I have run 2.0b11 since the day it came out, and I grab every hijack release as soon as I can, and I have no day-to-day issues. There are some small workarounds such as not sync-ing twice and not uploading many gigabytes in one session, but thaey are not a real issue.
And remember a worst case scenario just involves reloading version 1 again. Very easy.
