Added new form field widget called repeater for repeatable fields (see Backend > Forms docs).

Made some UI improvements to the Rich Editor.

Form widget base class no longer takes a model as the 2nd argument, it should be passed as model in the configuration instead.

Introduce AjaxException that allows response contents to be sent to framework.js and still be treated as an error.

Report Widgets now support the use of AJAX event handlers.

Fixes an intermittent issue where a CmsXXX_XXXClass cache class cannot be found and throws a fatal error.

Added new form field type section for dividing groups of other fields (see Backend > Forms docs).

The back-end code editor now supports the use of Emmet.

Added the ability to prune Event and Request log records.

The /uploads directory has been moved to /storage/app/uploads to make way for CDN support. This directory should be moved on the file system and the config (cms.storage.uploads.path) updated.

For security reasons a vague error message is shown when a user tries to sign in unsuccessfully and the setting app.debug is disabled.

Added "Auto close tags and special characters" to Code editor preferences.
