You can read the What's New in 1.6 wiki page to learn about the recent additions. I had already used the publish/subscribe listener invocation (more like Model-Glue), the improved Application.cfc integration and the ColdSpring Property (which replaces the old Plugin). The major new features in 1.6 are caching and logging which were not in the early build I was using, unfortunately (for me!).

Official support is provided for Adobe ColdFusion MX 7 / 8, Open BlueDragon 7+, New Atlanta BlueDragon 7+ (but not BlueDragon.NET - which I was a bit surprised by). They're hoping to add official support for Railo soon - but have heard that it runs just fine on that engine.

1) None of Team Mach-II uses BD.net 2) Due to #1, we don't test on BD.net 3) We do not know of anybody that has used or wants to use Mach-II on BD.net 4) We do use several Java classes such a string buffers and hash sets among other things and their support on BD.net's C# java equivalents is unknown.

Glad you liked the features in 1.6 Sean. Even more exciting stuff in 1.8 such as loading page-views by convention using view loaders, packages, toolkit improvements (bundled plugins, properties, event-filters) and the ability to reload a single listener (filter, plugin or property) from the Mach-II dashboard without having reload the entire framework. Some of these things are already in the 1.8 BER.
