 Improvements
 
 - readJournal, when not given a file name, now always assumes it is "-" rather than "(string)".
   [#2328]
+- Reader's rReadFn has changed type (for the new CSV text encoding feature);
+  it now takes a `Handle` rather than a `Text`, allowing more flexibility.
 - Make test/unittest.hs more buildable; remove PackageImports that was causing
   trouble for ghci.
