v2.2.0

What's New in v2.2.0

Runtime status reporting

• Added a JSON runtime status file for health monitoring.
• Tracks startup time, latest public IP, latest IP check, per-domain state, recent errors, and shutdown state.
• Added STATUS_FILE_PATH, defaulting to status/flaresync-status.json.

Graceful shutdown

• Added SIGINT and SIGTERM handling.
• Shutdown can now interrupt IP discovery, Cloudflare updates, retry sleeps, and interval waits.
• FlareSync writes a final status update before exiting.

Reliability and security hardening

• Status writes now use a temporary file and atomic rename to avoid partial JSON reads.
• Cloudflare API error handling now preserves API error details and classifies transient errors more safely.
• DNS backup filenames now include sub-second timestamps and are created with safer file permissions.
• Switched HTTP TLS handling to rustls.

Docker updates

• Docker image now explicitly runs as the distroless nonroot user.
• Docker copy steps preserve nonroot ownership.
• Docker examples now mount ./status:/app/status.
• Build image and cargo-chef install behavior were updated to avoid brittle pinned image/tooling behavior.

Maintenance

• Bumped package version to 2.2.0.
• Updated dependencies and lockfile.
• Added focused regression coverage for status writing, config defaults, Cloudflare response parsing, and backup permissions.
