GNU Guile, a programming and extension language for the GNU Project, is now available as version 3.0.0. According to the team, this is the first release in the stable 3.0 release series.
The major new feature in this version is just-in-time (JIT) native code generation, which helps speed up performance. In this release, microbenchmark performance is twice as good as the 2.2 release, and some individual benchmarks have seen improvements up to 32 times as fast, according to the project maintainers.
Other new features include support for interleaved definitions and expressions in lexical contexts, native support for structured exceptions, and improved support for R6RS and R7RS Scheme standards.
In addition, the team noted that all releases in the 3.0.x series will be parallel-installable with other stable release series, such as 2.2.
