+	    new tags are planned to be "activated" in OTP 23 when
+	    distribution capability flag <c>DFLAG_BIG_CREATION</c>
+	    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.</p>

+	    <p>A new logging API is added to Erlang/OTP, see the
+	    <seealso
+	    marker="kernel:logger"><c>logger(3)</c></seealso> manual
+	    page, and section <seealso
+	    marker="kernel:logger_chapter">Logging</seealso> in the
+	    Kernel User's Guide.</p>
+	    <p>Calls to <c>error_logger</c> are automatically
+	    redirected to the new API, and legacy error logger event
+	    handlers can still be used. It is, however, recommended
+	    to use the Logger API directly when writing new code.</p>
+	    <p>Notice the following potential incompatibilities:</p>
+	    <list> <item><p>Kernel configuration parameters
+	    <c>error_logger</c> still works, but is overruled if the
+	    default handler's output destination is configured with
+	    Kernel configuration parameter <c>logger</c>.</p> <p>In
+	    general, parameters for configuring error logger are
+	    overwritten by new parameters for configuring
+	    Logger.</p></item> <item><p>The concept of SASL error
+	    logging is deprecated, meaning that by default the SASL
+	    application does not affect which log events are
+	    logged.</p> <p>By default, supervisor reports and crash
+	    reports are logged by the default Logger handler started
+	    by Kernel, and end up at the same destination (terminal
+	    or file) as other standard log event from Erlang/OTP.</p>
+	    <p>Progress reports are not logged by default, but can be
+	    enabled by setting the primary log level to info, for
+	    example with the Kernel configuration parameter
+	    <c>logger_level</c>.</p> <p>To obtain backwards
+	    compatibility with the SASL error logging functionality
+	    from earlier releases, set Kernel configuration parameter
+	    <c>logger_sasl_compatible</c> to <c>true</c>. This
+	    prevents the default Logger handler from logging any
+	    supervisor-, crash-, or progress reports. Instead, SASL
+	    adds a separate Logger handler during application start,
+	    which takes care of these log events. The SASL
+	    configuration parameters <c>sasl_error_logger</c> and
+	    <c>sasl_errlog_type</c> specify the destination (terminal
+	    or file) and severity level to log for these
+	    events.</p></item></list>
+          <p>
+	    Since Logger is new in Erlang/OTP 21.0, we do reserve the
+	    right to introduce changes to the Logger API and
+	    functionality in patches following this release. These
+	    changes might or might not be backwards compatible with

+	    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 <c>post_init_per_testcase</c>
+	    fails the result is that the test case is skipped, as is
+	    the case when <c>init_per_testcase</c> 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
