# Changelog

## 0.2.2 — 2026-10-22

- Add separate official release archives for Linux AArch64 (GNU/glibc) and native Android/Termux AArch64 (Bionic), with binary ABI checks and SHA-256 sums for all downloads.
- Continue packaging native Linux x86_64, macOS Apple Silicon and Windows x86_64 binaries and reproducible tagged source snapshots.
- No changes to the reviewed v0.2.1 single-file Unix \`--resume\` runtime. Windows single-file resume remains unsupported.
- Multi-file \`--resume-dir\` is **not** part of this release: its active-adversary and power-loss security review is incomplete, so it is excluded from the stable binaries and source archives.
- Packaged programs are not code-signed or notarized; validate hashes and use only on supported platforms.

## 0.2.1 — 2026-10-21

- Enforce no-overwrite at commit time on Linux/Android with RENAME_NOREPLACE, and otherwise safe no-replace hard-link publication.

## Install

Requires the Rust toolchain with Cargo.
Version 0.2.2 adds separate downloadable Linux AArch64 and native Android/Termux AArch64 binaries alongside Linux x86_64, Windows x86_64 and macOS Apple Silicon. See the [GitHub Releases](https://github.com/Olize/mch/releases) page for the package matching your architecture and verify it against \`SHA256SUMS.txt\` before use. **Linux AArch64 (glibc) is not a Termux binary**; Android/Termux requires the \`android-aarch64-termux\` archive with the Android Bionic linker.

To build from source instead, the Rust toolchain with Cargo is required.

```bash
git clone https://github.com/Olize/mch.git
