Back in May, Microsoft announced their decision to openly share their platform roadmap viastatus.modern.ie. Yesterday, IE team announced another round of updates to their plan. These updates include new ECMAScript, Networking, Performance, Media, CSS, and DOM features under consideration and in development.
Additionally, IE feature statuses are also integrated into caniuse.com via our open data feed. You can also help us make this a valuable resource for developers by contributing to the open source project. As always, ask us questions and give us feedback via @iedevchat.
