+* MediaWiki no longer has a 'JavaScript-powered' wikitext toolbar built in. The
+ old "bulletin board style toolbar", known as "the 2006 wikitext editor", has
+ been removed, and instead sysadmins will be required to choose one (or more)
+ of the several extensions available for this purpose if they need the
+ functionality. The MediaWiki "tarball" releases have included the replacement
+ extension for this, the WikiEditor extension aka "the 2010 wikitext editor",
+ for many years now. As part of this, several parts of MediaWiki have been
+ removed or simplified:
+ * The user option 'showtoolbar' (shown as "Show edit toolbar") is no longer
+ available; if an extension adds a toolbar via the EditPageBeforeEditToolbar
+ hook, it will be shown; extensions should provide a specific user preference
+ to disable themselves as needed.
+ * The public methods Language::getImageFile() and ::getImageFiles(), and the
+ related specification of $imageFiles within individual languages' code file,
+ as well as the referenced static media assets, all of which were only used
+ inside MediaWiki itself for providing the icons for the old toolbar, have
+ been removed without explicit deprecation.
+ * The internal ResourceLoader module "mediawiki.toolbar", which is unused
+ except by MediaWiki itself and back-compatibility code, has been removed.
+ * The internal ResourceLoaderEditToolbarModule class has been removed.
