This is a pre-release version, so do not use it on mission-critical work. If you are using Balsamiq Mockups 2, you don't need to uninstall it, this version will run side-by-side with it.
New builds are published above after each check-in, so come back and update often!
If you find any issues or have any comments, please use the Help > Send Feedback menu in Mockups to comment in the Balsamiq Forums. We'll see you there!
If you're looking for the latest stable release, you can find it on the Download page.
