The focus of the Alpha is Fusebox 4.1 compatibility. I consider that part to be "feature complete".

Custom lexicons and custom attributes (on circuit and fuseaction tags) are about 95% feature complete right now and there are a number of enhancements incorporated in Alpha 1. Alpha 2 may contain one or two more enhancements but it will mostly just be bug fixes for Alpha 1 ready for the wider audience.

Beta 1 will happen in about a month and will be the time to really start banging away on the new features in Fusebox 5. I will have plenty of good documentation by that time to help testers. Again, Beta 1 will be available only to members of the Fusebox 5 mailing list.

At this point I want to call out Mike Ritchie and Jared Rypka-Hauer for very useful feedback and an early sanity check on the core files.

For what it's worth, this blog is running on Alpha 1, as is most of the rest of corfield.org. Let me know if you see anything weird happening with the blog this week (some of you will have seen occasional breakages today as I was testing pre-Alpha builds).
