Hello all, I have just uploaded version 1.5.0 of the Haskell version to hackage. The links for the three pieces are: http://hackage.haskell.org/package/protocol-buffers http://hackage.haskell.org/package/protocol-buffers-descriptor http://hackage.haskell.org/package/hprotoc This catches up to Google's version 2.1.0, as described below: * Support for "repeated" fields for primitive type (good arrays!). Note that using on an invalid field type will generate an error. * NO support yet for the *_FIELD_NUMBER style constants * It is now an error to define a default value for a repeated field. * Fields can now be marked deprecated (does nothing) * The type name resolver will no longer resolve type names to fields. Note that this applies to type of normal and extension fields. A lexer bug was founds and fixed by George van den Driessche, when a numeric literal in a proto file was followed immediately by a newline character. Cheers, Chris
