wintercms/winter v1.0.452 on GitHub

UX/UI Improvements:

Force values that would overflow a .form-control container to wrap to the next line instead of overflowing the field
Fixed minor visual glitch in the Insert URL popup of Froala

Added oc.inputPreset.beforeUpdate JS event to the input.preset.js logic
Added support for optional $options parameter to the FormController's formRenderField($name, $options) method to be passed to the Form widget's renderField($name, $options) method.
Added role="form" attribute to output of Form::open()
Added automatic conversion of array notation to dot notation in validation rules (attribute[nested] to attribute.nested, etc)
Added cache attribute to attributes supported by addJs($script, $attributes) to enable disabling the CloudFlare RocketLoader which causes issues in the backend.
Simplified how the Repeater FormWidget works internally which should resolve some sporadic issues.
Now using an embedded Form widget to process FileUpload file properties (like title and description). This enables dynamic extension of this form.
Added automatic mimetype detection of .svg files as image/svg+xml
Added relationGetManageWidget() and relationGetViewWidget() methods to the RelationController behavior.
Added hasFatalError() and getFatalError() methods to the ErrorMaker trait
Return 404 when attempting to visit /error directly when debug mode disabled
Added ability to make wildcard URL parameters optional.
Added support for morphOne relations in backend list columns

Fixed issue with the DataTable FormWidget being unable to dynamically get dropdown options
Fixed issue where Form widgets attached to the CMS backend controller would have a different alias on every request causing features that relied on consistent aliases to break (namely grouped repeaters in the CMS / RainLab.Pages section)
Fixed issue where the text filter used a hardcoded widget alias instead of getEventHandler()
Fixed issue where when inserting an image with the mediafinder into a richeditor field, the image could sometimes be inserted at the top of the content instead of where the cursor was when it was originally selected
Fix ability to clear RecordFinder fields when useRelation is set to false
Fixed issues introduced in Build #449 with regards to the "Image not found" message showing up at incorrect times for the MediaFinder formwidget
Fixed a bug where track-input triggered requests could return incorrect results by waiting until input is finished to fire requests triggered by tracking input
Fixed bug where inserting a link reference to a home page (/) in the RichEditor through the page selection dialog would actually insert an empty link reference instead.
Fixed issue where a scheduled command could be run before the database is initially populated which could cause issues if that command attempted to access the database.
Fixed support for Laravel's automatic package discovery feature

Prevent public functions on backend ControllerBehaviors from being run as controller actions unless intended to do that.

Added preloading of all essential scripts in the backend to improve performance
Improved performance when utilizing remote storage drivers by caching the results of hasFile().
Cached the parsed theme configuration to improve performance on subsequent page loads
