 [How to use a CHANGELOG](http://keepachangelog.com/)
+## [1.3.1]
+### Fixed
+- Changes made as part of 1.3.0 caused an error to be thrown when ActiveSupport::Duration was used for `limit` or `inc` arguments of accelerating_check
+- Reverted `Math.log` formula for accelerating_check in favor of a more simple formula because the former was worse than the latter
+- Live logging amount of time an operation will be sleeping before sleep occurs
 ## [1.3.0]
 ### Added
 - Say hello to steady_check which sleeps for the increment passed to it
 ### Fixed
 - accelerating_check algorithm was messed up, so now using `log` to better approximate reverse of backoff_check
