%% ranch_conns_sup is a custom supervisor (special process),
%% not an OTP supervisor. When "supervisor" is used, the
%% module is always loaded before calling system_code_change,
%% for both upgrade and downgrade operations. This is so that
%% the supervisor's init callback of the upgraded/downgraded
%% module gets called. But the custom supervisors in Ranch
%% do not have an init callback and therefore can function
%% like other special processes: when upgrading, load the
%% module then call system_code_change; and when downgrading,
%% call system_code_change and then load the module.
