    v2 v3  
    1212   * Generalised list comprehensions
    1313   * View patterns
    14  
    15  * GHC now comes with haddock 2, which supports all GHC extensions
    1614
    17  * The garbage collector can now use multiple parallel threads, making garbage collection faster on multi-core machines.
     15 * '''Type families''' have been completely re-implemented, by Manuel Chakravarty, along the lines of our ICFP 2008 paper [http://research.microsoft.com/%7Esimonpj/papers/assoc-types/index.htm Type checking with open type functions] --- only simpler.  As a result, we believe that type families work reliably in GHC 6.10.  There is one missing feature, however, namely the ability to have equalities in the superclass context of a class.   We'll add that to the HEAD in the next few months.
