 ## 1.0.0.0  -- 2017-10-28
 
 * First version. Released on an unsuspecting world.
+
+## 1.0.0.1  -- 2018-06-10
+
+* Used Stack to test different versions of GHC.
+* Removed {-# OPTIONS_GHC -fno-warn-unused-top-binds #-} from Cl3.hs to better support earlier versions of GHC, and it was no longer needed.
+* Loosened version bound for QuickCheck to work better with earlier versions of Stackage LTS snapshots.
+* Improved spectraldcmp's documentation to clairify that spectraldcmp requires an implementation of the real, imaginary, and complex implememtation of the function.
