So a new version of the Celtx screenwriting/pre-production software has been released. Version 2.5 offers several new features, including "Revision Mode" which locks page numbers while you make edits, Text Lock Mode, a Sketch tool to add images to the project, Studio Collaboration which is an integrated text messaging service for Studio users, and new options for PDF formatting. Celtx is available for Mac, Linux, and Windows in over 30 languages at no cost.

Update 11/15/09: 2.5.1 Released. Bugs addressed:

1. Windows crashes when canceling add image dialog. If you cancel the add image dialog when adding an image using the media sidebar or a catalog form Celtx crashes. (Windows only)

2. Using Print Preview disables all subtabs. Once you have select print preview the subtabs are no longer responsive. You have to close and re-open the application to fix this problem. (Windows and Linux)

3. Windows registry not updated correctly for NEW Celtx installations. The windows installer doesn't correctly register the celtxs protocol for new installs. This would prevent first time Celtx user from installing addons and open projects from the studio. (Windows only)
