-	$ export MINOR_RELEASE=0.12
-
-	$ docker pull --platform linux/amd64 gogs/gogs:${VERSION}
-	$ docker tag gogs/gogs:${VERSION} gogs/gogs:${MINOR_RELEASE}-amd64
-	$ docker push gogs/gogs:${MINOR_RELEASE}-amd64
-	$ docker pull --platform linux/arm64 gogs/gogs:${VERSION}
-	$ docker tag gogs/gogs:${VERSION} gogs/gogs:${MINOR_RELEASE}-arm64
-	$ docker push gogs/gogs:${MINOR_RELEASE}-arm64
