+* Removed Makefile (Had switched to Gulp, but removed that as well); Using the _scripts_ field of `package.json` instead
 * Rewrote `tools/impact` (a bash script, dependent on external tools) as `test/impact` (a cross-platform Node script)
 * Added code coverage ([Istanbul](https://www.npmjs.com/package/nyc) and [coveralls.io](https://coveralls.io/github/pegjs/pegjs))
