Yesterday we took what was supposed to be the final change into Deer Park Alpha 1 - the change to the theme and extension version from what we had on the 1.0 branch. This caused some fallout and we're looking for additional testing to make sure there aren't any unknowns in the area of extension updating.
Please grab one of the builds below and give it a whirl. If you find any additional problems with extension or theme update or install, please let me know here. Thanks.
