Release instructions

1. Set the release date in NEWS and merge the pull request for the new release.
2. Build and test the PyPI package on your local machine (see https://packaging.python.org/distributing/ for complete instructions).
   • git clean -dfx
   • Make sure the new release is tagged (git tag x.y.z -m 'Version x.y.z') and that version.py is up to date (run python3 get_version.py) before making the final distribution package.
   • python3 setup.py sdist to create the source distribution.
     • We no longer distribute wheels, because this prevents precompiling the Hy code during installation.
   • Create a new virtualenv and install the created package there for testing:
     • virtualenv tenv -p python3 && cd tenv && source ./bin/activate && pip install fastentrypoints && pip install [source distribution file] && deactivate && source ./bin/activate && echo `type hy` && echo '(+ 1 1)' | hy
3. Publish the release on GitHub.
   • git push --tags origin
   • Add an item to https://github.com/hylang/hy/releases .
4. Fast-forward the stable branch on GitHub.
5. Check that all's well with the documentation: https://readthedocs.org/projects/hy/builds
6. Let @paultag and @Kodiologist know that things are ready. Either of them can upload the package into PyPI.
   • twine upload dist/*
7. Similarly, publish the corresponding new release of Hyrule.
   • Add a commit (only for the new version tag, not master) that sets Hyrule's version number and declares a dependency on the Hy release in setup.py.
8. Use the new releases of Hy and Hyrule for the web console.
