<p>This document describes the changes made to the Kernel application.</p>
+<section><title>Kernel 5.3</title>
+
+ <section><title>Fixed Bugs and Malfunctions</title>
+ <list>
+ <item>
+ <p>Function <c>inet:ntoa/1</c> has been fixed to return
+ lowercase letters according to RFC 5935 that has been
+ approved after this function was written. Previously
+ uppercase letters were returned so this may be a
+ backwards incompatible change depending on how the
+ returned address string is used.</p>
+ <p>Function <c>inet:parse_address/1</c> has been fixed to
+ accept %-suffixes on scoped addresses. The addresses does
+ not work yet, but gives no parse errors.</p>
+ <p>
+ *** POTENTIAL INCOMPATIBILITY ***</p>
+ <p>
+ Own Id: OTP-13006 Aux Id: ERIERL-20, ERL-429 </p>
+ </item>
+ <item>
+ <p>
+ Fix bug where gethostname would incorrectly fail with
+ enametoolong on Linux.</p>
+ <p>
+ Own Id: OTP-14310</p>
+ </item>
+ <item>
+ <p>
+ Fix bug causing <c>code:is_module_native</c> to falsely
+ return true when <c>local</c> call trace is enabled for
+ the module.</p>
+ <p>
+ Own Id: OTP-14390</p>
+ </item>
+ <item>
+ <p>
+ Add early reject of invalid node names from distributed
+ nodes.</p>
+ <p>
+ Own Id: OTP-14426</p>
+ </item>
+ </list>
+ </section>
+
+
+ <section><title>Improvements and New Features</title>
+ <list>
+ <item>
+ <p>
+ Since Unicode is now allowed in atoms an extra check is
+ needed for node names, which are restricted to Latin-1.</p>
+ <p>
+ Own Id: OTP-13805</p>
+ </item>
+ <item>
+ <p>Replaced usage of deprecated symbolic <seealso
+ marker="erts:erlang#type-time_unit"><c>time
+ unit</c></seealso> representations.</p>
+ <p>
+ Own Id: OTP-13831 Aux Id: OTP-13735 </p>
+ </item>
+ <item>
+ <p><c>file:write_file(Name, Data, [raw])</c> would turn
+ <c>Data</c> into a single binary before writing. This
+ meant it could not take advantage of the <c>writev()</c>
+ system call if it was given a list of binaries and told
+ to write with <c>raw</c> mode.</p>
+ <p>
+ Own Id: OTP-13909</p>
+ </item>
+ <item>
+ <p>The performance of the <c>disk_log</c> has been
+ somewhat improved in some corner cases (big items), and
+ the documentation has been clarified. </p>
+ <p>
+ Own Id: OTP-14057 Aux Id: PR-1245 </p>
+ </item>
+ <item>
+ <p>Functions for detecting changed code has been added.
+ <c>code:modified_modules/0</c> returns all currently
+ loaded modules that have changed on disk.
+ <c>code:module_status/1</c> returns the status for a
+ module. In the shell and in <c>c</c> module, <c>mm/0</c>
+ is short for <c>code:modified_modules/0</c>, and
+ <c>lm/0</c> reloads all currently loaded modules that
+ have changed on disk.</p>
+ <p>
+ Own Id: OTP-14059</p>
+ </item>
+ <item>
+ <p>
+ Introduce an event manager in Erlang to handle OS
+ signals. A subset of OS signals may be subscribed to and
+ those are described in the Kernel application.</p>
+ <p>
+ Own Id: OTP-14186</p>
+ </item>
+ <item>
+ <p> Sockets can now be bound to device (SO_BINDTODEVICE)
+ on platforms where it is supported. </p> <p> This has
+ been implemented e.g to support VRF-Lite under Linux; see
+ <url
+ href="https://www.kernel.org/doc/Documentation/networking/vrf.txt">
+ VRF </url>, and GitHub pull request <url
+ href="https://github.com/erlang/otp/pull/1326">#1326</url>.
+ </p>
+ <p>
+ Own Id: OTP-14357 Aux Id: PR-1326 </p>
+ </item>
+ <item>
+ <p>
+ Added option to store shell_history on disk so that the
+ history can be reused between sessions.</p>
+ <p>
+ Own Id: OTP-14409 Aux Id: PR-1420 </p>
+ </item>
+ <item>
+ <p> The size of crash reports created by
+ <c>gen_server</c>, <c>gen_statem</c> and <c>proc_lib</c>
+ is limited with aid of the Kernel application variable
+ <c>error_logger_format_depth</c>. The purpose is to limit
+ the size of the messages sent to the <c>error_logger</c>
+ process when processes with huge message queues or states
+ crash. </p> <p>The crash report generated by
+ <c>proc_lib</c> includes the new tag
+ <c>message_queue_len</c>. The neighbour report also
+ includes the new tag <c>current_stacktrace</c>. Finally,
+ the neighbour report no longer includes the tags
+ <c>messages</c> and <c>dictionary</c>. </p> <p> The new
+ function <c>error_logger:get_format_depth/0</c> can be
+ used to retrieve the value of the Kernel application
+ variable <c>error_logger_format_depth</c>. </p>
+ <p>
+ Own Id: OTP-14417</p>
+ </item>
+ <item>
+ <p> One of the ETS tables used by the <c>global</c>
+ module is created with <c>{read_concurrency, true}</c> in
+ order to reduce contention. </p>
+ <p>
+ Own Id: OTP-14419</p>
+ </item>
+ <item>
+ <p>
+ Warnings have been added to the relevant documentation
+ about not using un-secure distributed nodes in exposed
+ environments.</p>
