v3.1.0

This release introduces GitHub Container Registry (GHCR) support as the primary container distribution method, while maintaining backward compatibility with Docker Hub. This strategic shift ensures better integration with GitHub's ecosystem and improved reliability for container deployments.

Important: Docker Hub support will be discontinued on February 28, 2026. Please migrate to GitHub Container Registry before this date.

Update Procedure

Please follow this process:

For Docker Hub users (current method):

docker compose pull

docker compose up -d

For GitHub Container Registry users (mandatory):

1. Update your docker-compose.yml to use the new GHCR image:

services:
  watcher:
    image: ghcr.io/thalesgroup-cert/watcher:latest
    # ...rest of configuration

1. Pull and restart:

docker compose pull
docker compose down
docker compose up -d
