Workflow for new Flink releases
-------------------------------
-### Note for new Flink minor (x.y.0) releases
+### Notes for new Flink minor (x.y.0) releases
-When a new Flink minor version (x.y.0) is released, the `aliases` array in
-`generate-stackbrew-library.sh` must be updated so that the images for the new release are tagged
-`latest`.
+There are additional steps required when a new Flink minor version (x.y.0) is released.
+
+* Since only the current and previous minor versions of Flink are supported, the Dockerfiles for
+ older versions must be removed when adding the new version to this repo
+* The new images should be given the `latest` tag, so the `aliases` array in
+ `generate-stackbrew-library.sh` must be updated
