name: release

# On a version tag this builds the package once, publishes it to PyPI via
# trusted publishing (no API token stored in the repo), and attaches the built
# wheel and sdist to a GitHub Release for the tag. The PyPI project must list
# this repo and workflow as a trusted publisher first.

  push:
    # PyGAD tags releases as the bare version number, e.g. 3.6.0 (no "v").
