+	    healthy gcc atomics or libatomic_ops was detected.</p>

+	    Ensure 'erl_crash.dump' when asked for it. This will
+	    change erl_crash.dump behaviour.</p>
+          <p>
+	    * Not setting ERL_CRASH_DUMP_SECONDS will now terminate
+	    beam immediately on a crash without writing a crash dump
+	    file.</p>
+          <p>
+	    * Setting ERL_CRASH_DUMP_SECONDS to 0 will also terminate
+	    beam immediately on a crash without writing a crash dump
+	    file, i.e. same as not setting ERL_CRASH_DUMP_SECONDS
+	    environment variable.</p>
+          <p>
+	    * Setting ERL_CRASH_DUMP_SECONDS to a negative value will
+	    let the beam wait indefinitely on the crash dump file
+	    being written.</p>
+          <p>
+	    * Setting ERL_CRASH_DUMP_SECONDS to a positive value will
+	    let the beam wait that many seconds on the crash dump
+	    file being written.</p>
+          <p>
+	    A positive value will set an alarm/timeout for restart
+	    both in beam and in heart if heart is running.</p>

+	    a bitstring with a size not a multiple of 8, either no
+	    exception was generated or an incorrect exception was
+	    generated. (Thanks to Adam Rutkowski for reporting this

+	    The runtime system could crash while scheduling a port
+	    task. The port task was scheduled either due to an
+	    external I/O event being triggered, a driver timeout
+	    being triggered, or data being sent over a distribution
+	    channel.</p>

+	    A faulty spec for process_info/2 could cause false
+	    dialyzer warnings. The spec is corrected.</p>

+	    In very rare cases, the VM could crash if a garbage
+	    collector was called while executing an appending bit
+	    syntax instruction. The symptom was a core when
+	    reallocating memory in the function erts_bs_append. The
+	    garbage collector bug is now corrected.</p>

+	    Due to a race condition on Windows, sometimes when
+	    printing to standard output and then immediately
+	    terminating erlang all data would not be printed. The
+	    emulator now waits for all data to be printed before
+	    exiting.</p>
