production.
=== Configuration changes in 1.26 ===
+* $wgEnableParserCache was deprecated, set $wgParserCacheType to CACHE_NONE
+ instead if you want to disable the parser cache.
=== New features in 1.26 ===
* Change tags can now be hidden in the interface by disabling the associated
"tag-<id>" interface message.
* ':' (colon) is now invalid in usernames for new accounts. Existing accounts

+* Added a new hook, 'LogException', to log exceptions in nonstandard ways.
==== External libraries ====
one function. The callback can't be called directly any more. The callback
function is replaced with confirmCloseWindow.release().
* Removed maintenance script deleteImageMemcached.php.
+* MWFunction::newObj() was removed (deprecated in 1.25).
+ ObjectFactory::getObjectFromSpec() should be used instead.
+* The parser will no longer randomize the string it uses to mark the place of
+ items that were stripped during parsing. It will use a fixed string instead.
+ This causes the parser to re-use the regular expressions it uses to search
+ and replace markers rather than generate novel expressions on each parse.
+ Re-using regular expressions will improve performance on HHVM and the
+ forthcoming PHP 7. The interfaces changes accompanying this change are:
+ - Parser::getRandomString() and Parser::uniqPrefix() have been deprecated.
+ - The $uniq_prefix argument for Parser::extractTagsAndParams() and the
+ $prefix argument for StripState::_construct() are deprecated and their
+ value is ignored.
