- Changes for 23.1.3:
* erts: Fixed a crash when exceptions were thrown during call
time tracing.
* ssh: A supervisor sub-tree could be left if the connection
handler process is brutally killed. This will make the
max_sessions checking option to count the existing sessions
erroneously and could finally block further sessions.
- Changes for 23.1.2:
* compiler: Fixed a bug in the boolean optimization pass that
caused the compiler to confuse different clauses.
* erts: Fixed bugs causing issues when enabling the ERTS internal
allocators on a system built with the undocumented and
unsupported SMALL_MEMORY feature.
* erts: The inet driver used to use 16 as maximum elements in an
I/O vector passed to writev() (and WSASend() on Windows). When
the data to send contained lots of elements, this caused a
performance degradation since repeated calls to writev() had to
be made to a much larger extent. The inet driver now looks up
actual maximum amount of elements that can be used on the
system, instead of just assuming 16. On most systems this will
result in a maximum amount of I/O vector elements of 1024. As
of OTP 23.0 the term encoding of signals to send over the
distribution are encoded into I/O vectors of buffers instead of
into a single buffer. Reference counted binaries are referred
to directly from the I/O vector instead of being copied into
the single buffer. That is, Erlang signals containing huge
amounts of reference counted binaries was effected by this
performance degradation.
* erts: In the distributed case, a faulty reply option in a call
to the spawn_request() BIF erroneously caused a badarg
