourceLoader module is now deprecated.
 269 * WikiRevision::$fileIsTemp was deprecated.
 270 * WikiRevision::$importer was deprecated.
 271 * WikiRevision::$user was deprecated.
 272
 273 == Compatibility ==
 274
 275 MediaWiki 1.29 requires PHP 5.5.9 or later. There is experimental support for
 276 HHVM 3.6.5 or later.
 277
 278 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 279 support for them is somewhat less mature. There is experimental support for
 280 Oracle and Microsoft SQL Server.
 281
 282 The supported versions are:
 283
 284 * MySQL 5.0.3 or later
 285 * PostgreSQL 8.3 or later
 286 * SQLite 3.3.7 or later
 287 * Oracle 9.0.1 or later
 288 * Microsoft SQL Server 2005 (9.00.1399)
 289
 290 == Upgrading ==
 291
 292 1.29 has several database changes since 1.28, and will not work without schema
 293 updates. Note that due to changes to some very large tables like the revision
 294 table, the schema update may take quite long (minutes on a medium sized site,
 295 many hours on a large site).
 296
 297 If upgrading from before 1.11, and you are using a wiki as a commons
 298 repository, make sure that it is updated as well. Otherwise, errors may arise
 299 due to database schema changes.
 300
 301 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 302 new database fields are filled with data.
 303
 304 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 305 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 306 with MediaWiki 1.21.
 307
 308 Don't forget to always back up your database before upgrading!
 309
 310 See the file UPGRADE for more detailed upgrade instructions.
 311
 312 For notes on 1.28.x and older releases, see HISTORY.
