The release version number of PyMilvus follows PEP440, the format is x.y.z, and the corresponding git tag name is vx.y.z (x/y/z are numbers from 0 to 9).

For example, after PyMilvus 1.0.1 is released, a tag named v1.0.1 can be found on GitHub, and a package with version 1.0.1 can be downloaded on PyPI.

Developing packages

The commits on the development branch of each version will be packaged and uploaded to Test PyPI. Development branches refer to branches such as 1.0 and 1.1, and version releases are generated from the development branches, such as 1.0.1 and 1.0.2.
