We are pleased to announce GNU Guile 2.0.3, the third maintenance release of the 2.0.x stable series.
The main highlight of this release is the compiler's new optimizer, based on a partial evaluator. It provides the usual optimizations: procedure inlining, copy propagation, and constant folding. The new REPL `,optimize' command allows users to see how it would optimize a given expression.
The release also comes with a few new features and many bug fixes.
