If the designer of a tools explicitly says, "It's in Beta!", then it's fine as I will expect it to change, and there's a possibility of influencing that change. :D
But, if it's a full release, and the updates break the existing workflow, then why would I bother trusting it in future?
Especially when it's commercial software, as the people making those decisions are doing the exact opposite of what their job is supposed to be... :|
