+ Fix evaluation in matching of bound map key variables in
+ the interpreter.</p>

+ evaluate: <c>X = key,(fun(#{X := value}) -&gt; true
+ end)(#{X => value})</c></p>

+ <p> The Erlang Code Linter no longer crashes if there is

+ <item>
+ <p>
+ The timestamp in the result returned by <c>dets:info(Tab,
+ safe_fixed)</c> was unintentionally broken as a result of
+ the time API rewrites in OTP 18.0. This has now been
+ fixed.</p>
+ <p>
+ Own Id: OTP-13239 Aux Id: OTP-11997 </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>
