 ---------------------------------------------------------------------
 --- OTP-23.1.1 ------------------------------------------------------
 ---------------------------------------------------------------------

 --- Fixed Bugs and Malfunctions ---

  OTP-16903    Application(s): otp
               Related Id(s): ERL-1362

               Fixed the missing redistribution file in the windows
               installers.


 ---------------------------------------------------------------------
 --- compiler-7.6.4 --------------------------------------------------
 ---------------------------------------------------------------------

 The compiler-7.6.4 application can be applied independently of other
 applications on a full OTP 23 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-16895    Application(s): compiler
               Related Id(s): ERL-1359

               Fixed a performance bug that could be triggered by
               tuple matching in very large functions.


 Full runtime dependencies of compiler-7.6.4: crypto-3.6, erts-11.0,
 hipe-3.12, kernel-7.0, stdlib-3.13


 ---------------------------------------------------------------------
 --- erts-11.1.1 -----------------------------------------------------
 ---------------------------------------------------------------------

 The erts-11.1.1 application can be applied independently of other
 applications on a full OTP 23 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-16847    Application(s): erts
               Related Id(s): ERL-1301

               inet:setopts([{active,once}]) wakes up IO polling
               thread unnecessarily, leading to lock contention and
               visibly higher CPU utilization.


  OTP-16870    Application(s): erts

               Two bugs in the ERTS internal thread wakeup
               functionality have been fixed. These bugs mainly hit
               when all threads in the system tried to go to sleep.
               When the bugs were triggered, certain operations were
               delayed until a thread woke up due to some other
               reason. Most important operations effected were code
               loading, persistent term updates, and memory
               deallocation.


  OTP-16874    Application(s): erts
               Related Id(s): ERL-1356, PR-2763

               Fixed bug in ets:select_replace/2 on compressed tables
               that could produce faulty results or VM crash. Bug
               exists since OTP 20.


  OTP-16892    Application(s): erts

               When compiling Erlang/OTP on macOS using Xcode 12, the
               performance of the BEAM interpreter would be degraded.


 --- Improvements and New Features ---

  OTP-16856    Application(s): erts

               As of OTP 22, the allocator specific memory carrier
               pools were replaced by a node global carrier pool. This
               unfortunately caused substantial memory fragmentation
               in some cases due to long lived data being spread into
               carriers used by allocators mainly handling short lived
               data.

               A new command line argument +M<S>cp has been introduced
               with which one can enable the old behavior as well as
               configuring other behaviors for the carrier pools. In
               order to configure the old behavior, with allocator
               specific carrier pools for all allocators, pass +Mucp :
               (including the colon character) as a command line
               argument to erl when starting the Erlang system.

               The default configuration for carrier pools will be
               changed to +Mucp : some time in the future, but not in
               this patch.

 ---------------------------------------------------------------------
 --- os_mon-2.6.1 ----------------------------------------------------
 ---------------------------------------------------------------------

 The os_mon-2.6.1 application can be applied independently of other
 applications on a full OTP 23 installation.

 --- Improvements and New Features ---

  OTP-16906    Application(s): os_mon
               Related Id(s): ERIERL-532

               The configuration parameter
               memsup_improved_system_memory_data has been introduced.
               It can be used to modify the result returned by
               memsup:get_system_memory_data(). For more information
               see the memsup documentation.

               Note that the configuration parameter is intended to be
               removed in OTP 24 and the modified result is intended
               to be used as of OTP 24.

 ---------------------------------------------------------------------
 --- public_key-1.9.1 ------------------------------------------------
 ---------------------------------------------------------------------

 The public_key-1.9.1 application can be applied independently of
 other applications on a full OTP 23 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-16902    Application(s): public_key
               Related Id(s): ERIERL-534

               Fix the issue that pem_decode will crash with an
               invalid input.

 applications on a full OTP 23 installation.

 --- Fixed Bugs and Malfunctions ---

               Fix decoder bug.
