+# Changelog
+
+## 0.3.0 - 2026-08-04
+
+Ported to Rust.
+
+- Any executable is a scene (see `docs/procedural.md` for the wire
+  contract).
+- The `ghee-render` wheel carries the embedded renderer and the
+  procedural-scene shim in one package.
+- The deb carries the `ghee` command and the Python package in one, per
+  arch.
+- `docs/http.md`: the console's HTTP API.
+- u8 data arrays.
+- `st7789`: 12-bit colour and partial row updates.
+- The H264 fanout fails fast to the client.
+- `ghee bench`: the benchmark suite, in the binary.
+- `golden --dump` writes the frames out.
