Erlang/OTP 21.2.4

Note! The erts-10.2.3 application can *not* be applied independently of other applications on an arbitrary OTP 21 installation. On a full OTP 21 installation, also the following runtime dependencies have to be satisfied: -- kernel-6.1 (first satisfied in OTP 21.1) -- sasl-3.3 (first satisfied in OTP 21.2)
