v1.1 — 2026-08-28

Raised the maximum run memory to 2 GB so memory-heavy snippets can be given more room (default run stays at 512 MB)
Documented how the JavaScript heap and Python address-space limits scale with the run's memory

v1.0 — 2026-08-28

Initial release
Run JavaScript (Node.js 22) or Python 3 snippets, up to 100 KB of source
Send data to the snippet through standard input as a JSON value or a raw string
Capture a byte-capped combination of standard output and standard error
Optional parsing of standard output into a JSON result field
Configurable wall-clock timeout from 1 to 30 seconds, enforced on the whole process group
Preserve up to 10 generated files to the run's key-value store, with a combined size cap
One structured execution record per run — status, exitCode, signal, durationMs, timedOut, outputTruncated, terminationReason, result, files, and more
Snippets run under a dedicated unprivileged user with no_new_privs, a minimal environment, and CPU, file-descriptor, and process limits
