+which has been only slightly modified to allow it to be built as a Portable 
+Class Library (PCL).
+
+## Changes
+
+Due to a lack of support for `System.SerializableAttribute` in .NET PCLs 
+currently, serialization support has simply been removed for now. I intend to
+revisit this in the future and put together a PCL-compatible equivalent.
+
+The `TrueTypeFont` constructor overload accepting a filename string has been
+changed to accept a Stream instead. This is again to be PCL-compatible.
