v0.1.0 — Initial Release

Docker image update notifier with ntfy alerts. Checks running containers against upstream registries and notifies when newer images are available.

Features

• Checks running containers against Docker Hub, ghcr.io, Codeberg, and any OCI-compliant registry
• Anonymous token auth for public images with WWW-Authenticate fallback
• Configurable check interval (default 6h) and per-image notification cooldown (default 24h)
• Glob-based image filtering
• Notify-only — never auto-updates (unlike Watchtower)
• Zero dependencies — pure Python stdlib
• Single-file, lightweight Docker container
