Developing package releases

The commits on the development branch of each version will be packaged and uploaded to Test PyPI.

The package name generated by the development branch is x.y.z.rc<dist>, where <dist> is the number of commits that differ from the most recent release.

To install the package on Test PyPi, you need to append --extra-index-url after pip, for example:

$ python3 -m pip install --extra-index-url https://test.pypi.org/simple/ pymilvus==2.1.0.dev66
