The TextUML Toolkit 1.2 is now available, 5 months after 1.1, when it first became an open source project. If you already got RC2 (1.2.0.200902011417), it is the same build, no need to upgrade again. Otherwise, just point the Eclipse update mechanism to:

Please see the feature page for a summary of the evolution of the TextUML Toolkit in terms of features across releases.

As usual, bug reports and feature requests are dearly appreciated. And if you need help, make sure to ask on the forum.
