Good point. Currently we don't specify a revision in the bundle, so it uses the one in the stable channel. Explicitly providing the revision would fix the issue of release testing. However, wouldn't it cause a problem for development testing (i.e. "make stage-landscape-charm && make -C build/landscape-charm deploy-dense-maas")?
