 --- HIGHLIGHTS ------------------------------------------------------
 ---------------------------------------------------------------------

  OTP-17317    Application(s): stdlib
               Related Id(s): PR-4757

               Most output functions in the io module now print extra
               error information when provided with invalid arguments.
               The functions are: io:format, io:fwrite, io:put_chars,
               io:nl and io:write.


  OTP-17483    Application(s): otp

               The Efficiency Guide has been extended with a chapter
               about maps.


  OTP-17542    Application(s): erts
               Related Id(s): GH-5031, PR-5032

               init:stop() no longer unloads loaded code before
               terminating the runtime system. On systems with slow
               CPUs (such as Raspberry PI Zero), that can
               significantly speed up termination of the runtime
               system.

  OTP-17432    Application(s): otp
               Related Id(s): GH-4862

               In the Reference manual, the shadowing rules for list
               comprehensions have been clarified.


  OTP-17491    Application(s): otp
               Related Id(s): PR-4909

               Fixed configure issue on BSD.


  OTP-17540    Application(s): otp
               Related Id(s): PR-5101

               The guard BIF is_map_key/2 is now included in the list
               of guard BIFs in the Reference Manual.


 --- Improvements and New Features ---

  OTP-17483    Application(s): otp

               *** HIGHLIGHT ***

               The Efficiency Guide has been extended with a chapter
               about maps.


  OTP-17514    Application(s): otp
               Related Id(s): ERIERL-668

               The configure stage now fails if the canonicalized host
               value is equal to the canonicalized build value when
               cross compiling. Previously the configure stage
               succeeded and the cross build continued by overwriting
               the bootstrap build results with cross build results
               which caused failure to build Erlang code.


  OTP-17549    Application(s): otp
               Related Id(s): GH-3533

               A new section about accidental loss of sharing has been
               added to the "Common Caveat" chapter of the Efficiency
               Guide.

  OTP-17522    Application(s): asn1
               Related Id(s): GH-4902

               A parameterized type with a SEQUENCE with extension
               ("...") made the compiler backend to crash. The
               previous fix for this in GH-4514 was not complete.

               Related Id(s): PR-4767

               Float allowed as multiply_timetraps parameter.


  OTP-17632    Application(s): common_test
               Related Id(s): PR-5022

               Remove usage of legacy API macro and functions.

 --- compiler-8.0.3 --------------------------------------------------
 ---------------------------------------------------------------------

 The compiler-8.0.3 application can be applied independently of other
 applications on a full OTP 24 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-17421    Application(s): compiler

               If a parse transform raised an exception using throw/1
               or exit/1, the compiler would report that as an
               internal compiler error, which would be confusing.
               Amended to report that the parse transform failed.


  OTP-17430    Application(s): compiler, stdlib

               The failing call io:format("~p\n") would result in a
               warning for line number 0 instead of the correct line
               and column numbers. This has been corrected, and all
               warnings for failing calls to io:format() has been
               rephrased to make it clearer exactly what the problem
               is.


  OTP-17434    Application(s): compiler, stdlib
               Related Id(s): GH-4772

               When the options warn_missing_spec and export_all were
               given, there would only be warnings for missing specs
               for functions that had been explicitly exported using
               an -export attribute.


  OTP-17446    Application(s): compiler
               Related Id(s): PR-4899

               In rare circumstances, the compiler could emit an
               incorrect warning for a term that was constructed but
               never used.


  OTP-17495    Application(s): compiler, erts
               Related Id(s): PR-5153

               Corrected bugs where builds were not reducible even
               when the deterministic option was given. In particular,
               modules with map literals with more than 32 elements
               could cause this problem.

               As part of this fix, the term_to_binary BIF now accepts
               the option deterministic.


  OTP-17505    Application(s): compiler, stdlib
               Related Id(s): GH-4995

               The MODULE and MODULE_STRING macros would always appear
               to be defined (when tested by -ifdef), even though no
               -module() declaration had been seen yet. Changed so
               that -ifdef ?MODULE. will not consider ?MODULE defined
               if -module() has not been previously seen.


  OTP-17510    Application(s): compiler
               Related Id(s): GH-5007

               In a guard, not (X =:= true) would incorrectly evaluate
               to false for non-boolean values of X.


  OTP-17581    Application(s): compiler, stdlib
               Related Id(s): PR-5141

               When the deterministic option was given to the
               compiler, the ?FILE macro would be expanded to full
               path of the source file before the first include
               directive and to base part of the filename after
               include directive.

               Related Id(s): ERIERL-679

               Fix bug in crypto:ensure_engine_unloaded. Also fixed
               minor memory leak related to engine unloading.


  OTP-17618    Application(s): crypto
               Related Id(s): GH-4920, PR-5126

               Fixes that FIPS enable and disable (or vice versa) on
               Windows sometimes leads to core dump at the time of
               process exit.


 --- Improvements and New Features ---

  OTP-17389    Application(s): crypto

               Disable fips if cryptolib < 1.0.1 and OTP/crypto is
               configured with --enable-fips

               If not, there could be compiling or loading problems
               with antique OpenSSL versions.

               Fixed an error when running as an sftp server and a
               client requests a directory contents listing.

               The fix is to handle the error code {error, eacces} as
               {error, enoent} in the ssh_sftpd:get_attrs/5 internal
               function; that is, just skip it.

               If trying to downgrade a TLS-1.3 connection to a plain
               TCP connection, possible TLS-1.3 session ticket

               waiting for the close notify alert.


  OTP-17521    Application(s): ssl

               insufficient security alert when there are no suitable
               groups that can be negotiated in TLS-1.3 instead of
               crashing resulting in an internal error alert.

               When a client tries to reuse an expired session the
               default server storage handling would crash loosing
               other session data. This would cause a error report and
               possible loss of abbreviated handshakes.
