+ --- HIGHLIGHTS ------------------------------------------------------
+ ---------------------------------------------------------------------
+
+  OTP-13397    Application(s): erts
+
+               Add support for Erlang Distribution protocol to split
+               the payload of large signals into several fragments.
+               This allows other processes to communicate
+               uninterrupted during the transmission of these signals.
+
+
+  OTP-14894    Application(s): compiler
+               Related Id(s): ERL-714
+
+               The compiler has been rewritten to internally use an
+               intermediate representation based on Static Single
+               Assignment (SSA). The new intermediate representation
+               makes more optimizations possible.
+
+               Most noticeable is that the binary matching
+               optimizations are now applicable in many more
+               circumstances than before.
+
+               Another noticeable change is that type optimizations
+               are now applied across local function calls, and will
+               remove a lot more redundant type tests than before.
+
+
+  OTP-15055    Application(s): ssl
+
+               Use new logger API in ssl. Introduce log levels and
+               verbose debug logging for SSL.
+
+
+  OTP-15128    Application(s): erts, stdlib
+
+               ETS option write_concurrency now also affects and
+               improves the scalability of ordered_set tables. The
+               implementation is based on a data structure called
+               contention adapting search tree, where the lock
+               granularity adapts to the actual amount of concurrency
+               exploited by the applications in runtime.
+
+
+  OTP-15439    Application(s): erts
+
+               The length/1 BIF used to calculate the length of the
+               list in one go without yielding, even if the list was
+               very long. In OTP 22, length/1 will yield when called
+               with a long lists.
+
+
+  OTP-15456    Application(s): compiler
+
+               All compiler options that can be given in the source
+               file can now also be given in the option list or from
+               the command line for erlc.
+
+               Specifically, the option
+               {nowarn_deprecated_function,MFAs} was only recognized
+               when given in the file with the attribute -compile().
+               The option {nowarn_unused_function,FAs} was incorrectly
+               documented to only work in a file, but it also worked
+               when given in the option list.
+
+
+  OTP-15575    Application(s): tools
+
+               The cover tool now uses the counters module instead of
+               ets for updating the counters for how many times a line
+               has been executed. By default, Cover will work with
+               distributed nodes, but a new function
+               cover:local_only/0 allows running the Cover in a
+               restricted but faster local-only mode.
+
+               The increase in speed will vary depending on the type
+               of code being cover-compiled, but as an example, the
+               compiler test suite runs more than twice as fast with
+               the new Cover.
+
+
+ ---------------------------------------------------------------------
+ --- POTENTIAL INCOMPATIBILITIES -------------------------------------
+ ---------------------------------------------------------------------
+
+  OTP-15381    Application(s): stdlib
+
+               The gen_* behaviours have been changed so that if
+               logging of the last N messages through sys:log/2,3 is
+               active for the server, this log is included in the
+               terminate report.
+
+               To accomplish this the format of "System Events" as
+               defined in the man page for sys has been clarified and
+               cleaned up, a new function sys:get_log/1 has been
+               added, and sys:get_debug/3 has been deprecated. Due to
+               these changes, code that relies on the internal badly
+               documented format of "System Events", need to be
+               corrected.
+
+
+  OTP-15571    Application(s): reltool
+
+               A new element, Opts, can now be included in a rel tuple
+               in the reltool release specific configuration format:
+               {rel, Name, Vsn, RelApps, Opts}.
+
+               This supports the use of {rel, Name, Vsn, RelApps,
+               [{load_dot_erlang, false}]} to prevent the boot script
+               from running the .erlang file.
+
+               The incompatibilities are as follows:
+
+               * The return from reltool:get_config/1 and
+               reltool:get_config/3 includes the new rel tuple for all
+               rels where the load_dot_erlang option is set to false.
+               * The return from reltool:get_config/3 includes the new
+               rel tuple for ALL rels if the InclDefs parameter is set
+               to true.
+
+
+  OTP-15613    Application(s): erts
+
+               All external pids/ports/refs created by
+               erlang:list_to_pid and similar functions now compare
+               equal to any other pid/port/ref with the same number
+               from that node.
+
+               Before this change they compared differently because
+               the node creation of the pid/port/ref did not compare
+               equal to any real pid/port/ref creation.
+
+
+  OTP-15621    Application(s): erl_interface, otp
+
+               The limited support for VxWorks is deprecated as of OTP
+               22, and will be removed in OTP 23.
+
+
+  OTP-15622    Application(s): erl_interface
+
+               The old legacy erl_interface library (functions with
+               prefix erl_) is deprecated as of OTP 22, and will be
+               removed in OTP 23. This does not apply to the ei
+               library. Reasonably new gcc compilers will issue
+               deprecation warnings. In order to disable these
+               warnings, define the macro EI_NO_DEPR_WARN.

+
+               A new rand module algorithm, exro928ss
+               (Xoroshiro928**), has been implemented. It has got a
+               really long period and good statistical quality for all
+               output bits, while still being only about 50% slower
+               than the default algorithm.
+
+               The same generator is also used as a long period
+               counter in a new crypto plugin for the rand module,
+               algorithm crypto_aes. This plugin uses AES-256 to
+               scramble the counter which buries any detectable
+               statistical artifacts. Scrambling is done in chunks
+               which are cached to get good amortized speed (about

+               A new rand module algorithm, exro928ss
+               (Xoroshiro928**), has been implemented. It has got a
+               really long period and good statistical quality for all
+               output bits, while still being only about 50% slower
+               than the default algorithm.
+
+               The same generator is also used as a long period
+               counter in a new crypto plugin for the rand module,
+               algorithm crypto_aes. This plugin uses AES-256 to
+               scramble the counter which buries any detectable
+               statistical artifacts. Scrambling is done in chunks
+               which are cached to get good amortized speed (about
+               half of the default algorithm).
