 Note! The erts- application *cannot* be applied
       independently of other applications on an arbitrary OTP 21

       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)

               has not been verified. Match specs are used by
               ets:match/select functions and erlang:trace_pattern.

               calling process had incoming signals at the time of the
               call. This bug was introduced in OTP 23.3.2 (ERTS
               version 11.2.1), OTP (ERTS version
