Sorry for not signing CLA at the first time, I have already sign the CLA and finished rescan, but the #333 (comment) is still showing 🤔

The cla/google check seems to be green, so I believe you should be good.

Edit: Sorry, just noticed, but the changelog entry should go under a new section 1.2.0-wip. 1.1.0 has already been released.

This should go under a new section 1.2.0-wip as 1.1.0 has been released already.
