SharePoint Framework Developer Preview Just Released

In May 2016, Microsoft unveiled a new SharePoint Framework for creating responsive, modular presentation components as a replacement for web parts, app parts, etc.  The framework will be initially released to a new portal experience in Office 365 – I would expect it to be released for SharePoint 2016 on premise as well at some point in the future.
