 For the Home Assistant package, TCP `8787` is an intentional fixed host-network/ingress port contract. `build.sh render` verifies `config.yaml`, `run.sh`, the watchdog URL and Docker image metadata stay consistent. The runtime also compares the Supervisor-reported ingress port before starting. Standalone installations remain free to use any `GREE_CONTROLLER_BIND` port.
 
+`DISTRO` still selects the target image system: `alpine` builds a musl binary for Alpine and `trixie` builds a GNU/glibc binary for Debian Trixie. Multi-architecture builds continue to run through `build.sh`; the Docker builder cross-compiles Rust on `BUILDPLATFORM` so ARM compilation does not run under QEMU, and BuildKit cache mounts preserve Cargo downloads and target artifacts between builds.

 # Changelog
 
+## 0.14.19
+
+- Speeds up multi-architecture OCI builds by running Rust/Cargo on `BUILDPLATFORM` and cross-compiling to amd64/arm64 instead of compiling ARM under QEMU.
+- Keeps `DISTRO=alpine` as a musl/Alpine target and `DISTRO=trixie` as a GNU/glibc Debian Trixie target; `build.sh` remains the build entry point.
+- Adds persistent BuildKit caches for Cargo registry/git data and compiled target artifacts; target Rust/C toolchains are prepared before project manifests so normal version/source changes keep the cross-toolchain layer cached.
+- Reduces Docker build context and avoids invalidating Rust compilation for unrelated documentation/repository changes; only `docs/openapi.json` is copied because it is embedded by the binary.
+- Deduplicates `/api/integrations/gree-cloud/status` across the initial HTTP bootstrap and immediate WebSocket bootstrap render while keeping manual Cloud reconnect refreshes forced.
+
 ## 0.14.18
 
 - Renames the shared segmented navigation class from feature-specific `automation-tabs` to generic `segmented-tabs`.
