We are preparing a few releases that will enhance version 2.4 and will bring the following features:
Improved export dialog which can minify your source files and remembers where each design was exported (see the forum thread).
More beautiful built-in components, and hopefully new templates.
Global meta tags, shared by all pages.
Bug fixes and performance improvements.
Version 2.4.1 was released on September 14th, and it fixed some issues with the built in components and the Downloaded group, and added the ability to copy valid CSS code by selecting it in the editor.
Version 2.4.2 was released on October 5th, and brought the new Export dialog with minification and CDN support. See the release post here.
Version 2.4.3 was released on October 12th, and brought the ability to set the jQuery version that your design uses and the global meta tags, shared by all pages. In it we also delivered a new Settings dialog which combines many settings for your designs in a single place.
Version 2.4.5 was released on November 22nd, and added @keyframes support and improvements to the CSS editing experience. See the release post.
Version 2.5 will be the next release. It should be out around December 16th.It is out.
