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 expiration time is
  10   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 policies.
  26 * Subpages are now enabled by default in the Template namespace. Set
  27   $wgNamespacesWithSubpages[NS_TEMPLATE] to false to keep the old behavior.
  28 * $wgRunJobsAsync is now false by default (T142751). This change only affects
  29   wikis with $wgJobRunRate > 0.
  30
  31 === New features in 1.29 ===
  32 * (T5233) A cookie can now be set when a user is autoblocked, to track that user if
  33   they move to a new IP address. This is disabled by default.
  34 * Added ILocalizedException interface to standardize the use of localized
  35   exceptions, largely so the API can handle them more sensibly.
  36 * Blocks created automatically by MediaWiki, such as for configured proxies or
  37   dnsbls, are now indicated as such and use a new i18n message when displayed.
  38
  39 === External library changes in 1.29 ===
  40
  41 ==== Upgraded external libraries ====
  42 * Updated QUnit from v1.22.0 to v1.23.1.
  43
  44 ==== New external libraries ====
  45
  46 ==== Removed and replaced external libraries ====
  47
  48 === Bug fixes in 1.29 ===
  49 * (T62604) Core parser functions returning a number now format the number according
  50   to the page content language, not wiki content language.
  51
  52 === Action API changes in 1.29 ===
  53 * Submitting sensitive authentication request parameters to action=clientlogin,
  54   action=createaccount, action=linkaccount, and action=changeauthenticationdata
  55   in the query string is now an error. They should be submitted in the POST
  56   body instead.
  57 * The capture option for action=resetpassword has been removed
  58 * action=clearhasmsg now requires a POST.
  59 * (T47843) API errors and warnings may be requested in non-English languages
  60   using the new 'errorformat', 'errorlang', and 'errorsuselocal' parameters.
  61 * API error codes may have changed. Most notably, errors from modules using
  62   parameter prefixes (e.g. all query submodules) will no longer be prefixed.
  63 * ApiPageSet-using modules will report the 'invalidreason' using the specified
  64   'errorformat'.
  65 * action=emailuser may return a "Warnings" status, and now returns 'warnings' and
  66   'errors' subelements (as applicable) instead of 'message'.
  67 * action=imagerotate returns an 'errors' subelement rather than 'errormessage'.
  68 * action=move now reports errors when moving the talk page as an array under
  69   key 'talkmove-errors', rather than using 'talkmove-error-code' and
  70   'talkmove-error-info'. The format for subpage move errors has also changed.
  71 * action=revisiondelete no longer includes a "rendered" property on warnings
  72   and errors for each item. Use errorformat=wikitext if you're wanting parsed
  73   output.
  74 * action=rollback no longer returns a "messageHtml" property. Use
  75   errorformat=html if you're wanting HTML formatting of error messages.
  76 * action=upload now reports optional stash failures as an array under key
  77   'stasherrors' rather than a 'stashfailed' text string.
  78 * action=watch reports 'errors' and 'warnings' instead of a single 'error', and
  79   no longer returns a 'message' on success.
  80 * Added action=validatepassword to validate passwords for the account creation
  81   and password change forms.
  82
  83 === Action API internal changes in 1.29 ===
  84 * New methods were added to ApiBase to handle errors and warnings using i18n
  85   keys. Methods for using hard-coded English messages were deprecated:
  86   * ApiBase::dieUsage() was deprecated
  87   * ApiBase::dieUsageMsg() was deprecated
  88   * ApiBase::dieUsageMsgOrDebug() was deprecated
  89   * ApiBase::getErrorFromStatus() was deprecated
  90   * ApiBase::parseMsg() was deprecated
  91   * ApiBase::setWarning() was deprecated
  92 * ApiBase::$messageMap is no longer public. Code attempting to access it will
  93   result in a PHP fatal error.
  94 * The $message parameter to the ApiCheckCanExecute hook should be set to an
  95   ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
  96   code for ApiBase::parseMsg() will no longer work.
  97 * UsageException is deprecated in favor of ApiUsageException. For the time
  98   being ApiUsageException is a subclass of UsageException to allow things that
  99   catch only UsageException to still function properly.
 100 * If, for some strange reason, code was using an ApiErrorFormatter instead of
 101   ApiErrorFormatter_BackCompat, note that the result format has changed and
 102   various methods now take a module path rather than a module name.
 103 * ApiMessageTrait::getApiCode() now strips 'apierror-' and 'apiwarn-' prefixes
 104   from the message key, and maps some message keys for backwards compatibility.
 105
 106 === Languages updated in 1.29 ===
 107
 108 MediaWiki supports over 350 languages. Many localisations are updated
 109 regularly. Below only new and removed languages are listed, as well as
 110 changes to languages because of Phabricator reports.
 111
 112 * Based as always on linguistic studies on intelligibility and language
 113   knowledge by geography, language fallbacks have been expanded. When a
 114   translation is missing in the user's preferred interface language, the
 115   corresponding translation for the fallback language will be used instead.
 116   English will only be used as last resort when there are no translations.
 117   Some configurations (such as date formats and gender namespaces) have also
 118   been updated when using the fallback language's configuration was inadequate.
 119   The new or reinstated language fallbacks are (after cs ↔ sk in 1.28):
 120   hsb ↔ dsb, io → eo, mdf → ru, pnt → el, roa-tara → it.
 121
 122 ==== No fallback for Ukrainian ====
 123 * (T39314) The fallback from Ukrainian to Russian was removed. The Ukrainian
 124   language will now use the default fallback language: English. When a translation
 125   to Ukrainian is not available, an English string will be shown.
 126
 127 === Other changes in 1.29 ===
 128 * Database::getSearchEngine() (deprecated in 1.28) was removed. Use
 129   SearchEngineFactory::getSearchEngineClass() instead.
 130 * $wgSessionsInMemcached (deprecated in 1.20) was removed. No replacement is
 131   required as all sessions are stored in Object Cache now.
 132 * MWHttpRequest::execute() should be considered to return a StatusValue; the
 133   Status return type is deprecated.
 134 * User::edits() (deprecated in 1.21) was removed.
 135 * Xml::escapeJsString() (deprecated in 1.21) was removed.
 136 * Article::getText() and Article::prepareTextForEdit() (deprecated in 1.21)
 137   were removed.
 138 * Article::getAutosummary() and WikiPage::getAutosummary (deprecated in 1.21)
 139   were removed.
 140 * Hooks ArticleViewCustom, EditPageGetDiffText and ShowRawCssJs (deprecated in 1.21)
 141   were removed.
 142 * Class RevisiondeleteAction (deprecated in 1.25) was removed.
 143 * WikiPage::prepareTextForEdit() (deprecated in 1.21) was removed.
 144 * WikiPage::getText() (deprecated in 1.21) was removed.
 145 * Article::fetchContent() (deprecated in 1.21) was removed.
 146 * User::getPassword() (deprecated in 1.27) was removed.
 147 * User::getTemporaryPassword() (deprecated in 1.27) was removed.
 148 * User::isPasswordReminderThrottled() (deprecated in 1.27) was removed.
 149 * FSRepo (deprecated in 1.19) was removed.
 150
 151 == Compatibility ==
 152
 153 MediaWiki 1.29 requires PHP 5.5.9 or later. There is experimental support for
 154 HHVM 3.6.5 or later.
 155
 156 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 157 support for them is somewhat less mature. There is experimental support for
 158 Oracle and Microsoft SQL Server.
 159
 160 The supported versions are:
 161
 162 * MySQL 5.0.3 or later
 163 * PostgreSQL 8.3 or later
 164 * SQLite 3.3.7 or later
 165 * Oracle 9.0.1 or later
 166 * Microsoft SQL Server 2005 (9.00.1399)
 167
 168 == Upgrading ==
 169
 170 1.29 has several database changes since 1.28, and will not work without schema
 171 updates. Note that due to changes to some very large tables like the revision
 172 table, the schema update may take quite long (minutes on a medium sized site,
 173 many hours on a large site).
 174
 175 If upgrading from before 1.11, and you are using a wiki as a commons
 176 repository, make sure that it is updated as well. Otherwise, errors may arise
 177 due to database schema changes.
 178
 179 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 180 new database fields are filled with data.
 181
 182 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 183 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 184 with MediaWiki 1.21.
 185
 186 Don't forget to always back up your database before upgrading!
 187
 188 See the file UPGRADE for more detailed upgrade instructions.
