+          <p>
+	    Major improvements of the Erlang distribution for Erlang
+	    runtime systems with SMP support. Previously distribution
+	    port locks were heavily contended, and all encoding and
+	    decoding for a specific distribution channel had to be
+	    done in sequence. Lock contention due to the distribution
+	    is now negligible and both encoding and decoding of
+	    Erlang messages can be done in parallel.</p>
+          <p>
+	    The old atom cache protocol used by the Erlang
+	    distribution has been dropped since it effectively
+	    prevented all parallel encoding and decoding of messages
+	    passed over the same distribution channel.</p>
+          <p>
+	    A new atom cache protocol has been introduced which
+	    isolates atom cache accesses and makes parallel encoding
+	    and decoding of messages passed over the same
+	    distribution channel possible. The new atom cache
+	    protocol also use an atom cache size 8 times larger than
+	    before. The new atom cache protocol is documented in the
+	    ERTS users guide.</p>
+          <p>
+	    Erlang messages received via the distribution are now
+	    decoded by the receiving Erlang processes without holding
+	    any distribution channel specific locks. Erlang messages
+	    and signals sent over the distribution are as before
+	    encoded by the sending Erlang process, but now without
+	    holding any distribution channel specific locks during
+	    the encoding. That is, both encoding and decoding can be
+	    and are done in parallel regardless of distribution
+	    channel used.</p>
+          <p>
+	    The part that cannot be parallelized is the atom cache
+	    updates. Atom cache updates are therefore now scheduled
+	    on the distribution port. Since it is only one entity per
+	    distribution channel doing this work there is no lock
+	    contention due to the atom cache updates.</p>
+          <p>
+	    The new runtime system does not understand the old atom
+	    cache protocol. New and old runtime systems can however
+	    still communicate, but no atom cache will be used.</p>
