June 2026: CI Build Reliability improvements for containerd/containerd. Stabilized the Go toolchain by pinning the setup-go action to a specific hash and removing an outdated cache-disable setting, increasing CI build stability and determinism. Commit: 80b3fe5c78b93b56b496cdd10b15f2c0ee6d5bb9.

January 2026: Built and documented a modernization of the containerd build workflow by transitioning protobuf compilation to buf, with removal of the protoc dependency from BUILDING.md. This aligns the repository with a standardized, maintainable code-generation path and reduces external build-time dependencies. Commit 19f39fee6f40889e8072fdeec9fefc2887eff432 captured the change and serves as the reference for the buf-based workflow.
