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
  37 === New features in 1.29 ===
  38 * (T5233) A cookie can now be set when a user is autoblocked, to track that user
  39   if they move to a new IP address. This is disabled by default.
  40 * Added ILocalizedException interface to standardize the use of localized
  41   exceptions, largely so the API can handle them more sensibly.
  42 * Blocks created automatically by MediaWiki, such as for configured proxies or
  43   dnsbls, are now indicated as such and use a new i18n message when displayed.
  44 * Added new $wgHTTPImportTimeout setting. Sets timeout for
  45   downloading the XML dump during a transwiki import in seconds.
  46 * Parser limit report is now available in machine-readable format to JavaScript
  47   via mw.config.get('wgPageParseReport').
  48 * Added $wgSoftBlockRanges, to allow for automatically blocking anonymous edits
  49   from certain IP ranges (e.g. private IPs).
  50 * (T59603) Added new magic word {{PAGELANGUAGE}} which returns the language code
  51   of the page being parsed.
  52 * HTML5 form validation attributes will no longer be suppressed. Originally
  53   browsers had poor support for them, but modern browsers handle them fine.
  54   This might affect some forms that used them and only worked because the
  55   attributes were not actually being set.
  56 * Expiry times can now be specified when users are added to user groups.
  57
  58 === External library changes in 1.29 ===
  59
  60 ==== Upgraded external libraries ====
  61 * Updated QUnit from v1.22.0 to v1.23.1.
  62 * Updated cssjanus from v1.1.2 to 1.1.3.
  63 * Updated psr/log from v1.0.0 to v1.0.2.
  64 * Update Moment.js from v2.8.4 to v2.15.0.
  65
  66 ==== New external libraries ====
  67
  68 ==== Removed and replaced external libraries ====
  69
  70 === Bug fixes in 1.29 ===
  71 * (T62604) Core parser functions returning a number now format the number according
  72   to the page content language, not wiki content language.
  73 * (T27187) Search suggestions based on jquery.suggestions will now correctly only
  74   highlight prefix matches in the results.
  75 * (T157035) "new mw.Uri()" was ignoring options when using default URI.
  76
  77 === Action API changes in 1.29 ===
  78 * Submitting sensitive authentication request parameters to action=login,
  79   action=clientlogin, action=createaccount, action=linkaccount, and
  80   action=changeauthenticationdata in the query string is now an error. They
  81   should be submitted in the POST body instead.
  82 * The capture option for action=resetpassword has been removed
  83 * action=clearhasmsg now requires a POST.
  84 * (T47843) API errors and warnings may be requested in non-English languages
  85   using the new 'errorformat', 'errorlang', and 'errorsuselocal' parameters.
  86 * API error codes may have changed. Most notably, errors from modules using
  87   parameter prefixes (e.g. all query submodules) will no longer be prefixed.
  88 * ApiPageSet-using modules will report the 'invalidreason' using the specified
  89   'errorformat'.
  90 * action=emailuser may return a "Warnings" status, and now returns 'warnings' and
  91   'errors' subelements (as applicable) instead of 'message'.
  92 * action=imagerotate returns an 'errors' subelement rather than 'errormessage'.
  93 * action=move now reports errors when moving the talk page as an array under
  94   key 'talkmove-errors', rather than using 'talkmove-error-code' and
  95   'talkmove-error-info'. The format for subpage move errors has also changed.
  96 * action=revisiondelete no longer includes a "rendered" property on warnings
  97   and errors for each item. Use errorformat=wikitext if you're wanting parsed
  98   output.
  99 * action=rollback no longer returns a "messageHtml" property. Use
 100   errorformat=html if you're wanting HTML formatting of error messages.
 101 * action=upload now reports optional stash failures as an array under key
 102   'stasherrors' rather than a 'stashfailed' text string.
 103 * action=watch reports 'errors' and 'warnings' instead of a single 'error', and
 104   no longer returns a 'message' on success.
 105 * Added action=validatepassword to validate passwords for the account creation
 106   and password change forms.
 107 * action=purge now requires a POST.
 108
 109 === Action API internal changes in 1.29 ===
 110 * New methods were added to ApiBase to handle errors and warnings using i18n
 111   keys. Methods for using hard-coded English messages were deprecated:
 112   * ApiBase::dieUsage() was deprecated
 113   * ApiBase::dieUsageMsg() was deprecated
 114   * ApiBase::dieUsageMsgOrDebug() was deprecated
 115   * ApiBase::getErrorFromStatus() was deprecated
 116   * ApiBase::parseMsg() was deprecated
 117   * ApiBase::setWarning() was deprecated
 118 * ApiBase::$messageMap is no longer public. Code attempting to access it will
 119   result in a PHP fatal error.
 120 * The $message parameter to the ApiCheckCanExecute hook should be set to an
 121   ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
 122   code for ApiBase::parseMsg() will no longer work.
 123 * UsageException is deprecated in favor of ApiUsageException. For the time
 124   being ApiUsageException is a subclass of UsageException to allow things that
 125   catch only UsageException to still function properly.
 126 * If, for some strange reason, code was using an ApiErrorFormatter instead of
 127   ApiErrorFormatter_BackCompat, note that the result format has changed and
 128   various methods now take a module path rather than a module name.
 129 * ApiMessageTrait::getApiCode() now strips 'apierror-' and 'apiwarn-' prefixes
 130   from the message key, and maps some message keys for backwards compatibility.
 131
 132 === Languages updated in 1.29 ===
 133
 134 MediaWiki supports over 350 languages. Many localisations are updated
 135 regularly. Below only new and removed languages are listed, as well as
 136 changes to languages because of Phabricator reports.
 137
 138 * Based as always on linguistic studies on intelligibility and language
 139   knowledge by geography, language fallbacks have been expanded. When a
 140   translation is missing in the user's preferred interface language, the
 141   corresponding translation for the fallback language will be used instead.
 142   English will only be used as last resort when there are no translations.
 143   Some configurations (such as date formats and gender namespaces) have also
 144   been updated when using the fallback language's configuration was inadequate.
 145   The new or reinstated language fallbacks are (after cs ↔ sk in 1.28):
 146   ca ↔ oc; hsb ↔ dsb; io → eo; mdf → ru; pnt → el; roa-tara → it; rup → ro;
 147   sh → bs, sr-el, hr.
 148 * (T155957) Talk Namespaces for Javanese language (jv) have been updated.
 149
 150 ==== No fallback for Ukrainian ====
 151 * (T39314) The fallback from Ukrainian to Russian was removed. The Ukrainian
 152   language will now use the default fallback language: English. When a translation
 153   to Ukrainian is not available, an English string will be shown.
 154
 155 === Other changes in 1.29 ===
 156 * Database::getSearchEngine() (deprecated in 1.28) was removed. Use
 157   SearchEngineFactory::getSearchEngineClass() instead.
 158 * $wgSessionsInMemcached (deprecated in 1.20) was removed. No replacement is
 159   required as all sessions are stored in Object Cache now.

 161   Status return type is deprecated.

 194 * wiki.phtml entry point was removed.  Refer to index.php instead. If you want "wiki.phtml"
 195   URLs to continue to work, set up redirects. In Apache, this can be done by enabling
 196   mod_rewrite and adding the following rules to your configuration:
 197
 198     RewriteEngine On

 237   UsersPager::buildGroupLink() was changed from a static to an instance method.

 244
 245 == Compatibility ==
 246
 247 MediaWiki 1.29 requires PHP 5.5.9 or later. There is experimental support for
 248 HHVM 3.6.5 or later.
 249
 250 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 251 support for them is somewhat less mature. There is experimental support for
 252 Oracle and Microsoft SQL Server.
 253
 254 The supported versions are:
 255
 256 * MySQL 5.0.3 or later
 257 * PostgreSQL 8.3 or later
 258 * SQLite 3.3.7 or later
 259 * Oracle 9.0.1 or later
 260 * Microsoft SQL Server 2005 (9.00.1399)
 261
 262 == Upgrading ==
 263
 264 1.29 has several database changes since 1.28, and will not work without schema
 265 updates. Note that due to changes to some very large tables like the revision
 266 table, the schema update may take quite long (minutes on a medium sized site,
 267 many hours on a large site).
 268
 269 If upgrading from before 1.11, and you are using a wiki as a commons
 270 repository, make sure that it is updated as well. Otherwise, errors may arise
 271 due to database schema changes.
 272
 273 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 274 new database fields are filled with data.
 275
 276 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 277 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 278 with MediaWiki 1.21.
 279
 280 Don't forget to always back up your database before upgrading!
 281
 282 See the file UPGRADE for more detailed upgrade instructions.
 283
 284 For notes on 1.28.x and older releases, see HISTORY.
 285
