do you need to bump up the version?

What do you mean?

[Adminiuga]

I don't think it got successfully published to pypi. Not sure if it was because of the version.
Let me know when it's ready to be updated in homeassistant.

How's the process of getting the new release integrated in HA core?
Will it still be necessary to repair everything as mentioned in #58 (comment) ?

You can test a new release yourself as per the instructions in -> https://github.com/zigpy/zigpy-cc/blob/master/README.md

For a new release to make in into a new release of upstream HA core for everyone you will have to wait for the devs to do a PR.

@lociii I've added a migration guide to the Readme if you don't want to repair your devices
