This release comes with a packaged Wodo.CollabTextEditor product, which is the Wodo editor component for collaborative text editing. It also introduces support for annotations in collaborative mode, removes some editing regressions introduced by changes in Browser APIs. Also of note is improved compression in generated documents (which should be much, much smaller now) thanks to JSZip, a javascript library for creating, reading, and editing ZIP files.
Deployers are recommended to go to the Download page and update their deployment of webodf.js or the Wodo.TextEditor. Also, check out the demos (general, features).
