Numba 0.54.1 bugfix release RC1

Hi all,

We are releasing Numba 0.54.1rc1, a release candidate for our upcoming bugfix release which will contain multiple patches for the reported regressions.

@RC_Testers, I want to draw your attention to the patch for the serialization issue for dynamic classes (PR#7388). The patch contains a change to the vendored cloudpickle. Users who rely on serialization and caching extensively will want to verify if the deviating cloudpickle behavior has an unexpected impact to your projects.

For details, please refer to the release notes.

Conda packages can be installed from the numba channel on with conda :

conda install -c numba numba=0.54.1rc1

@sklam I tested Numba 0.54.1rc1 on Bodo and all tests pass. I checked a sample benchmark to see if caching/compilation time would be impacted and I didn’t notice any significant differences.

Can report tests pass for our internal libraries.
