(Huge) changelog from the latest stable Node version v0.10.35, including all changes from unstable v0.11: https://github.com/iojs/io.js/blob/v1.x/CHANGELOG.md

Also of interest, the state of ES6 in io.js: https://github.com/seegno/io.js/wiki/The-state-of-ES6-on-io..... Highlights: 'let', generators, promises, template literals, symbols are all enabled by default. EDIT: just realized this wiki page has been updated and integrated into the website at https://iojs.org/es6.html
