+- 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
+    exception instead of a badopt error message reply.
