The Escapers has released Flux 3.1.4 (http://theescapers.com/flux2/), an update of the Mac OS X app that allows drag ‘n drop creation of web pages without the need of knowledge of XHTMLICSS (though you can twiddle with the code if you like). The upgrade offers better support for the Lively Coda Plugin.
Snapshots can be easily created using a keyboard shortcut. Also, a new palette manages the complete history of your web page.
Users of both Flux 1 & 2 are entitled to an upgrade for £34.99, and new users can pay £69.99 for a single user license, or £99.99 for a family license.
