Loko Scheme 0.13.0 landed on scheme.fail today, offering a fresh tarball and a signed bootable disk image for 64‑bit PCs. The release includes a Gnu PG signature verified with key 0xDD839B748F10AD4D, ensuring integrity for developers pulling the binaries. The compiler continues to target bare metal, Linux and NetBSD/amd64 platforms. Developers can also download the image directly via HTTP or use torrent mirrors for faster transfer.

Version 0.13.0 patches numerous bugs, trims compilation latency and adds several language extensions. It remains compliant with R6RS and R7RS standards, letting code run unchanged across Scheme ecosystems. The NEWS.md file enumerates the changes, while the manual on the site details the new optimization flags that reduce binary size on constrained hardware. Performance tests show up to a 12% speed gain on typical benchmark suites.

The project is distributed under the EUPL v1.2 license and hosted on scheme.fail, which also provides a mailing list for community support. By delivering statically linked binaries, Loko Scheme simplifies deployment in containerized or embedded environments, a niche where traditional interpreters struggle. Users can verify the release signatures before integrating the compiler into their build pipelines. The verification runs via Makefile, cutting manual effort.
