Making a new release

This project uses semantic versioning and tags releases with X.Y.Z Every time a new tag is created and pushed to the remote repo, github actions will automatically create a new release on github and trigger a release on PyPI.

For this to work you need to setup a secret called PIPY_API_TOKEN on the project settings>secrets, this token can be generated on pypi.org.

To trigger a new release all you need to do is.

  1. If you have changes to add to the repo
  2. Run the tests to ensure everything is working.
  3. Run make release to create a new tag and push it to the remote repo.

the make release will ask you the version number to create the tag, ex: type 0.1.1 when you are asked.

CAUTION: The make release will change local changelog files and commit all the unstaged changes you have.
