Release on NPM

Only core contributors may release to NPM.

To release a new version on NPM, first ensure all tests pass with npm test, then use npm version patch|minor|major in order to increment the version in package.json and tag and commit a release. Then git push && git push --tags to sync this change with source control. Then npm publish npmDist to actually publish the release to NPM. Once published, add release notes. Use semver to determine which version part to increment.

Example for a patch release:

npm test
npm version patch
git push --follow-tags
npm publish npmDist
