+History Range Glob feature
+==========================
+
+Previously, when using ``%history`` users could specify either
+a range of sessions and lines, for example:
+
+``~8/1-~6/5`` see history from the first line of 8 sessions ago,
+              to the fifth line of 6 sessions ago.
+
+Or users could specify ``-g <pattern>`` to glob ALL history for
+the specified pattern.
+
+However users could **\ *not*\ ** specify both.
+If a user did specify both a range, and a glob pattern,
+then the glob pattern would be used *but the range would be ignored*.
+
+With this enhancment, if a user specifies both a range and a glob pattern,
+the glob pattern will be applied to the specified range of history.
