Public Beta Releases

In order to try to improve our testing, we're going to start doing a "Public Beta" period for new releases.

We'll test to the point we normally would before a release, then make the new version available here for anyone who wants to try it.  We'll gather feedback from those users to try to fix any issues we missed before doing a general release.

Reporting Bugs

If you encounter a bug in a public beta, please let us know by sending an email to with as much information as you can recall about what you were doing so we can try to reproduce it and fix it.

The standard licensing rules apply - you'll need to have a current license key to run these (or be in an active trial period).  If you have any issues while using a beta, you can just install whatever version you were using before, or grab the current released version from the Trial/Download page.


Public Betas can be downloaded from here.
