I am a bit confused by there being erlang-runtime ports for versions 20 and 21, but the main erlang lang port is at version 19.3. Presumably version 19.3 cannot be used to develop stuff which runs on 21? If not, what is the rationale for the existence of the later runtimes? Thanks for your help John
