Dual ES5 and ES2017 Builds
We significantly updated our internal tool and CI setup along the work on PR #913 with an update to ESLint from TSLint for code linting and formatting and the introduction of a new build setup.
Packages now target ES2017 for Node.js builds (the main entrypoint from package.json) and introduce a separate ES5 build distributed along using the browser directive as an entrypoint, see PR #921. This will result in performance benefits for Node.js consumers, see here for a releated discussion.
