+* Changes in 13.10
+
+- Small fix for haskell-simple-indent: Certain indentation situations
+  cause valname-string to be nil, which haskell-trim did not handle
+  gracefully (naturally, since nil != "").
+
+- Luke Hoersten's Shnippet merged in under snippets/.
+
+- haskell-presentation-mode is now a haskell-mode derived mode.
+
+- Small improvement to haskell-process-do-info (works on constructors
+  now and underscored names).
+
+- Add haskell-indent-spaces configuration variable.
+
+- The command string to run cabal commands is slightly more
+  configurable. See: C-h f haskell-process-do-cabal-format-string
+
