+	    Fix changing terminal parameters in to_erl</p>
+          <p>
+	    Change the behaviour of to_erl to use TCSADRAIN instead
+	    of TCSANOW when changing terminal parameters. This makes
+	    the serial driver wait for the output queues to be empty
+	    before applying the terminal parameter change. Thanks to
+	    Stefan Zegenhagen.</p>

+	    The default value of {flush, boolean()} in erlang:halt/2
+	    is documented to be 'true' if the status is an integer.
+	    The implementation behaviour was reversed. The
+	    Implementation is now corrected to adhere to the
+	    documentation. Thanks to Jose Valim for reporting the
+	    error.</p>

+	    Fix serious race bug in R16B01 that could cause PID
+	    mix-ups when a lot of processes were spawned and
+	    terminated in a very rapid pace on an SMP emulator with
+	    at least two scheduler threads.</p>

+	    Opening a new compressed file on Windows could in rare

+	    Add erl option to set schedulers by percentages. </p>
+          <p>
+	    For applications where measurements show enhanced
+	    performance from the use of a non-default number of
+	    emulator scheduler threads, having to accurately set the
+	    right number of scheduler threads across multiple hosts
+	    each with different numbers of logical processors is
+	    difficult because the erl +S option requires absolute
+	    numbers of scheduler threads and scheduler threads online
+	    to be specified.</p>
+          <p>
+	    To address this issue, add a +SP option to erl, similar
+	    to the existing +S option but allowing the number of
+	    scheduler threads and scheduler threads online to be set
+	    as percentages of logical processors configured and
+	    logical processors available, respectively. For example,
+	    "+SP 50:25" sets the number of scheduler threads to 50%
+	    of the logical processors configured, and the number of
+	    scheduler threads online to 25% of the logical processors
+	    available. The +SP option also interacts with any
+	    settings specified with the +S option, such that the
+	    combination of options "+S 4:4 +SP 50:50" (in either
+	    order) results in 2 scheduler threads and 2 scheduler
+	    threads online.</p>

+	    Extend erl_driver interface with lock names</p>
+          <p>
+	    Lock and thread names are already a feature in the driver
+	    interface. This extension will let developers read these
+	    names which eases debugging.</p>
