+
+               Fix a bug where merging PLT:s could lose info. The bug
+               was introduced in Erlang/OTP 20.0.

+
+               A timer internal bit-field used for storing scheduler
+               id was too small. As a result, VM internal timer data
+               structures could become inconsistent when using 1024
+               schedulers on the system. Note that systems with less
+               than 1024 schedulers are not effected by this bug.
+
+               This bug was introduced in ERTS version 7.0 (OTP 18.0).

+
+  OTP-14554    Application(s): erts
+               Related Id(s): ERL-468, OTP-14356
+
+               Automatic cleanup of a BIF timer, when the owner
+               process terminated, could race with the timeout of the
+               timer. This could cause the VM internal data structures
+               to become inconsistent which very likely caused a VM
+               crash.
+
+               This bug was introduced in ERTS version 9.0 (OTP 20.0).
