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
  50 === Action API changes in 1.29 ===
  51 * Submitting sensitive authentication request parameters to action=clientlogin,
  52   action=createaccount, action=linkaccount, and action=changeauthenticationdata
  53   in the query string is now an error. They should be submitted in the POST
  54   body instead.
  55 * The capture option for action=resetpassword has been removed
  56 * action=clearhasmsg now requires a POST.
  57 * (T47843) API errors and warnings may be requested in non-English languages
  58   using the new 'errorformat', 'errorlang', and 'errorsuselocal' parameters.
  59 * API error codes may have changed. Most notably, errors from modules using
  60   parameter prefixes (e.g. all query submodules) will no longer be prefixed.
  61 * ApiPageSet-using modules will report the 'invalidreason' using the specified
  62   'errorformat'.
  63 * action=emailuser may return a "Warnings" status, and now returns 'warnings' and
  64   'errors' subelements (as applicable) instead of 'message'.
  65 * action=imagerotate returns an 'errors' subelement rather than 'errormessage'.
  66 * action=move now reports errors when moving the talk page as an array under
  67   key 'talkmove-errors', rather than using 'talkmove-error-code' and
  68   'talkmove-error-info'. The format for subpage move errors has also changed.
  69 * action=revisiondelete no longer includes a "rendered" property on warnings
  70   and errors for each item. Use errorformat=wikitext if you're wanting parsed
  71   output.
  72 * action=rollback no longer returns a "messageHtml" property. Use
  73   errorformat=html if you're wanting HTML formatting of error messages.
  74 * action=upload now reports optional stash failures as an array under key
  75   'stasherrors' rather than a 'stashfailed' text string.
  76 * action=watch reports 'errors' and 'warnings' instead of a single 'error', and
  77   no longer returns a 'message' on success.
  78 * Added action=validatepassword to validate passwords for the account creation
  79   and password change forms.
  80
  81 === Action API internal changes in 1.29 ===
  82 * New methods were added to ApiBase to handle errors and warnings using i18n
  83   keys. Methods for using hard-coded English messages were deprecated:
  84   * ApiBase::dieUsage() was deprecated
  85   * ApiBase::dieUsageMsg() was deprecated
  86   * ApiBase::dieUsageMsgOrDebug() was deprecated
  87   * ApiBase::getErrorFromStatus() was deprecated
  88   * ApiBase::parseMsg() was deprecated
  89   * ApiBase::setWarning() was deprecated
  90 * ApiBase::$messageMap is no longer public. Code attempting to access it will
  91   result in a PHP fatal error.
  92 * The $message parameter to the ApiCheckCanExecute hook should be set to an
  93   ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
  94   code for ApiBase::parseMsg() will no longer work.
  95 * UsageException is deprecated in favor of ApiUsageException. For the time
  96   being ApiUsageException is a subclass of UsageException to allow things that
  97   catch only UsageException to still function properly.
  98 * If, for some strange reason, code was using an ApiErrorFormatter instead of
  99   ApiErrorFormatter_BackCompat, note that the result format has changed and
 100   various methods now take a module path rather than a module name.
 101 * ApiMessageTrait::getApiCode() now strips 'apierror-' and 'apiwarn-' prefixes
 102   from the message key, and maps some message keys for backwards compatibility.
 103
 104 === Languages updated in 1.29 ===
 105
 106 MediaWiki supports over 350 languages. Many localisations are updated
 107 regularly. Below only new and removed languages are listed, as well as
 108 changes to languages because of Phabricator reports.
 109
 110 ==== No fallback for Ukrainian ====
 111 * (T39314) The fallback from Ukrainian to Russian was removed. The Ukrainian
 112   language will now use the default fallback language: English. When a translation
 113   to Ukrainian is not available, an English string will be shown.
 114
 115 === Other changes in 1.29 ===
 116 * Database::getSearchEngine() (deprecated in 1.28) was removed. Use
 117   SearchEngineFactory::getSearchEngineClass() instead.
 118 * $wgSessionsInMemcached (deprecated in 1.20) was removed. No replacement is
 119   required as all sessions are stored in Object Cache now.
 120 * MWHttpRequest::execute() should be considered to return a StatusValue; the
 121   Status return type is deprecated.
 122 * User::edits() (deprecated in 1.21) was removed.
 123 * Xml::escapeJsString() (deprecated in 1.21) was removed.
 124 * Article::getText() and Article::prepareTextForEdit() (deprecated in 1.21)
 125   were removed.
 126 * Article::getAutosummary() and WikiPage::getAutosummary (deprecated in 1.21)
 127   were removed.
 128 * Hooks ArticleViewCustom, EditPageGetDiffText and ShowRawCssJs (deprecated in 1.21)
 129   were removed.
 130 * Class RevisiondeleteAction (deprecated in 1.25) was removed.
 131 * WikiPage::prepareTextForEdit() (deprecated in 1.21) was removed.
 132 * WikiPage::getText() (deprecated in 1.21) was removed.
 133 * Article::fetchContent() (deprecated in 1.21) was removed.
 134 * User::getPassword() (deprecated in 1.27) was removed.
 135 * User::getTemporaryPassword() (deprecated in 1.27) was removed.
 136 * User::isPasswordReminderThrottled() (deprecated in 1.27) was removed.
 137
 138 == Compatibility ==
 139
 140 MediaWiki 1.29 requires PHP 5.5.9 or later. There is experimental support for
 141 HHVM 3.6.5 or later.
 142
 143 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 144 support for them is somewhat less mature. There is experimental support for
 145 Oracle and Microsoft SQL Server.
 146
 147 The supported versions are:
 148
 149 * MySQL 5.0.3 or later
 150 * PostgreSQL 8.3 or later
 151 * SQLite 3.3.7 or later
 152 * Oracle 9.0.1 or later
 153 * Microsoft SQL Server 2005 (9.00.1399)
 154
 155 == Upgrading ==
 156
 157 1.29 has several database changes since 1.28, and will not work without schema
 158 updates. Note that due to changes to some very large tables like the revision
 159 table, the schema update may take quite long (minutes on a medium sized site,
 160 many hours on a large site).
 161
 162 If upgrading from before 1.11, and you are using a wiki as a commons
 163 repository, make sure that it is updated as well. Otherwise, errors may arise
 164 due to database schema changes.
 165
 166 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 167 new database fields are filled with data.
 168
 169 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 170 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 171 with MediaWiki 1.21.
 172
 173 Don't forget to always back up your database before upgrading!
 174
 175 See the file UPGRADE for more detailed upgrade instructions.
