As you know, CDI 1.1 is an important part of Java EE 7. You may be happy to know that the CDI specification just releases another minor point release - 1.2. As you can imagine the release contains a small number of fixes and clarifications. If you are surprised that a technology that is part of the Java EE platform had an independent release, you really shouldn't be. Although for various practical reasons Java EE technologies are usually synchronized with the platform JSR, individual JSRs are completely free to follow their own release schedule. Past examples include JSF and JAX-RS (and quite possibly JCache now).
The detailed list of changes are outlined on the CDI specification site.
