Release Notes: This release has a focus on bugfixes and other cleanups after the big changes that went into 3.3.0. New functionality includes support for TinyMCE 4 in WTextEdit and a CSS stylesheet parser (and many other improvements) in the HMTL-to-PDF renderer.
Release Notes: Twitter Bootstrap was adopted as a new theme in addition to the existing CSS-based themes. As a result, several new widgets were added (toolbar, navigation bar, split button, and date edit) and improved (menus and popup menus). The widget gallery has undergone a complete rework.
