==What's new==

===GF compiler and run-time library===

- The Haskell source code for GF now compiles with GHC 7.6 and hence the
  the latest [Haskell Platform http://www.haskell.org/platform/] (2013.2.0.0).
  Compatibility with GHC 7.4 is also maintained.
- A bug in the partial evaluator that caused problems with pattern macros has
  been fixed.
- The new runtime in C is now stable enough to be used although there
are still features from the Haskell runtime which are not ported yet. 
The new runtime provides the following new features:
     - state of the art statistical parser for GF (PMCFG)
     - the parser is usable in a robust mode, i.e. even if the
     sentence is not in the scope of the grammar it is still possible
     to get a list of parsable chunks
     - the linearizer is also more robust than the one in Haskell since
     it can linearize the partial trees returned from the robust parser
     - the exhaustive generation for GF abstract trees generates the trees
     in decreasing probability order (the order in Haskell is unspecified).
     - we have started using just-in-time compilation to native code in
     the exhaustive generator. The goal is to reach the state where
     GF will provide state of the art theorem prover.
