Current work around for others affected - people can use my branch:
pip install git+https://github.com/ianfhunter/commentjson.git@patch-1

I will delete this after merged

Sorry about that! I reverted the change in 0.8.1 (already released), and will use a major version for such a change next time.

Hi @erezsh, what you did in lark-parser is correct according to SemVer, prior to 1.0.0 anything can change at any time as the API is explicitly unstable. It’s commentjson not constraining the dependency correctly.

That said, thanks for reverting, as that will help until commentjson can fix things.

No worries, Thanks for the revert :)

Hey guys

I have merged the PRs and cut a release - 0.8.3.

@ianfhunter thanks a lot for the patch! Really appreciate it!
