+	    A simple socket API is provided through the socket
+	    module. This is a low level API that does *not* replace
+	    gen_[tcp|udp|sctp]. It is intended to *eventually*
+	    replace the inet driver, but not the high level
+	    gen-modules (gen_tcp, gen_udp and gen_sctp). It also
+	    provides a basic API that facilitates the implementation
+	    of other protocols, than TCP, UDP and SCTP. </p>
+          <p>
+	    Known issues are; No support for the Windows OS
+	    (currently).</p>

+	    The dist messages EXIT, EXIT2 and MONITOR_DOWN have been
+	    updated with new versions that send the reason term as
+	    part of the payload of the message instead of as part of
+	    the control message.</p>
+          <p>
+	    The old versions are still present and can be used when
+	    communicating with nodes that don't support the new
+	    versions.</p>

+	    Kernel configuration parameter <c>start_distribution =
+	    boolean()</c> is added. If set to <c>false</c>, the
+	    system is started with all distribution functionality
+	    disabled. Defaults to <c>true</c>.</p>

+          <p>
+	    In OTP-21.3, a warning was introduced for duplicated
+	    applications/keys in configuration. This warning would be
+	    displayed both when the configuration was given as a file
+	    on system start, and during runtime via
+	    <c>application:set_env/1,2</c>.</p>
+          <p>
+	    The warning is now changed to a <c>badarg</c> exception
+	    in <c>application:set_env/1,2</c>. If the faulty
+	    configuration is given in a configuration file on system
+	    start, the startup will fail.</p>
