+ The functionality utilized by BIFs for temporary
+ disabling of garbage collection while yielding could
+ cause system task queues to become inconsistent on a
+ process executing such a BIF. Process system tasks are
+ for example utilized when purging code, garbage
+ collecting literal data, and when issuing an ordinary
+ garbage collection from another process.</p>
+ <p>
+ The bug does not trigger frequently. Multiple code purges
+ in direct sequence makes it more likely that this bug is
+ triggered. In the cases observed, this has resulted in a
+ hanging code purge operation.</p>

+ Fix the Erlang distribution to handle the scenario when a

+ can not handle the atom cache. This bug only affects
+ users that have implemented a custom distribution
+ carrier. It has been present since OTP-21.</p>

+ </item>
+ <item>
+ <p>EEP-52 has been implemented.</p>
+ <p>In binary matching, the size of the segment to be
+ matched is now allowed to be a guard expression, and
+ similarly in map matching the keys can now be guard
+ expressions. See the Erlang Reference Manual and
+ Programming Examples for more details.</p>
+ <p>Language compilers or code generators that generate
+ Core Erlang code may need to be updated to be compatible
+ with the compiler in OTP 23. For more details, see the
+ section Backwards Compatibility in <url
+ href="http://erlang.org/eeps/eep-0052.html">EEP
+ 52</url>.</p>

+ <item>
+ <p>Internally in BEAM, handling of continuation pointers
+ has been simplified. This change is not user-visible,
+ except when examing a process stack in the crashdump
+ viewer. The continuation pointer for a function will now
+ be stored below the y(0) for that function.</p>

+ <p>
+ Increased size of node incarnation numbers (aka
+ "creation"), from 2 bits to 32 bits. This will reduce the
+ risk of pids/ports/refs, from different node incarnation
+ with the same name, being mixed up.</p>
+ <p>
+ Own Id: OTP-15603</p>
+ </item>
+ <item>
+ <p>The runtime system can now encode Erlang terms to the
+ Erlang external term format as I/O vectors. The main
+ benefit of this is that reference counted binaries can be
+ referred to directly instead of copied into a new
+ binary.</p> <p>The default Erlang distribution over TCP
+ will always utilize this. Alternate distribution
+ implementations utilizing a port as distribution
+ controller will utilize this if the driver implements the
+ <seecref
+ marker="erts:driver_entry#outputv"><c>outputv</c></seecref>
+ callback. Alternate Erlang distribution implementations
+ utilizing a process as distribution controller will
+ utilize this if I/O vectors are utilized by the
+ functionality that processes the data returned from
+ <seemfa
+ marker="erts:erlang#dist_ctrl_get_data/1"><c>erlang:dist_ctrl_get_data()</c></seemfa>.</p>
+ <p>The return type for data returned by <seemfa
+ marker="erts:erlang#dist_ctrl_get_data/1"><c>erlang:dist_ctrl_get_data()</c></seemfa>
+ has been changed from <c>iodata()</c> to <c>iovec()</c>.
+ Note that <c>iovec()</c> data is valid <c>iodata()</c> so
+ old implementations using
+ <c>erlang:dist_ctrl_get_data()</c> do not need to be
+ changed, but may benefit from being changed depending on
+ usage scenario.</p> <p>The new BIFs <seemfa
+ marker="erts:erlang#term_to_iovec/1"><c>term_to_iovec/1</c></seemfa>
+ and <seemfa
+ marker="erts:erlang#term_to_iovec/2"><c>term_to_iovec/2</c></seemfa>
+ have been introduced. These work exactly as
+ <c>term_to_binary()</c> with the corresponding arity
+ except the return type.</p>
+ <p>
+ Own Id: OTP-15618</p>
+ </item>
+ <item>
+ <p>Improved ETS scalability of concurrent calls that
+ change the size of a table, like <c>ets:insert/2</c> and
+ <c>ets:delete/2</c>.</p> <p>This performance feature was
+ implemented for <c>ordered_set</c> in OTP 22.0 and does
+ now apply for all ETS table types.</p> <p>The improved
+ scalability may come at the cost of longer latency of
+ <c>ets:info(T,size)</c> and <c>ets:info(T,memory)</c>. A
+ new table option <c>decentralized_counters</c> has
+ therefore been added. It is default <c>true</c> for
+ <c>ordered_set</c> with <c>write_concurrency</c> enabled
+ and default <c>false</c> for all other table types.</p>

+ <p>The possibility to run Erlang distribution without
+ relying on EPMD has been extended. To achieve this a
+ couple of new options to the inet distribution has been
+ added.</p> <taglist> <tag>-dist_listen false</tag>
+ <item>Setup the distribution channel, but do not listen
+ for incoming connection. This is useful when you want to
+ use the current node to interact with another node on the
+ same machine without it joining the entire
+ cluster.</item> <tag>-erl_epmd_port Port</tag>
+ <item>Configure a default port that the built-in EPMD
+ client should return. This allows the local node to know
+ the port to connect to for any other node in the
+ cluster.</item> </taglist> <p>The <c>erl_epmd</c>
+ callback API has also been extended to allow returning
+ <c>-1</c> as the creation which means that a random
+ creation will be created by the node.</p>
+ <p>In addition a new callback function called
+ <c>listen_port_please</c> has been added that allows the
+ callback to return which listen port the distribution
+ should use. This can be used instead of
+ <c>inet_dist_listen_min/max</c> if the listen port is to
+ be fetched from an external service.</p>
