v1.4.0

Added

• Per-image version overrides. Every pin in the x-images block is
  now ${<PREFIX>_IMAGE_TAG:-repo:${<PREFIX>_IMAGE_VERSION:-tag@sha256:digest}}.
  Set <PREFIX>_IMAGE_VERSION in .env to run a different version of one
  image while every other pin stays as tested (Compose pulls that tag
  without a digest), or <PREFIX>_IMAGE_TAG to replace the whole
  reference as before. A deployment that sets neither is unchanged. The
  freshness job, the Trivy matrix and the fleet digest automation resolve
  the nested default before reading a pin. Needs Docker Compose v2.5 or
  newer (2022): v2.0 to v2.4 leave the inner ${...} unexpanded and
  docker compose up fails with an invalid reference instead of
  deploying something unexpected.

Changed

• itzg/mc-proxy 2026.8.2 to 2026.9.0.

Upgrading

git pull (or ./update.sh). A deployment that sets no _IMAGE_VERSION or _IMAGE_TAG variable renders exactly the same image references as before, so docker compose up -d recreates nothing. Requires Docker Compose v2.5 or newer.
