- Update to 20.0.4:
* dializer: Fix a bug where merging PLT:s could lose info. The
bug was introduced in Erlang/OTP 20.0.
* erts: 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).
* erts: 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).
- Update to 20.0.3:
* asn1: Default values now work in extension for PER, so if you
give the atom asn1_DEFAULT instead of a value it will become
the default value.
* compiler: Fail labels on guard BIFs weren't taken into account
during an optimization pass, and a bug in the validation pass
sometimes prevented this from being noticed when a fault
occurred.
* erts: Binary append operations did not check for overflow,
resulting in nonsensical results when huge binaries were
appended.
* ssh: All unknown options are sent to the transport handler
regardless of type.
