 --- compiler-7.2.2 --------------------------------------------------
 ---------------------------------------------------------------------

 The compiler-7.2.2 application can be applied independently of other
 applications on a full OTP 21 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-15156    Application(s): compiler
               Related Id(s): ERL-655

               In rare cases involving matching of binary literal
               strings, the compiler could optimize away code that
               should be executed.


  OTP-15157    Application(s): compiler

               There could be an internal consistency check failure
               when compiling code that called map_get(Key, Map) and
               then updated the same map.


  OTP-15166    Application(s): compiler
               Related Id(s): ERL-660

               In rare circumstances, the compiler could crash in
               beam_jump when compiling a floating point operation.


 Full runtime dependencies of compiler-7.2.2: crypto-3.6, erts-9.0,
 hipe-3.12, kernel-4.0, stdlib-2.5


 ---------------------------------------------------------------------
 --- erts-10.0.2 -----------------------------------------------------
 ---------------------------------------------------------------------

 The erts-10.0.2 application can be applied independently of other
 applications on a full OTP 21 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-15067    Application(s): erts
               Related Id(s): ERL-573

               Fixed a rare bug that could cause processes to be
               scheduled after they had been freed.


  OTP-15158    Application(s): erts
               Related Id(s): ERL-654

               Fixed a race condition in the inet driver that could
               cause receive to hang when the emulator was compiled
               with gcc 8.


 Full runtime dependencies of erts-10.0.2: kernel-6.0, sasl-3.0.1,
 stdlib-3.5


 ---------------------------------------------------------------------
 --- public_key-1.6.1 ------------------------------------------------
 ---------------------------------------------------------------------

 The public_key-1.6.1 application can be applied independently of
 other applications on a full OTP 21 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-15151    Application(s): public_key
               Related Id(s): OTP-15113

               Some of the keylengths in the newly generated moduli
               file in public_key are not universally supported. This
               could cause the SSH key exchange
               diffie-hellman-group-exchange-sha* to fail.

               Those keylengths are now removed.


 Full runtime dependencies of public_key-1.6.1: asn1-3.0, crypto-3.8,
 erts-6.0, kernel-3.0, stdlib-3.5


 ---------------------------------------------------------------------
 --- stdlib-3.5.1 ----------------------------------------------------
 ---------------------------------------------------------------------

 The stdlib-3.5.1 application can be applied independently of other
 applications on a full OTP 21 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-15159    Application(s): stdlib

               Fix a bug that could cause a crash when formatting a
               list of non-characters using the control sequences p or
               P and limiting the output with the option chars_limit.


 Full runtime dependencies of stdlib-3.5.1: compiler-5.0, crypto-3.3,
