We have released version 0.9.1 of the JSR 308 specification and
implementation and of the Checker Framework.  You can always review
the latest version of the specification at: http://groups.csail.mit.edu/pag/jsr308/specification/java-annotation-design.html
; and download the latest version of these tools at:http://groups.csail.mit.edu/pag/jsr308/

The JSR 308 implementation is a backward-compatible extension to
javac. The Checker Framework makes it easy to write a tool that finds
or prevents errors; the tool is expressed as a type-checker for a
pluggable type system.  The Checker Framework distribution includes
sample checkers.

This release includes many bug fixes, mainly related to parsing  
annotations in array levels, unexpected compiler javac errors, and not  
reading annotations in skeleton files.  Also, the release includes  
some API changes (detailed below) that ease using the platform.

The changlogs of the specification and the implementations appear below.
