There is a new version of the Haskell implementation of Google's protocol buffer message serialization format. Performance for serialization has been improved in this release. The new code is up on hackage at http://hackage.haskell.org/package/protocol-buffers http://hackage.haskell.org/package/protocol-buffers-descriptor http://hackage.haskell.org/package/hprotoc The darcs repository is at http://code.haskell.org/protocol-buffers/ The changes in 2.0.5 compared to 2.0.2 are: * Specialize some encoding during serialization to improve performance * Add some options that protoc handles and that were missing in hprotoc * Alter the namespace resolution in hprotoc to better match protoc * Improve error handling during name resolution in hprotoc * Lex and parse the new aggregate options in Google version 2.4.0 Note that the new aggregate syntax in Google's version 2.4.0 is not supported. The change allows the new notation to be parsed and a clear error message to be reported. -- Chris Kuklewicz
