Haskell Mode has a new logo designed by Kristof. Documentation in HTML looks much better. Presentation mode received a lot of improvements. Code jumping supports multiple buffers. Hasktags can be used on Windows. Syntax highlighting shows quasiquotes as strings.

ghc-mod officially depends on haskell-mode.

There was also usual stream of backward and forward compatibility fixes, code cleanup, regression tests and plugged holes, usability and efficiency fixes.
