cc @jackye1995 , marked the PR as ready for review

[jackye1995]

Any update on this?

[jackye1995]

Looks good to me, pending CI passing. Also the current description seems empty, we should describe the breaking change.

[yanghua]

Traceback (most recent call last):
New version: (0, 30, 1)
Last version: (0, 30, 0)
No breaking changes found.
  File "/home/runner/work/lance/lance/pr/../base/ci/check_versions.py", line 77, in <module>
    new_version[1] == last_version[1] + 1
AssertionError: Minor version should have been bumped because there was a breaking change.
Error: Process completed with exit code 1.

@jackye1995 The breaking change policy failed. Shall we update the version? Or just ignore?

[jackye1995]

Yeah if you are the first author to do breaking change after the last release, then you need to do the version bump
