CDI has become one of the key APIs in Java EE since it was first included in Java EE 6. Since then we have seen two minor releases of CDI - CDI 1.1 and CDI 1.2. CDI 2 by comparison promises a significantly larger set of changes and is an opportunity to really push the boundaries for standard dependency injection for Java. To that end the CDI 2 specification has now released an early draft for you to review. An early reference implementation build is also coming soon for you to try out. For now, you should take some time to read through the draft and provide your feedback. CDI 2 specification lead Antoine Sabot-Durand summarized the content of the early draft and outlined the ways you can provide feedback in a well-written blog post. Some of the changes mentioned includes Java SE support, event observer ordering as well as asynchronous events.
Keep in mind this is just the beginning in terms of what the plans for CDI 2 are - there are far more changes on the way. This is your opportunity to chime in and make sure CDI is the high quality standard we all want it to be. You can even choose to do so as a JUG through the Adopt-a-JSR program.
