Important changes to V1.0
- Rename UA_NodeClass to UA_NodeClassMask
- Enum value changed in UAIdentifierType
- Extend UAMonitoredSettings with parameter QueueSize
- Depricated Structed Data Type UANodeInfo
- The graphical representation of the order of the outputs of the FB’s have been harmonized: Done, Busy, Error; ErrorID, then general outputs, and finaly the VAR_IN_OUTs. For this reason we separate between V1.0 and V1.1 in the compliance list as seen in the Appendix A.

- Moved these Functionsblocks into new chapter “Phased out Functionsblocks”:
- UA_NamespaceGetIndex
- UA_TranslatePath
- UA_NodeGetHandle, UA_ReleaseHandle, UA_NodeGetInfo
- UA_SubscriptionOperate
- UA_MonitoredItemAdd, UA_MonitoredItemRemove, UA_MonitoredItemOperate
- UA_Read, UA_Write
- UA_MethodeGetHandle, UA_MethodeReleaseHandle

New functionality:

- Created new Structured Data Type UANodeInformation
- Created new Functionblocks with “List” functionality
- UA_NamespaceGetIndexList, UA_ServerGetIndexByUriList,
- UA_TranslatePathList
- UA_NodeGetHandleList, UA_NodeReleaseHandleList
- UA_NodeGetInformation
- UA_MonitoredItemAddList, UA_MonitoredItemRemoveList
- UA_MonitoredItemModifyList, UA_MonitoredItemOperateList
- UA_MethodeGetHandleList, UA_MethodReleaseHandleList
- UA_EventItemAdd, UA_EventItemOperate, UA_EventItemRemove

- UA_HistoryUpdate

Added Appendix
about Compliance procedure and make use of of PLCopen OPC UA logo
