 - Release-Refs/Tarballs: Tags/Commits unter `https://git.taler.net/{gnunet,exchange,merchant,libeufin}.git/` ansehen (Tarballs via `.../snapshot/<tag>.tar.gz`) und `*_REF`/`GNUNET_TARBALL_URL` entsprechend setzen.
 - Offline-Tarballs: Lege Tarballs unter `vendor/` ab (`gnunet-*.tar.gz`, `exchange-*.tar.gz`, `merchant-*.tar.gz`, `libeufin-*.tar.gz`); bei unvollständigem Tarball fällt der Build auf Git zurück.
+- Release-Tarballs laden: `./scripts/fetch-tarballs.sh` (nutzt aktuelle Stable-Versionen; per `*_VERSION` oder `*_TARBALL_URL` überschreibbar).
 
 ## Nützliche Kommandos
 - Logs: `docker compose logs -f exchange` (oder bank/merchant/caddy/wordpress).

 - After changing DB passwords in `.env`, no manual SQL rendering is needed—the init script reads them at container start.
 - Release refs/tarballs: Browse tags/commits at `https://git.taler.net/{gnunet,exchange,merchant,libeufin}.git/` (Tarballs via `.../snapshot/<tag>.tar.gz`) and set `*_REF`/`GNUNET_TARBALL_URL` accordingly.
 - Offline tarball drop-in: place tarballs under `vendor/` (`gnunet-*.tar.gz`, `exchange-*.tar.gz`, `merchant-*.tar.gz`, `libeufin-*.tar.gz`); the build picks the first match and falls back to git if incomplete.
