Dev channel - Give extension developer more reaction time

[KohakuBlueleaf]

I think it is important to have something like dev channel/stable channel .etc
Since some change may cause tons of extension been broken and user actually doesn't know which part goes wrong.

Please add something like dev channel for developers to have time to catch up the newest update.

I agree, many people are hesitant to update because extensions break all the time

Somehow, this is a MUST...
