  OTP-15225    Application(s): erts

               Fixed a bug causing some Erlang references to be
               inconsistently ordered. This could for example cause
               failure to look up certain elements with references as
               keys in search data structures. This bug was introduced
               in R13B02.

               Thanks to Simon Cornish for finding the bug and
               supplying a fix.

 --- compiler-7.2.3 --------------------------------------------------
 ---------------------------------------------------------------------

 The compiler-7.2.3 application can be applied independently of other
 applications on a full OTP 21 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-15204    Application(s): compiler
               Related Id(s): ERL-679

               Fixed an issue where files compiled with the
               +deterministic option differed if they were compiled in
               a different directory but were otherwise identical.

 --- crypto-4.3.1 ----------------------------------------------------
 ---------------------------------------------------------------------

 The crypto-4.3.1 application can be applied independently of other
 applications on a full OTP 21 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-15194    Application(s): crypto
               Related Id(s): ERL-673

               Fixed a node crash in crypto:compute_key(ecdh, ...)
               when passing a wrongly typed Others argument.

 ---------------------------------------------------------------------
 --- erts-10.0.5 -----------------------------------------------------
 ---------------------------------------------------------------------

 The erts-10.0.5 application can be applied independently of other
 applications on a full OTP 21 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-15223    Application(s): erts

               Fixed a bug which caused an emulator crash when
               enif_send() was called by a NIF that executed on a
               dirty scheduler. The bug was either triggered when the
               NIF called enif_send() without a message environment,
               or when the process executing the NIF was send traced.
