Today’s release contains a lot of changes under the hood to improve standard compliance and interoperability with other implementations. There are also a lot of small bug fixes for bugs reported by users. This release also contains some smaller API enhancements especially for the .NET API. Be aware that the server side API changed at one point – the WriteAccessHandler that is used to inform the server application that some writable data attributes are accessed. The signature of these callback has changed! There is now a user defined parameter to simplify application design. Also the return value changed so the application designer can control the return code of the negative WriteData response. Don’t forget to change your application accordingly when updating to this release. Please see also the CHANGELOG for additional information about new features and changes.
