Dear Spring Community,

We are pleased to announce the release of when.js 2.0.0.

When.js is cujojs’s lightweight Promises/A+ and when() implementation, and powers the async core of wire.js, cujojs’s IOC Container. It also provides several other useful Promise-related concepts, such as joining multiple promises, mapping and reducing collections of promises, and timed promises.

This major release brings full Promises/A+ compliance, and async promise resolutions. It also includes a few new features, including a new when/keys module for working with object keys.

See the cujojs discussion group for further detail, and check out the full changelog for more info and direct links to docs for the new features.
