RText 2.0.0-beta2 was just released on SourceForge! Why wasn’t there a “beta 1″? Well, this release includes RSTA 2.0-beta2, and I wanted to keep their version numbers in sync, so there was no beta 1. RText is an example of a full-featured application that takes advantage of everything RSyntaxTextArea has to offer. Keep in mind though that this release is built on top of a beta release of RSTA, and there may be more bugs than usual (or maybe not!).
In any case, enjoy!
