SCUA 0.13.0 is out

July 13, 2026

One week after 0.12.0, this release is about talking to the world. The features have their own posts coming; the short list:

SCUA can now be an HTTP server, behind its own --allow-serve grant. The JIT runs on x86-64 as well as ARM64. wait_all and map_all run many operations at once with no async coloring, and --io=async makes I/O non-blocking under the hood. There is a new regex module built so that no pattern can blow up your CPU, wired into str and fs.grep. UDP datagrams arrived as their own capability. And a family of small additions lands squarely on the AI-tooling side: one-shot tool I/O on sys, JSON Schema emission with scua schema, and b"…" byte-string literals.

Two fixes worth calling out because they were sharp edges: .. on bytes now concatenates bytes instead of producing garbage, and serve verbs called without their grant now name the exact flag to fix it.
