 *Edge*
 
+* Changed the X-Runtime header to report in milliseconds [DHH]
+
+* Changed BenchmarkHelper#benchmark to report in milliseconds [DHH]
+
+* Changed logging format to be millisecond based and skip misleading stats [DHH]. Went from:
+
+    Completed in 0.10000 (4 reqs/sec) | Rendering: 0.40000 (40%) | DB: 0.04000 (4%) | 200 OK [http://example.com]
+
+  ...to:
+  
+    Completed in 100.00ms (View: 400.00, DB: 40.00) | 200 OK [http://example.com]
+
 * Add support for shallow nesting of routes. #838 [S. Brent Faulkner]
