Gavin pointed out to me that my script to build the Weld distribution was broken, so I've create Weld 1.0.0 SP1 (Service Pack 1) which remedies this. You can now find Weld's sources and binaries in artifacts/weld and the CDI API source, javadoc and binary in artifacts/cdi. Download it from here.
Today, Red Hat submitted the final draft of JSR-299, which now goes under the moniker CDI (Contexts and Dependency Injection), along with the Reference Implementation and TCK. Check out the spec and Javadoc.
