It seems good to point out a change that may surprise people that have scripts that depend on the old process name "beam.smp" which now changes to the script name, or is set by an environment variable:

   OTP-14381    Application(s): erts

                Changed erts startup program name, argv 0, to use the
                environment variable ESCRIPT_NAME so that erlc,
                dialyzer, typer, ct_run, or the escript name can be
                seen with external programs, such as ps and htop
                (depending on options), on unix.

                If environment variable ESCRIPT_NAME is not set, argv 0
                of the invoking program will be used, e.g. the name
                will be erl, cerl, or the soft link name.

This is a great change, but one to be aware of.

Best Regards,
