 * and were removed, now always enabled. If you use RDFa on your wiki, you now have to explicitly set  to 'HTML+RDFa 1.0' or 'XHTML+RDFa 1.0'.
 * was removed.
 * Deprecated and, because there was little value in making the behavior configurable. The default values (`false` for the former, 1000 for the latter) are now hard-coded.
 * was removed.
 * was removed.
 * has been removed, as it provides functionality only used by custom Wikimedia patches against Squid 2.x that probably noone uses in production anymore. There is now that provides similar functionality but instead of the MediaWiki-specific X-Vary-Options header, uses the draft Key header standard.
 * (and support for '.php5' entry points) was removed. See the deprecation notice in the release notes for version 1.25 for advice on how to preserve support for '.php5' entry points via URL rewriting.
 * Password handling via the User object has been deprecated and partially removed, pending the future introduction of AuthManager. In particular:
 * expirePassword, getPasswordExpireDate, resetPasswordExpiration, and getPasswordExpired have been removed. They were unused outside of core.
 * The mPassword, mNewpassword, mNewpassTime, and mPasswordExpires fields are now private and will be removed in the future.
 * The getPassword and getTemporaryPassword methods now throw BadMethodCallException and will be removed in the future.
 * The ability to pass 'password' and 'newpassword' to createNew has been removed. The only users of it seem to have been using it to set invalid passwords, and so shouldn't be greatly affected.
 * setPassword, setInternalPassword, and setNewpassword have been deprecated, pending the introduction of AuthManager.
 * User::randomPassword is deprecated in favor of a new method PasswordFactory::generateRandomPasswordString
 * User::getPasswordFactory is deprecated, callers should just create a PasswordFactory themselves.
 * A new constructor, User::newSystemUser, has been added to simplify the creation of passwordless "system" users for logged actions.
 * was removed.
 * was removed. This is now enabled by default.
 * now hotlinks Commons images by default instead of downloading originals and thumbnailing them locally. This allows wikis to save on CPU and bandwidth while reducing time to first byte for pages, even without a thumbnail handler. See documentation for tweaks.
 * WebP is enabled by default as an uploadable filetype.
 * must now be either a full url, or start with a "/".
 * was removed; use ['ratelimit'] instead.

 * Massive overhaul to session handling:
 * is no longer supported and must be true, due to MediaWiki\Session\SessionManager. is similarly no longer used.
 * ObjectCacheSessionHandler is removed, replaced with MediaWiki\Session\PhpSessionHandler.
 * PHP session handling in general ($_SESSION, session_id, and so on) is deprecated. Use MediaWiki\Session\SessionManager instead. A new config variable,, is available to cause use of $_SESSION to issue a deprecation warning or to cause most PHP session handling to throw exceptions.
 * Deprecated UserSetCookies hook. Session-handling extensions should generally be creating a custom subclass of CookieSessionProvider. Other extensions messing with cookies can no longer count on user data being saved in cookies versus other methods.
 * Deprecated UserLoadFromSession hook, extensions should create a MediaWiki\Session\SessionProvider.
 * The User cannot be loaded from session until after Setup.php completes. Attempts to do so will be ignored and the User will remain unloaded.
 * CSRF tokens may be fetched from the MediaWiki\Session\Session, which uses the MediaWiki\Session\Token class.

 * Deprecated AuthPluginAutoCreate hook in favor of LocalUserCreated.
 * Most cookie-handling methods in User are deprecated.
 * and $wgCopyUploadAsyncTimeout were removed. This was an experimental feature that has never worked.

 * was removed . Extensions, skins, gadgets and scripts that use the mediawiki.util module must express a dependency on it.

 * Removed configuration option . Use ['copyright']['copyright'] instead.
 * If the openssl and mcrypt PHP extensions are both unavailable, secure session storage (used for login) will raise an exception. This exception may be bypassed by setting = true.
 * Massive overhaul to authentication:
 * AuthPlugin and AuthPluginUser are deprecated.
 * LoginForm and associated templates are deprecated. Extensions which called static LoginForm methods should be converted into authentication providers.
 * The following hooks are deprecated:
 * AbortAutoAccount (create a MediaWiki\Auth\PreAuthenticationProvider instead)

 * AbortNewAccount (create a MediaWiki\Auth\PreAuthenticationProvider instead)
 * AddNewAccount (use LocalUserCreated instead)

새로운 기능

 * was also added. This decides how long a user sticks to the primary DC (via cookies) after they make changes to the site.
 * Added a new hook, 'UserMailerTransformContent', to transform the contents of an email. This is similar to the EmailUser hook but applies to all mail sent via UserMailer.
 * Added a new hook, 'UserMailerTransformMessage', to transform the contents of an emai after MIME encoding.
 * Added a new hook, 'UserMailerSplitTo', to control which users have to be emailed separately (ie. there is a single address in the To: field) so user-specific changes to the email can be applied safely.
 * was added, which limits the CDN cache TTL when any load balancer uses a DB that is lagged beyond the 'max lag' setting in the relevant section of.
 * User::newSystemUser may be used to simplify the creation of passwordless "system" users for logged actions from scripts and extensions.
 * Extensions can now return detailed error information via the API when preventing user actions using 'getUserPermissionsErrors' and similar hooks by using ApiMessage instances instead of strings for the $result value.
 * was added to limit bot changes when databases lag becomes too high.
 * Skins and extensions can now use FlexBox mixins (.flex-display(@display: flex) and .flex(@grow: 1, @shrink: 1, @width: auto, @order: 1)) in Less to create cross-browser-compatible FlexBox rules. Users will still need to add fallback float rules or the like for compatibility with IE9- separately.
 * Added MWTimestamp::getTimezoneString which returns the localized timezone string, if available. To localize this string, see the comments of in includes/DefaultSettings.php.
 * Added CentralIdLookup, a service that allows extensions needing a concept of "central" users to get that without having to know about specific central authentication extensions.
 * added to limit huge user-generated transactions. Regular web request transactions that takes longer than this are aborted.
 * Added a new hook, 'TitleMoveCompleting', which runs before a page move is committed.
 * was added to provide secondary delayed purges of URLs from CDN to mitigate DB replication lag and WAN cache purge lag.
 * Installer will default to setting CACHE_ACCEL as the main cache type if it is available.
 * It is now possible to patrol file uploads (both for new files and new versions of existing files). Special:NewFiles has gained an option to filter by patrol status. This functionality can be disabled using.
 * MediaWiki\Session infrastructure allows for easier use of session mechanisms other than the usual cookies.
 * SessionMetadata and SessionCheckInfo hooks allow for setting and checking custom session metadata.
 * Added MWGrants and associated configuration settings and  to hold configuration for authentication features such as OAuth that want to allow restricting the user rights a user may make use of.
 * If you're already using the OAuth extension, these new variables are identical to (and will replace) and.
 * Added MWRestrictions as a class to check restrictions on a WebRequest, e.g. to assert that the request comes from a particular IP range.
 * Added bot passwords, a rights-restricted login mechanism for API-using bots.
 * Whitelisted the following HTML attributes for all elements in wikitext: aria-describedby, aria-flowto, aria-label, aria-labelledby, aria-owns.
 * Removed "presentation" restriction on the HTML role attribute in wikitext. All values are now allowed for the role attribute.
 * now also supports callbacks to create an instance of the appropriate ContentHandler subclass.
 * Added, which if non-null prevents the user_token database field from being exposed in cookies. Setting this would be a good idea, but will log out all current sessions.
 * was added, for managing PubSub event relay configuration, specifically for reliable CDN url purges.
 * Requests have unique IDs, equal to the UNIQUE_ID environment variable (when MediaWiki is behind Apache+mod_unique_id or something similar) or a randomly- generated 24-character string. This request ID is used to annotate log records and error messages. It is available client-side via mw.config.get( 'wgRequestId' ). The request ID supplants exception IDs. Accordingly, MWExceptionHandler::getLogId is deprecated.
 * Add a preference for watching uploads by default, also applies to API-based upload tools.
 * was added to override chroma subsampling for JPEG image thumbnails created via ImageMagick. Defaults to 'yuv420', providing bandwidth savings versus the previous behavior on many files.
 * MediaWiki\Auth infrastructure (called "AuthManager") allows for more flexible configuration of multiple authentication pieces that was possible with AuthPlugin. For example, it's now easy to plug in second-factor authentication, or add additional checks to the login process, or to support multiple login methods at once, or to support non-password-based login methods.
 * Providers are configured via the global setting.
 * New hook, AuthChangeFormFields, to adjust the form fields on AuthManager-related special pages.
 * New hook, AuthManagerLoginAuthenticateAudit, for additional logging of AuthManager-related authentication requests.
 * New hook, ChangeAuthenticationDataAudit, for additional logging of AuthManager-related authentication data changes.
 * New hook, SecuritySensitiveOperationStatus, to work with the new mechanism for requiring a recent login before taking security-sensitive operations like changing a password.
 * Two new globals, and  can be used to prevent the web UI and the API changing certain authentication data.
 * The file upload dialog (available if you install WikiEditor or VisualEditor) can now be configured using.

호환성
미디어위키 1.27은 PHP 5.5.9 이상을 필요로 합니다. HHVM 3.6.5 이상 버전 또한 실험적으로 지원하고 있습니다.

데이터베이스 MS로 MySQL이 추천됩니다. PostgreSQL이나 SQLite도 쓰일 수 있지만, 이들 지원은 덜 성숙되어 있습니다. Oracle이나 Microsoft SQL Server 또한 실험적으로 지원하고 있습니다.

지원되는 버전들은 다음과 같습니다:


 * MySQL 5.0.3+
 * PostgreSQL 8.3+
 * SQLite 3.3.7+
 * Oracle 9.0.1+
 * Microsoft SQL Server 2005 (9.00.1399)

업그레이드
1.27 has several database changes since 1.26, 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 due to database schema changes.

If upgrading from before 1.7, you may want to run refreshLinks.php to ensure new database fields are filled with data.

If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed with MediaWiki 1.21.

Don't forget to always back up your database before upgrading!

See the file UPGRADE for more detailed upgrade instructions.

For notes on 1.26.x and older releases, see HISTORY.
