+[Coverage]
+
+  An oneshot_lines mode is added.  [Feature #15022]
+  This mode checks "whether each line was executed at least once or not",
+  instead of "how many times each line was executed".
+  A hook for each line is fired at most once, and after it is fired,
+  the hook flag was removed, i.e., it runs with zero overhead.
+
+  [New options]
+
+    * Add +:oneshot_lines+ keyword argument to Coverage.start.
+
+    * Add +:stop:+ and +:clear:+ keyword arguments to Coverage.result.
+      If +clear+ is true, it clears the counters to zero.
+      If +stop+ is true, it disables coverage measurement.
+
+  [New methods]
+
+    * Coverage.line_stub, which is a simple helper function that
+      creates the "stub" of line coverage from a given source code.
