 # Changelog
 
+## 0.14.20
+
+- Fixes ARM cross-build startup by removing the invalid `xx-cargo --version` probe; `xx-cargo build` remains the cross-compilation entry point.
+- Installs the Rust target standard library in a cacheable layer before project sources are copied, so source-only changes do not redownload/reinstall it.
+- Fetches Cargo dependencies before target-specific setup so amd64/arm64 reuse the same registry/git cache.
+- Separates compiled `target/` caches by target architecture to avoid multi-platform build contention while retaining incremental dependency reuse.
+- Keeps the existing `build.sh` workflow and `DISTRO=alpine` (musl/Alpine) versus `DISTRO=trixie` (GNU/glibc Debian Trixie) runtime selection unchanged.
+
 ## 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.
