 Pretty library change log.
 
+========= Version 4.0, 24 August 2011 ==========
+
+* Big change to the structure of the library. Now we don't have a fixed
+  TextDetails data type for storing the various String types that we
+  support. Instead we have changed that to be a type class that just
+  provides a way to convert String and Chars to an arbitary type. This
+  arbitary type is now provided by the user of the library so that they
+  can implement support very easily for any String type they want.
+
+  This new code lives in Text.PrettyPrint.Core and the Text.PrettyPrint
+  module uses it to implement the old API. The Text.PrettyPrint.HughesPJ
+  module has been left unchanged for a compatability module but deprecated.
 
 ========= Version 3.0, 28 May 1987 ==========
