+ Check out the git tag OTP-23.1.2, and build a full OTP system
+ including documentation. Apply one or more applications from this
+ build as patches to your installation using the 'otp_patch_apply'
+ tool. For information on install requirements, see descriptions for
+ each application version below.

+  OTP-16951    Application(s): compiler
+               Related Id(s): ERL-1384
+
+               Fixed a bug in the boolean optimization pass that
+               caused the compiler to confuse different clauses.

+
+  OTP-16939    Application(s): erts
+
+               Fixed bugs causing issues when enabling the ERTS
+               internal allocators on a system built with the
+               undocumented and unsupported SMALL_MEMORY feature.

+
+               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.
+
+
+  OTP-16991    Application(s): erts
+               Related Id(s): OTP-15251
+
+               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.
