Change notes from older releases. For current info see RELEASE-NOTES-1.31.
= MediaWiki 1.30 =
== MediaWiki 1.30.0 ==
=== Changes since MediaWiki 1.30.0-rc.0 ===
* Upgraded Moment.js from v2.15.0 to v2.19.3.
* Add ip_changes to postgres/tables.sql.
* Skip null shell parameters.
* Add wfWaitForSlaves() to maintenance/migrateComments.php.
* (T182245) Fix join conditions in ImageListPager.
* (T178626) Revert #contentSub and #jump-to-nav margin changes.
=== MySQL version requirement in 1.30 ===
As of 1.30, MediaWiki now requires MySQL 5.5.8 or higher (see Compatibility
section).
=== Configuration changes in 1.30 ===
* The "C.UTF-8" locale should be used for $wgShellLocale, if available, to avoid
unexpected behavior when code uses locale-sensitive string comparisons. For
example, the Scribunto extension considers "bar" < "Foo" in most locales
since it ignores case.
* $wgShellLocale now affects LC_ALL rather than only LC_CTYPE. See
documentation of $wgShellLocale for details.
* $wgShellLocale is now applied for all requests. wfInitShellLocale() is
deprecated and a no-op, as it is no longer needed.
* $wgJobClasses may now specify callback functions as an alternative to plain
class names. This is intended for extensions that want control over the
instantiation of their jobs, to allow for proper dependency injection.
* $wgResourceModules may now specify callback functions as an alternative
to plain class names, using the 'factory' key in the module description
array. This allows dependency injection to be used for ResourceLoader modules.
* $wgExceptionHooks has been removed.
* (T163562) $wgRangeContributionsCIDRLimit was introduced to control the size
of IP ranges that can be queried at Special:Contributions.
* (T45547) $wgUsePigLatinVariant added (off by default).
* (T152540) MediaWiki now supports a section ID escaping style that allows to display
non-Latin characters verbatim on many modern browsers. This is controlled by the
new configuration setting, $wgFragmentMode.
* $wgExperimentalHtmlIds is now deprecated and will be removed in a future version,
use $wgFragmentMode to migrate off it to a modern alternative.
* $wgExternalInterwikiFragmentMode was introduced to control how fragments in
sinterwikis going outside of current wiki farm are encoded.
* (T120333) Soft-deprecated the use of PHP extension 'mysql' in favor of 'mysqli'.
This PHP extension was deprecated in PHP 5.5 and removed in PHP 7.0. MediaWiki
auto-selects the 'mysqli' driver since MediaWiki 1.22, except if explicitly
requested through the configuration parameter $wgDBservers.
* $wgOOUIEditPage was removed, as it is now the default. This was documented as a
temporary variable during the migration period.
=== New features in 1.30 ===
* (T37247) Output from Parser::parse() will now be wrapped in a div with
class="mw-parser-output" by default. This may be changed or disabled using
ParserOptions::setWrapOutputClass().
* (T163562) Added ability to search for contributions within an IP ranges
at Special:Contributions.
* Added 'ChangeTagsAllowedAdd' hook, enabling extensions to allow software-
specific tags to be added by users.
* Added a 'ParserOptionsRegister' hook to allow extensions to register
additional parser options.
* (T45547) Included Pig Latin, a language game in English, as a
LanguageConverter variant. This allows English-speaking developers
to develop and test LanguageConverter more easily. Pig Latin can be
enabled by setting $wgUsePigLatinVariant to true.
* Added RecentChangesPurgeRows hook to allow extensions to purge data that
depends on the recentchanges table.
* Added JS config values wgDiffOldId/wgDiffNewId to the output of diff pages.
* (T2424) Added direct unwatch links to entries in Special:Watchlist (if the
'watchlistunwatchlinks' preference option is enabled). With JavaScript
enabled, these links toggle so the user can also re-watch pages that have
just been unwatched.
* Added $wgParserTestMediaHandlers, where mock media handlers can be passed to
MediaHandlerFactory for parser tests.
* Edit summaries, block reasons, and other "comments" are now stored in a
separate database table. Use the CommentFormatter class to access them.
** This is currently gated by $wgCommentTableSchemaMigrationStage. Most wikis
can set this to MIGRATION_NEW and run maintenance/migrateComments.php as
soon as any necessary extensions are updated.
* (T138166) Added ability for users to prohibit other users from sending them
emails with Special:Emailuser. Can be enabled by setting
$wgEnableUserEmailBlacklist to true.
* (T67297) $wgBrowserBlacklist is deprecated, and changing it will have no effect.
Instead, users using browsers that do not support Unicode will be unable to edit
and should upgrade to a modern browser instead.
=== External library changes in 1.30 ===

=== Bug fixes in 1.30 ===
* (T151633) Ordered list items use now Devanagari digits in Nepalese
(thanks to Sfic)
=== Action API changes in 1.30 ===
* (T37247) action=parse output will be wrapped in a div with
class="mw-parser-output" by default. This may be changed or disabled using
the new 'wrapoutputclass' parameter.
* When errorformat is not 'bc', abort reasons from action=login will be
formatted as specified by the error formatter parameters.
* action=compare can now handle arbitrary text, deleted revisions, and
returning users and edit comments.
* (T164106) The 'rvdifftotext', 'rvdifftotextpst', 'rvdiffto',
'rvexpandtemplates', 'rvgeneratexml', 'rvparse', and 'rvprop=parsetree'
parameters to prop=revisions are deprecated, as are the similarly named
parameters to prop=deletedrevisions, list=allrevisions, and
list=alldeletedrevisions. Use action=compare, action=parse, or
action=expandtemplates instead.
=== Action API internal changes in 1.30 ===
* ApiBase::getDescriptionMessage() and the "apihelp-*-description" messages are
deprecated. The existing message should be split between "apihelp-*-summary"
and "apihelp-*-extended-description".
* (T123931) Individual values of multi-valued parameters can now be marked as
deprecated.
=== Languages updated in 1.30 ===
MediaWiki supports over 350 languages. Many localisations are updated
regularly. Below only new and removed languages are listed, as well as
changes to languages because of Phabricator reports.
* Added: kbp (Kabɩyɛ / Kabiyè)
* Added: skr (Saraiki, سرائیکی)
* Added: tay (Tayal / Atayal)
* Removed: tokipona (Toki Pona)
==== Pig Latin added ====
* (T45547) Added Pig Latin, a made-up English variant (en-x-piglatin),
for easier variant development and testing. Disabled by default. It can be
enabled by setting $wgUsePigLatinVariant to true.
=== Other changes in 1.30 ===
* The use of an associative array for $wgProxyList, where the IP address is in
the key instead of the value, is deprecated (e.g. [ '127.0.0.1' => 'value' ]).
Please convert these arrays to indexed/sequential ones (e.g. [ '127.0.0.1' ]).

(for example, as '-<nowiki/>{') where it occurs inside template arguments
or wikilinks.
* (T163966) Page moves are now counted as edits for the purposes of
autopromotion, i.e., they increment the user_editcount field in the database.

manipulating Special:Log and Special:NewPages lines.
* The OldChangesListRecentChangesLine, EnhancedChangesListModifyLineData,
PageHistoryLineEnding, ContributionsLineEnding and DeletedContributionsLineEnding
hooks have an additional parameter, for manipulating HTML data attributes of
RC/history lines. EnhancedChangesListModifyBlockLineData can do that via the
$data['attribs'] subarray.
* (T130632) The OutputPage::enableTOC() method was removed.
* WikiPage::getParserOutput() will now throw an exception if passed
ParserOptions that would pollute the parser cache. Callers should use

escapeIdForLink().
* MagicWord::replaceMultiple() (deprecated in 1.25) was removed.

* EditPage::$mArticle and ::$mTitle are deprecated for public usage. The getters
::getArticle() and ::getTitle() should be used instead.
* Trying to control or fake EditPage context by overriding $wgUser, $wgRequest, $wgOut,
and $wgLang is no longer supported and won't work. The IContextSource returned from
EditPage::getContext() must be modified instead.
* Parser::getRandomString() (deprecated in 1.26) was removed.
* Parser::uniqPrefix() (deprecated in 1.26) was removed.
* Parser::extractTagsAndParams() now only accepts three arguments. The fourth,
$uniq_prefix was deprecated in 1.26 and has now been removed.
* (T172514) The following tables have had their UNIQUE indexes turned into proper
PRIMARY KEYs for increased maintainability: categorylinks, imagelinks, iwlinks,
langlinks, log_search, module_deps, objectcache, pagelinks, query_cache, site_stats,
templatelinks, text, transcache, user_former_groups, user_properties.
* IDatabase::nextSequenceValue() is no longer needed by any database backends

* DB_SLAVE is deprecated. DB_REPLICA should be used instead.
* wfUsePHP() is deprecated.
* wfFixSessionID() was removed.

== MediaWiki 1.29.1 ==
This is a maintenance release of the MediaWiki 1.29 branch.
The SpamBlacklist and PdfHandler extensions were missing from the generated
packages.
=== Changes since 1.29.1 ===
* (T164999) Define mw.Upload.Dialog.static.name in mediawiki.Upload.Dialog.js.
* (T172061) Fix fatal when passing a category to refreshLinks.php.
== MediaWiki 1.29.0 ==
=== Configuration changes in 1.29 ===
* Default cookie expiration time has been reduced to 30 days. Login cookie
expiration time is kept at 180 days.
* A new configuration variable has been added: $wgCookieSetOnAutoblock. This
determines whether to set a cookie when a user is autoblocked. Doing so means
that a blocked user, even after logging out and moving to a new IP address,
will still be blocked.
* The resetpassword right and associated password reset capture feature has
been removed.
* The $error parameter to the EmailUser hook should be set to a Status object
or boolean false. This should be compatible with at least MediaWiki 1.23 if
not earlier. Returning a raw HTML string is now deprecated.
* The $message parameter to the ApiCheckCanExecute hook should be set to an
ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
code for ApiBase::parseMsg() will no longer work.
* ApiBase::$messageMap is no longer public. Code attempting to access it will
result in a PHP fatal error.
* $wgUserEmailUseReplyTo is now true by default to work around restrictive DMARC
policies.
* Subpages are now enabled by default in the Template namespace. Set
$wgNamespacesWithSubpages[NS_TEMPLATE] to false to keep the old behavior.
* $wgRunJobsAsync is now false by default (T142751). This change only affects
wikis with $wgJobRunRate > 0.
* (T158474) "Unknown user" has been added to $wgReservedUsernames.
* (T156983) $wgRateLimitsExcludedIPs now accepts CIDR ranges as well as single IPs.
* $wgDummyLanguageCodes is deprecated. Additional language code mappings may be
added to $wgExtraLanguageCodes instead.
* (T161453) LocalisationCache will no longer use the temporary directory in it's
fallback chain when trying to work out where to write the cache.
* The user right 'editusercssjs' (deprecated in 1.16) was removed. Use
'editusercss' and 'edituserjs' in $wgGroupPermissions and elsewhere instead.
=== New features in 1.29 ===
* (T5233) A cookie can now be set when a user is autoblocked, to track that user
if they move to a new IP address. This is disabled by default.
* Added ILocalizedException interface to standardize the use of localized
exceptions, largely so the API can handle them more sensibly.
* Blocks created automatically by MediaWiki, such as for configured proxies or
dnsbls, are now indicated as such and use a new i18n message when displayed.
* Added new $wgHTTPImportTimeout setting. Sets timeout for
downloading the XML dump during a transwiki import in seconds.
* Parser limit report is now available in machine-readable format to JavaScript
via mw.config.get('wgPageParseReport').
* Added $wgSoftBlockRanges, to allow for automatically blocking anonymous edits
from certain IP ranges (e.g. private IPs).
* (T59603) Added new magic word {{PAGELANGUAGE}} which returns the language code
of the page being parsed.
* HTML5 form validation attributes will no longer be suppressed. Originally
browsers had poor support for them, but modern browsers handle them fine.
This might affect some forms that used them and only worked because the
attributes were not actually being set.
* Expiry times can now be specified when users are added to user groups.
* Completely new user interface for the RecentChanges page, which
structures filters into user-friendly groups. This has corresponding
changes to how filters are registered by core and extensions.
* The edit form now uses pretty OOjs UI buttons, checkboxes and summary input.
Because this change can cause problems for extensions and on-wiki
scripts depending on the exact HTML, the old version is still available
and can be used by setting $wgOOUIEditPage = false; in LocalSettings.php.
This will be removed later and OOjs UI will become the only option.
To make testing easier, users can also force either mode by adding
&ooui=true or &ooui=false to the action=edit URL.

* (T48143) SECURITY: Spam blacklist ineffective on encoded URLs inside file inclusion
syntax's link parameter.
* (T108138) SECURITY: Sysops can undelete pages, although the page is protected against
it.
=== Action API changes in 1.29 ===
* Submitting sensitive authentication request parameters to action=login,
action=clientlogin, action=createaccount, action=linkaccount, and
action=changeauthenticationdata in the query string is now an error. They
should be submitted in the POST body instead.
* The capture option for action=resetpassword has been removed
* action=clearhasmsg now requires a POST.
* (T47843) API errors and warnings may be requested in non-English languages
using the new 'errorformat', 'errorlang', and 'errorsuselocal' parameters.
* API error codes may have changed. Most notably, errors from modules using
parameter prefixes (e.g. all query submodules) will no longer be prefixed.
* ApiPageSet-using modules will report the 'invalidreason' using the specified
'errorformat'.
* action=emailuser may return a "Warnings" status, and now returns 'warnings' and
'errors' subelements (as applicable) instead of 'message'.
* action=imagerotate returns an 'errors' subelement rather than 'errormessage'.
* action=move now reports errors when moving the talk page as an array under
key 'talkmove-errors', rather than using 'talkmove-error-code' and
'talkmove-error-info'. The format for subpage move errors has also changed.
* action=revisiondelete no longer includes a "rendered" property on warnings
and errors for each item. Use errorformat=wikitext if you're wanting parsed
output.
* action=rollback no longer returns a "messageHtml" property. Use
errorformat=html if you're wanting HTML formatting of error messages.
* action=upload now reports optional stash failures as an array under key
'stasherrors' rather than a 'stashfailed' text string.
* action=watch reports 'errors' and 'warnings' instead of a single 'error', and
no longer returns a 'message' on success.
* Added action=validatepassword to validate passwords for the account creation
and password change forms.
* action=purge now requires a POST.
* There is a new `languagevariants` siprop for action=query&meta=siteinfo,
which returns a list of languages with active LanguageConverter instances.
* action=query&query=allpages will no longer filter redirects using a database
query in miser mode. This may result in less results being returned than were
requested.
=== Action API internal changes in 1.29 ===
* New methods were added to ApiBase to handle errors and warnings using i18n
keys. Methods for using hard-coded English messages were deprecated:
* ApiBase::dieUsage() was deprecated
* ApiBase::dieUsageMsg() was deprecated
* ApiBase::dieUsageMsgOrDebug() was deprecated
* ApiBase::getErrorFromStatus() was deprecated
* ApiBase::parseMsg() was deprecated
* ApiBase::setWarning() was deprecated
* ApiBase::$messageMap is no longer public. Code attempting to access it will
result in a PHP fatal error.
* The $message parameter to the ApiCheckCanExecute hook should be set to an
ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
code for ApiBase::parseMsg() will no longer work.
* UsageException is deprecated in favor of ApiUsageException. For the time
being ApiUsageException is a subclass of UsageException to allow things that
catch only UsageException to still function properly.
* If, for some strange reason, code was using an ApiErrorFormatter instead of
ApiErrorFormatter_BackCompat, note that the result format has changed and
various methods now take a module path rather than a module name.
* ApiMessageTrait::getApiCode() now strips 'apierror-' and 'apiwarn-' prefixes
from the message key, and maps some message keys for backwards compatibility.
* API parameters may now be marked as "sensitive" to keep their values out of
the logs.
=== Languages updated in 1.29 ===
MediaWiki supports over 350 languages. Many localisations are updated
regularly. Below only new and removed languages are listed, as well as
changes to languages because of Phabricator reports.
* Based as always on linguistic studies on intelligibility and language
knowledge by geography, language fallbacks have been expanded. When a
translation is missing in the user's preferred interface language, the
corresponding translation for the fallback language will be used instead.
English will only be used as last resort when there are no translations.
Some configurations (such as date formats and gender namespaces) have also
been updated when using the fallback language's configuration was inadequate.
The new or reinstated language fallbacks are (after cs ↔ sk in 1.28):
ca ↔ oc; hsb ↔ dsb; io → eo; mdf → ru; pnt → el; roa-tara → it; rup → ro;
sh → bs, sr-el, hr.
* (T137376) New language support: Atikamekw (atj).
* (T163600) New language support: Dinka (din).
* (T155957) Talk Namespaces for Javanese language (jv) have been updated.
==== No fallback for Ukrainian ====
* (T39314) The fallback from Ukrainian to Russian was removed. The Ukrainian
language will now use the default fallback language: English. When a translation
to Ukrainian is not available, an English string will be shown.

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

* User::getGroupName(), User::getGroupMember(), User:getGroupPage(),
User::makeGroupLinkHTML(), and User::makeGroupLinkWiki() were deprecated.
Use equivalent methods on the UserGroupMembership class.

and subclasses. It should only break if you call buildMainQueryConds
(changed to buildQuery with new signature) or doMainQuery (new
signature). Subclasses are likely to call at least doMainQuery
(possibly both), but other classes might too, because they were
public.
Also, some related hooks were deprecated, but this is not yet a
breaking change.
* Removed 'jquery.arrowSteps' module. (deprecated since 1.28)
* The 'jquery.autoEllipsis' ResourceLoader module is now deprecated.
* WikiRevision::$fileIsTemp was deprecated.
* WikiRevision::$importer was deprecated.
* WikiRevision::$user was deprecated.
* Article::getLastPurgeTimestamp(), WikiPage::getLastPurgeTimestamp(), and the
WikiPage::PURGE_* constants are deprecated, and the functions will always
return false. They were a hack for an issue that has since been fixed.
* Hook 'EditPageBeforeEditChecks' is now deprecated. Instead use the new hook
'EditPageGetCheckboxesDefinition', or 'EditPage::showStandardInputs:options'
if you don't actually care about checkboxes and just want to add some HTML
to the page.
* Selflinks are now rendered as href-less <a> tags with the class mw-selflink
rather than <strong> tags. The old class name, "selflink", was deprecated
and will be removed in a future release. (T160480)
* (T156184) $wgRawHtml will no longer apply to internationalization messages.
* Browser support for non-ES5 JavaScript browsers, including Android 2,
Opera <12.10, and Internet Explorer 9, was lowered from Grade A to Grade C.
* Removed wikibits global methods deprecated since MediaWiki 1.17 (T122755):
is_gecko, is_chrome_mac, is_chrome, webkit_version, is_safari_win, is_safari,
webkit_match, is_ff2, ff2_bugs, is_ff2_win, is_ff2_x11, opera95_bugs,
opera7_bugs, opera6_bugs, is_opera_95, is_opera_preseven, is_opera,
ie6_bugs, clientPC, changeText, killEvt, addHandler, hookEvent,
addClickHandler, removeHandler, getElementsByClassName, getInnerText,
setupCheckboxShiftClick, addCheckboxClickHandlers, mwEditButtons,
mwCustomEditButtons, injectSpinner, removeSpinner, escapeQuotes,
escapeQuotesHTML, jsMsg, addPortletLink, appendCSS, tooltipAccessKeyPrefix,
tooltipAccessKeyRegexp, updateTooltipAccessKeys.
* The ID of the <li> element containing the login link has changed from
'pt-login' to 'pt-login-private' in private wikis.
* The old, neglected "bulletin board style toolbar" in the edit form is now
deprecated (T30856). This old code dates from 2006, and was replaced in the
MediaWiki release tarball and in Wikimedia production by the WikiEditor
extension in 2010. It is only shown to users if no other editor was

== MediaWiki 1.28.2 ==
Due to a packaging error, the wrong version of the SyntaxHighlight extension was
included in the tarball version of MediaWiki 1.28.1. The version included had a
serious security issue in it (T158689). There was also some minor code fixes in
MediaWiki itself since 1.28.1, but none of them were security relevant.
== MediaWiki 1.28.1 ==
This is a security and maintenance release of the MediaWiki 1.28 branch.
=== Changes since 1.28.0 ===
* $wgRunJobsAsync is now false by default (T142751). This change only affects
wikis with $wgJobRunRate > 0.
* Fix fatal from "WaitConditionLoop" not being found, experienced when a wiki has
more than one database server setup.
* (T152717) Better escaping for PHP mail() command,
* (T154670) A missing method causing the MySQL installer to fatal in rare

* (T154872) Fix incorrect ar_usertext_timestamp index names in new 1.28 installs.
* (T109140) (T122209) SECURITY: Special:UserLogin and Special:Search allow redirect
to interwiki links.
* (T144845) SECURITY: XSS in SearchHighlighter::highlightText() when
$wgAdvancedSearchHighlighting is true.
* (T125177) SECURITY: API parameters may now be marked as "sensitive" to keep
their values out of the logs.
* (T150044) SECURITY: "Mark all pages visited" on the watchlist now requires a CSRF

* (T156184) SECURITY: Escape content model/format url parameter in message.
* (T151735) SECURITY: SVG filter evasion using default attribute values in DTD
declaration.

* (T48143) SECURITY: Spam blacklist ineffective on encoded URLs inside file inclusion
syntax's link parameter.
* (T108138) SECURITY: Sysops can undelete pages, although the page is protected against
it.
== MediaWiki 1.28 ==
=== Changes since 1.28.0-rc1 ===
* (T148957) Replace wgShowExceptionDetails with wgShowDBErrorBacktrace on db
errors.
* (T148956) Only apply wgDBschema to postgres/mssql.
* (T145991) Introduce separate log action for deleting pages on move.
* (T141474) (T110464) Bypass login page if no user input is required.
=== Changes since 1.28.0-rc0 ===
* (T142210) The changes to move the parser "NewPP limit report" from a HTML
comment to a machine-readable JavaScript config option 'wgPageParseReport'
have been undone. They caused the human-readable limit report to be shown
incompletely or not at all. ParserOutput::setLimitReportData() and
getLimitReportData() behave as they did in MediaWiki 1.27 again.
* (T149510) Value of {{DISPLAYTITLE:}} parser function will not be used for
the text of subheadings on a category page when creating it. This wasn't
working correctly.
* (T106793) MediaWiki will no longer try to perform a HTTP redirect to the
canonical pretty URL when a non-pretty URL is used. It resulted in redirect
loops in some clients and in some server configurations. This undoes a change
made in MediaWiki 1.26.
* (T149759) manifest_version: 2 was removed.
=== Configuration changes in 1.28 ===
* $wgSend404Code now affects status code of action=history if the page is not there.
* BREAKING CHANGE: $wgHTTPProxy is now *required* for all external requests
made by MediaWiki via a proxy. Relying on the http_proxy environment
variable is no longer supported.
* The load.php entry point now enforces the existing policy of not allowing
access to session data, which includes the session user and the session
user's language. If such access is attempted, an exception will be thrown.
* The number of internal PBKDF2 iterations used to derive the session secret
is configurable via $wgSessionPbkdf2Iterations.
* Upload dialog's file upload log comment can now be configured separately for
local and foreign uploads.
* $wgForeignUploadTargets now defaults to `[ 'local' ]`, where `'local'`
signifies local uploads. A value of `[]` (empty array) now means that
no upload targets are allowed, effectively disabling the upload dialog.
* The deprecated $wgEditEncoding variable has been removed; it was only used
for Esperanto language character conversion. You are now recommended to use
input methods provided by the UniversalLanguageSelector extension.
* When $wgPingback is true, MediaWiki will periodically ping
https://www.mediawiki.org/beacon with basic information about the local
MediaWiki installation. This data includes, for example, the type of system,
PHP version, and chosen database backend. This behavior is off by default.
* When $wgEditSubmitButtonLabelPublish is true, MediaWiki will label the button
to store-to-database-and-show-to-others as "Publish page"/"Publish changes";
if false, the default, they will be "Save page"/"Save changes".
* The 'editcontentmodel' permission is now granted to all logged-in users ('user').
instead of just administrators ('sysop'). Documentation for this feature is
available at <https://www.mediawiki.org/wiki/Help:ChangeContentModel>.
* $wgRevisionCacheExpiry is now set to one week by default instead of being disabled.
* Magic links are now disabled by default, and can be re-enabled by modifying the value
of $wgEnableMagicLinks. Their usage is discouraged, but if they are manually enabled,
a tracking category will be added to help identify usage and make it easier to migrate
away from. If you depend upon magic link functionality, it is requested that you comment
on <https://www.mediawiki.org/wiki/Requests_for_comment/Future_of_magic_links> and
explain your use case(s).
* New config variable $wgCSPFalsePositiveUrls to control what URLs to ignore
in upcoming Content-Security-Policy feature's reporting.
=== New features in 1.28 ===
* User::isBot() method for checking if an account is a bot role account.
* Added a new 'slideshow' mode for galleries.
* Added a new hook, 'UserIsBot', to aid in determining if a user is a bot.
* Added a new hook, 'ApiMakeParserOptions', to allow extensions to better
interact with API parsing.
* Added a new hook, 'UploadVerifyUpload', which can be used to reject a file
upload. Unlike 'UploadVerifyFile' it provides information about upload comment
and the file description page, but does not run for uploads to stash.
* (T141604) Extensions can now provide a better error message when their
maintenance scripts are run without the extension being installed.
* (T8948) Numeric sorting in categories is now supported by setting $wgCategoryCollation
to 'uca-default-u-kn' or 'uca-<langcode>-u-kn'. If you can't use UCA collations,
a 'numeric' collation is also available. If migrating from another
collation, you will need to run the updateCollation.php maintenance script.
* Two new codes have been added to #time parser function: "xit" for days in current
month, and "xiz" for days passed in the year, both in Iranian calendar.
* mw.Api has a new option, useUS, to use U+001F (Unit Separator) when
appropriate for sending multi-valued parameters. This defaults to true when
the mw.Api instance seems to be for the local wiki.
* After a client performs an action which alters a database that has replica databases,
MediaWiki will wait for the replica databases to synchronize with the master database
while it renders the HTML output. However, if the output is a redirect to another wiki
on the wiki farm with a different domain, MediaWiki will instead alter the redirect
URL to include a ?cpPosTime parameter that triggers the database synchronization when
the URL is followed by the client. The same-domain case uses a new cpPosTime cookie.
* Added new hooks, 'ApiQueryBaseBeforeQuery', 'ApiQueryBaseAfterQuery', and
'ApiQueryBaseProcessRow', to make it easier for extensions to add 'prop' and
'show' parameters to existing API query modules.
=== External library changes in 1.28 ===
==== Upgraded external libraries ====
* Updated es5-shim from v4.1.5 to v4.5.8
* Updated composer/semver from v1.4.1 to v1.4.2
* Updated wikimedia/php-session-serializer from v1.0.3 to v1.0.4
==== New external libraries ====
* Added wikimedia/scoped-callback v1.0.0
* Added wikimedia/wait-condition-loop v1.0.1
=== Bug fixes in 1.28 ===
* (T146496) action=history pages should return 404 HTTP error code if the page does not exist
* (T137264) SECURITY: XSS in unclosed internal links
* (T133147) SECURITY: Escape '<' and ']]>' in inline <style> blocks
* (T133147) SECURITY: Require login to preview user CSS pages
* (T132926) SECURITY: Do not allow undeleting a revision deleted file if it is
the top file
* (T129738) SECURITY: Make $wgBlockDisablesLogin also restrict logged in
permissions
* (T129738) SECURITY: Make blocks log users out if $wgBlockDisablesLogin is true
* (T139670) Move 'UserGetRights' call before application of
Session::getAllowedUserRights()
=== Action API changes in 1.28 ===
* Added 'maxarticlesize' property to action=query&meta=siteinfo which contains
the value of $wgMaxArticleSize.
* Property 'modulemessages' from action=parse&prop=modules was removed
(deprecated since 1.26).
* The following response properties from action=login, deprecated in 1.27, are
now removed: lgtoken, cookieprefix, sessionid. Clients should handle cookies
to properly manage session state.
* Submitting the lgtoken and lgpassword parameters in the query string to
action=login is now deprecated and outputs a warning. They should be submitted
in the POST body instead.
* Submitting sensitive authentication request parameters to action=clientlogin,
action=createaccount, action=linkaccount, and action=changeauthenticationdata
in the query string is now deprecated and outputs a warning. They should be
submitted in the POST body instead.
* (T141960) Multi-valued parameters may now be separated using U+001F (Unit Separator)
instead of the pipe character. This will be useful if some of the multiple
values need to contain pipes, e.g. for action=options.
* The API will now warn if input is not NFC-normalized Unicode or if it
contains invalid characters.
* The 'normalized' list output by action=query and other modules that use
ApiPageSet may contain entries where the 'from' value is percent-encoded as
the raw value cannot be represented in a valid API response. These are
indicated by a 'fromencoded' boolean alongside the existing 'from' parameter.
* (T28680) action=paraminfo can now return info about all submodules of a
module without listing them all explicitly.
* (T146770) It is now possible to assert that the current user is a specific
named user, using the 'assertuser' parameter.
* (T141963) Added a 'known' property when missing-but-known titles (e.g. from
the 'TitleIsAlwaysKnown' hook) are output in various modules.
=== Action API internal changes in 1.28 ===
* Added a new hook, 'ApiMakeParserOptions', to allow extensions to better
interact with ApiParse and ApiExpandTemplates.
* (T139565) SECURITY: API: Generate head items in the context of the given title
* (T115333) SECURITY: Check read permission when loading page content in ApiParse
* ApiBase::getResultData() was removed (deprecated since 1.25)
* ApiBase::makeHelpArrayToString() was removed (deprecated since 1.25)
* ApiBase::makeHelpMsgParameters() was removed (deprecated since 1.25)
* ApiBase::makeHelpMsg() was removed (deprecated since 1.25)

* ApiFormatBase::setHelp() was removed (deprecated since 1.25)
* ApiFormatBase::setUnescapeAmps() was removed (deprecated since 1.25)
* ApiMain::makeHelpMsgHeader() was removed (deprecated since 1.25)
* ApiMain::reallyMakeHelpMsg() was removed (deprecated since 1.25)
* ApiMain::setHelp() was removed (deprecated since 1.25)
* ApiResult::beginContinuation() was removed (deprecated since 1.25)
* ApiResult::cleanUpUTF8() was removed (deprecated since 1.25)
* ApiResult::convertStatusToArray() was removed (deprecated since 1.25)
* ApiResult::disableSizeCheck() was removed (deprecated since 1.24)
* ApiResult::enableSizeCheck() was removed (deprecated since 1.24)
* ApiResult::endContinuation() was removed (deprecated since 1.25)
* ApiResult::getData() was removed (deprecated since 1.25)
* ApiResult::getIsRawMode() was removed (deprecated since 1.25)
* ApiResult::setContent() was removed (deprecated since 1.25)
* ApiResult::setContinueParam() was removed (deprecated since 1.25)
* ApiResult::setElement() was removed (deprecated since 1.25)
* ApiResult::setGeneratorContinueParam() was removed (deprecated since 1.25)
* ApiResult::setIndexedTagName_internal() was removed (deprecated since 1.25)
* ApiResult::setIndexedTagName_recursive() was removed (deprecated since 1.25)
* ApiResult::setMainForContinuation() was removed (deprecated since 1.25)
* ApiResult::setParsedLimit() was removed (deprecated since 1.25)
* ApiResult::setRawMode() was removed (deprecated since 1.25)
* ApiResult::size() was removed (deprecated since 1.25)
* Added new hooks, 'ApiQueryBaseBeforeQuery', 'ApiQueryBaseAfterQuery', and
'ApiQueryBaseProcessRow', to make it easier for extensions to add 'prop' and
'show' parameters to existing API query modules. A query module can enable
these hooks by passing an array for $hookData to ApiQueryBase::select() and
by calling ApiQueryBase->processRow() before adding a row's data to the
result.
=== Languages updated in 1.28 ===
MediaWiki supports over 375 languages. Many localisations are updated
regularly. Below only new and removed languages are listed, as well as
changes to languages because of Phabricator reports.

* Linker::link() and Linker::linkKnown() were deprecated; please instead use
MediaWiki\Linker\LinkRenderer. In addition, the LinkBegin and LinkEnd hooks
were replaced by HtmlPageLinkRendererBegin and HtmlPageLinkRendererEnd
respectively. See docs/hooks.txt for the specific changes needed for those hooks.
* Linker::formatSize() was deprecated. Use Language::formatSize() directly.
* Aliases for Linker methods, deprecated since 1.21, were removed from Skin:
* Skin::commentBlock() (use Linker::commentBlock() instead)

on requests needed by primary providers even if all primaries need them.
Primary providers are discouraged from returning multiple REQUIRED requests.

will no longer be automatically infused. You should call `OO.ui.infuse()`
on them yourself from your JavaScript code.
* parserTests.php has moved to tests/parser/parserTests.php
* The command line options specific to parser tests have been removed from
phpunit.php: --regex and --keep-uploads. Instead of --regex, use --filter.
Instead of --keep-uploads, use the same option to parserTests.php, but you
must specify a directory with --upload-dir.
* The 'jquery.arrowSteps' ResourceLoader module is now deprecated.
* IP::isConfiguredProxy() and IP::isTrustedProxy() were removed. Callers should
migrate to using the same functions on a ProxyLookup instance, obtainable from
MediaWikiServices.
* The ArticleAfterFetchContent, ArticleInsertComplete, ArticleSave, ArticleSaveComplete,
ArticleViewCustom, EditFilterMerged, EditPageGetDiffText, EditPageGetPreviewText and

== Compatibility ==
MediaWiki 1.28 requires PHP 5.5.9 or later. There is experimental support for
HHVM 3.6.5 or later.
MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
support for them is somewhat less mature. There is experimental support for
Oracle and Microsoft SQL Server.
The supported versions are:
* MySQL 5.0.3 or later
* PostgreSQL 8.3 or later
* SQLite 3.3.7 or later
* Oracle 9.0.1 or later
* Microsoft SQL Server 2005 (9.00.1399)
== Upgrading ==
1.28 has several database changes since 1.27, and will not work without schema
updates. Note that due to changes to some very large tables like the revision
table, the schema update may take quite long (minutes on a medium sized site,
many hours on a large site).
If upgrading from before 1.11, and you are using a wiki as a commons
repository, make sure that it is updated as well. Otherwise, errors may arise
