Yes the ALPHA ZXP will always install the latest release. I will rename and take down the ALPHA zxp if it becomes out of date.
I've been posting to the forum when I do updates. I can add a thread to the forum to specifically call out the last update date to help you keep track. Thanks for the advice. I'll add that with the next update.
I'm going to keep it in BETA until there aren't any known issues. Currently I know there are issues with multiple insert, multiple update, manage relational table, and the file manager that need to be addressed. Once those are fixed then I'll continue internal testing and if no issues are found by me or beta testers for two weeks, then I'll push the live version.
