will now truly work out of the box, as long as your users can connect to upload.wikimedia.org: thumbnails will be served from that domain instead of requiring local generation (251556).

More documentation translation
Works continues on the migration to the Translate extension, now used by about 3000 pages. The size of translations text increased by various megabytes. Thanks go to our tireless translation administrators and translators but also to Google Code-in 2015 students, in particular IoannisKydonis who migrated thousands of translations including the entire Manual:FAQ.

 * If the  and   PHP extensions are both unavailable, secure session storage (used for login) will raise an exception. This exception may be bypassed by setting  . Note that this bypass is not recommended. It is insecure. You should not use it.
 * The RandomRootPage extension has been merged into MediaWiki core. If you have it installed, you should uninstall it.
 * The ApiSandbox extension has been merged into MediaWiki core. If you have it installed, you should uninstall it.
 * is deprecated and always true, and thus sessions are no longer stored using PHP's session handling (e.g. ). If you see issues with loss of session data while logging in, ensure you have a persistent shared cache configured for session storage in.
