 * `OSTREE_COMMIT_SUBJECT` - Commit subject used by OSTree. Defaults to `Commit-id: ${IMAGE_NAME}`
 * `OSTREE_UPDATE_SUMMARY` - Set this to '1' to update summary of OSTree repository on each commit. '0' by default.
 * `OSTREE_DEPLOY_DEVICETREE` - Set this to '1' to include devicetree(s) to boot
+* `GARAGE_SIGN_AUTOVERSION` - Set this to '1' to automatically fetch the last version of the garage tools installed by the aktualizr-native. Otherwise use the fixed version specified in the recipe.
 * `INITRAMFS_IMAGE` - initramfs/initrd image that is used as a proxy while booting into OSTree deployment. Do not change this setting unless you are sure that your initramfs can serve as such a proxy.
 * `SOTA_PACKED_CREDENTIALS` - when set, your ostree commit will be pushed to a remote repo as a bitbake step. This should be the path to a zipped credentials file in https://github.com/advancedtelematic/aktualizr/blob/master/docs/credentials.adoc[the format accepted by garage-push].
 * `SOTA_DEPLOY_CREDENTIALS` - when set to '1' (default value), deploys credentials to the built image. Override it in `local.conf` to built a generic image that can be provisioned manually after the build.
