# Changelog v0.3.47 - 2026-04-11

### Fixed
- **jcode model validation freeze** — Fixed terminal freeze when launching jcode with custom models (e.g. GPT OSS 120B via NVIDIA NIM). jcode has a hardcoded model whitelist that rejected non-standard model names passed via `--model` flag, causing the REPL to start without a valid model and hang unresponsively. Now uses `JCODE_MODEL` env var instead, which bypasses the validation and allows any model name to work correctly.
