 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-23.0.3 ------------------------------------------------------
 ---------------------------------------------------------------------

 --- Improvements and New Features ---

  OTP-16711    Application(s): otp

               Update WSL build scripts to work on newer versions.


 ---------------------------------------------------------------------
 --- compiler-7.6.2 --------------------------------------------------
 ---------------------------------------------------------------------

 The compiler-7.6.2 application can be applied independently of other
 applications on a full OTP 23 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-16708    Application(s): compiler
               Related Id(s): ERL-1276

               When calls to is_map_key were repeated, the compiler
               could terminate with an internal consistency failure.


  OTP-16745    Application(s): compiler
               Related Id(s): ERL-1289

               Fixed a bug in the type inference pass that could cause
               the compiler to hang.

 hipe-3.12, kernel-7.0, stdlib-3.13


 ---------------------------------------------------------------------
 --- erts-11.0.3 -----------------------------------------------------
 ---------------------------------------------------------------------

 The erts-11.0.3 application can be applied independently of other
 applications on a full OTP 23 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-16704    Application(s): erts
               Related Id(s): ERL-1273, PR-16704

               Fixed bug in erlang:load_nif/2 that could cause it to
               throw badarg exception if a concurrent code change
               operation was in progress. Bug existed since OTP 23.0.


  OTP-16717    Application(s): erts

               Minor fix of debug compiled VM.


  OTP-16766    Application(s): erts
               Related Id(s): ERL-1304

               An unintentional reuse of an already used emulator
               internal event object could cause a wakeup signal to a
               thread to be lost. In worst case this could cause the
               runtime system to hang. This hang was however quite
               rare.


  OTP-16772    Application(s): erts
               Related Id(s): ERL-1304

               NIF threads and driver threads on non-Linux systems
               leaked internal resources when terminating. On Windows
               these resources were one event per thread. On most
               other systems one mutex and one condition variable per
               thread. On these other systems that also lacked
               pthread_cond_timedwait() also a pipe with its file
               descriptors was leaked.
