If you run Bloom on the beta channel, you are a crucial part of the Bloom team. Your help ensures that folks who don’t have easy access to technical support get a solid product when the beta becomes the release version. Thank you!
If you already have a beta version, Bloom will automatically ask to update itself. Otherwise, you can get the beta from the Bloom downloads page. As usual, you can have the Release & Beta versions installed at the same time, and open books on either.
