I'm pleased to announce the release of PolymerTS version 0.2.3. PolymerTS makes it easy to write Polymer 1.x applications (or components) with TypeScript, and provides a set of decorators to simplify the development process.
A few months ago I joined the project as a collaborator, and I've been thrilled to finally have the time to make some major contributions. In addition fixing a problem with observers in the previous release, this release also cleans up the project structure and adds contribution info.
In addition, I'll be working with the community and my clients to come up with a migration path for Polymer 2 so that developers can upgrade their applications from Polymer 1.x + TypeScript + PolymerTS to Polymer 2.x + TypeScript + PolymerDecorators (the new official TypeScript project from the Polymer team). If you're interested in helping, please comment on the github issue.
