+ Fix bug where gethostname would incorrectly fail with
+ enametoolong on Linux.</p>
+ <p>
+ Own Id: OTP-14310</p>

+ <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>.
