Making a Release

Run towncrier --version=$newversion --draft and check that the output looks OK. Then run it without --draft, deleting the old newsfiles. Commit.
Update the version in package.json, commit, and tag with v$newversion
Push to release the JS version -- git push && git push --tags
Release to PyPi:
- python setup.py sdist
- twine upload dist/json-e-<version>.tar.gz
Go doesn't believe in versions, so there's notihng to do for a Go release!
