1) What's New
For this release, we have focused on making #develop work on both .NET 1.0 and 1.1. Please note that the install application for this and upcoming releases will be .NET 1.1 only - if you want to run #develop on .NET 1.0, you have to download the source
code and compile yourself. No major new features except for the exception dialog box (we hope you don't see it too often), our current focus is on making #develop portable to other CLR's and platforms (more on this in the next section).
2) The Porting Effort
The reason why you haven't seen major cool new features recently is that we are busy working on porting #develop from Windows Forms to #WT (Sharp Widget Toolkit). This change in UI toolkits will allow us to run with native look and feel on MS .NET / Windows, Mono / Windows, Mono / Linux, etc in the future, and we expect the next major release to be already based on the new codebase.
