+ entire runtime system and create a crash dump. Corrected
+ to generate an error exception in the calling
+ process.</p>
+ <p>Also corrected specs for code loading functions and
+ added more information in the documentation about the
+ error reasons returned by code-loading functions.</p>

+ Time warp safety improvements.</p>
+ <p>
+ Introduced the options <c>monotonic_timestamp</c>, and
+ <c>strict_monotonic_timestamp</c> to the trace,
+ sequential trace, and system profile functionality. This
+ since the already existing <c>timestamp</c> option is not
+ time warp safe.</p>
+ <p>
+ Introduced the option <c>safe_fixed_monotonic_time</c> to
+ <c>ets:info/2</c> and <c>dets:info/2</c>. This since the
+ already existing <c>safe_fixed</c> option is not time
+ warp safe.</p>

+ <p>
+ Add validation callback for heart</p>
+ <p>
+ The erlang heart process may now have a validation
+ callback installed. The validation callback will be
+ executed, if present, before any heartbeat to heart port
+ program. If the validation fails, or stalls, no heartbeat
+ will be sent and the node will go down.</p>
+ <p>
+ With the option <c>'check_schedulers'</c> heart executes
+ a responsiveness check of the schedulers before a
+ heartbeat is sent to the port program. If the
+ responsiveness check fails, the heartbeat will not be
+ performed (as intended).</p>
