These notes are designed for users of previously released versions of Jayrock up to, but not including, v0.9.8316. It is not a comprehensive list of breaking changes. For additional help with breaking compilations, post your issue to the Jayrock discussion group.
Jayrock assembly has been permanently split into two assemblies.
                The Jayrock assembly now mainly contains all types related to services
                and JSON-RPC. The other assembly, called Jayrock.Json, is used by 
                    Jayrock and contains types and functionality related to the JSON data
                format. The Jayrock assembly therefore depends on Jayrock.Json and both
                must be deployed together for the JSON-RPC functionality. To work with the JSON data
                format without any relation to JSON-RPC, only Jayrock.Json is needed.Jayrock.Json.Rpc namespace has been renamed to Jayrock.JsonRpc.
                You must update all references in source and configuration files from the previous
                namespace to the new one.JArray, JObject and JNull from
                the Jayrock.Json namespace have been renamed to JsonArray,
                JsonObject and JsonNull, respectively.Jayrock.Json.Rpc.JsonRpcParamsAttribute has been removed. Instead,
                just use the regular params 
                keyword from C# (ParamArray
                in Visual Basic).IJsonFormatter has been replaced by Jayrock.Json.Conversion.IExporter, which continues to serve a similar purpose.IJsonFormattable has been replaced by Jayrock.Json.Conversion.IJsonExportable, which continues to serve a similar purpose.JsonParser, JsonReader.DeserializeNext and IParseOutput have been
                removed. Use JsonConvert.Import from the Jayrock.Json.Conversion
                namespace instead for similar functionality.JsonWriter.WriteValue has been
                removed. Use JsonConvert.Export from the Jayrock.Json.Conversion
                namespace instead for similar functionality.jayrock/json.rpc has been renamed to 
                jayrock.jsonrpc. Jayrock will still pick up the section under
                the old name, but you are advised to move to the new name as soon as
                possible.
