+	    <p>Fixed a number of bugs that caused faulty stack-traces
+	    to be generated. The faulty stack traces were generated
+	    either when applying the following functions or tracing
+	    the following functions:</p> <list>
+	    <item><c>erlang:error/1</c></item>
+	    <item><c>erlang:error/2</c></item>
+	    <item><c>erlang:exit/1</c></item>

+	    Fix <c>process_info(Pid, current_stacktrace)</c> to use
+	    stack depth limit set by
+	    <c>system_flag(backtrace_depth)</c>. The old behavior was
+	    a hard coded depth limit of 8.</p>

+	    A process calling <seealso

+	    Fixed a bug in call-time trace for NIFs which caused
+	    tracing to erroneously be started multiple times for one
+	    call.</p>

+	    Fix bug in tracing of garbage collection that could cause
+	    VM crash. Bug exists since OTP 19.0.</p>

+	    Fix bug in <c>binary_to_term</c> for binaries created by
+	    <c>term_to_binary </c> with option <c>compressed</c>. The
+	    bug can cause <c>badarg</c> exception for a valid binary
+	    when Erlang VM is linked against a <c>zlib</c> library of
+	    version 1.2.9 or newer. Bug exists since OTP 17.0.</p>

+	    <p>NIF resources was not handled in a thread-safe manner
+	    in the runtime system without SMP support.</p>
+	    <p>As a consequence of this fix, the following driver
+	    functions are now thread-safe also in the runtime system
+	    without SMP support:</p> <list>
+	    <item><p><c>driver_free_binary()</c></p></item>

+	    Fix <c>erlang:round/1</c> for large floating point
+	    numbers with an odd absolute value between <c>(1 bsl
+	    52)</c> and <c>(1 bsl 53)</c>. The result was falsely
+	    calculated as the next higher even number even though all
+	    integer values up to <c>(1 bsl 53)</c> can be represented
+	    as floats with full precision.</p>

+          <p>
+	    Add size of literals to module code size in crash dump
+	    and <c>(l)oaded</c> command in break menu like it used to
+	    be before OTP-19.0.</p>

+	    Fix potential bug in <c>enif_send</c> when called without
+	    a process context and with argument <c>msg_env</c> as
+	    <c>NULL</c>.</p>
+          <p>

+	    Fix bug where passing an appendable binary to
+	    <c>erlang:port_control()</c> could crash the emulator.</p>

+	    A received SIGTERM signal to beam will generate a
+	    <c>'stop'</c> message to the <c>init</c> process and
+	    terminate the Erlang VM nicely. This is equivalent to
+	    calling <c>init:stop/0</c>.</p>
