 build as patches to your installation using the 'otp_patch_apply'
 tool. For information on install requirements, see descriptions for
 each application version below.

 --- HIGHLIGHTS ------------------------------------------------------
 ---------------------------------------------------------------------

  OTP-15691    Application(s): snmp
               Related Id(s): ERIERL-324

               [snmp|agent] Add a get-mechanism callback module (and a
               corresponding behaviour). The agent calls this module
               to handle each get (get, get-next and get-bulk)
               request.

 --- POTENTIAL INCOMPATIBILITIES -------------------------------------
 ---------------------------------------------------------------------

  OTP-15717    Application(s): common_test
               Related Id(s): ERIERL-334

               The test result when a hook function fails is in
               general the same as if the function that the hook is
               associated with fails. For example, if
               post_init_per_testcase fails the result is that the
               test case is skipped, as is the case when
               init_per_testcase fails.This, however, was earlier not
               true for timetrap timeouts or other error situations
               where the process running the hook function was killed.
               This is now corrected, so the error handling should be
               the same no matter how the hook function fails.

 --- Fixed Bugs and Malfunctions ---

  OTP-15551    Application(s): erts, otp

               Fixes of install/release phase in build system.

               -- The source tree was modified when
               installing/releasing and/or applying a patch.

               -- Some files were installed with wrong access rights.

  OTP-15657    Application(s): erts, otp, tools

               Minor fixes for make clean.

               *** POTENTIAL INCOMPATIBILITY ***

               The test result when a hook function fails is in
               general the same as if the function that the hook is
               associated with fails. For example, if

  OTP-15758    Application(s): common_test
               Related Id(s): ERIERL-342

               In some rare cases, when two common_test nodes used the
               same log directory, a timing problem could occur which
               caused common_test to crash because it's log cache file
               was unexpectedly empty. This is now corrected.


 --- Improvements and New Features ---

  OTP-14746    Application(s): common_test
               Related Id(s): ERIERL-143

               Two new common_test hook functions are introduced:

               post_groups/2, which is called after Suite:groups/0
               post_all/3, which is called after Suite:all/0

               These functions allow modifying the return values from
               the groups/0 and all/0 functions, respectively.

               A new term, {testcase,TestCase,RepeatProperties} is now
               also allowed in the return from all/0. This can be used
               for repeating a single test case a specific number of
               times, or until it fails or succeeds once.


  OTP-15716    Application(s): common_test

               OTP internal test improvements.

  OTP-15660    Application(s): erts
               Related Id(s): ERL-869

               Fixed a bug in all ets:select* and ets:match* functions
               that could in some rare cases lead to very poor
               performance.


  OTP-15690    Application(s): erts
               Related Id(s): PR-2172

               Fix a possible deadlock when terminating the ERTS
               caused by a dirty scheduler not releasing it's
               run-queue lock when terminating.


  OTP-15766    Application(s): erts

               Add missing documentation of new external tags NEW_PID,
               NEW_PORT and NEWER_REFERENCE introduced in OTP 19.

               These new tags are planned to be "activated" in OTP 23
               when distribution capability flag DFLAG_BIG_CREATION
               becomes mandatory. Older nodes (>= 19) are able to
               decode these new tags and send them back to the new
               node. Nodes older than OTP 23 will however never encode
               their own local pids, ports and references using the
               new tags.

       -- public_key-1.5.2 (first satisfied in OTP 20.2)


 --- Fixed Bugs and Malfunctions ---

  OTP-15763    Application(s): ssh

               If a client was connected to an server on an already
               open socket, the callback fun(PeerName,FingerPrint) in
               the accept_callback option passed the local name in the
               argument PeerName instead of the remote name.
