主要改进如下：

• Cannot save configuration on UI of related Nodes
  

• isAuthorized() Exception: Can not close file with id 0 because it is still in use
  

• NoClassDefFoundError on shutdown
  

• OrientDB support in IBM Cloud
  

• Long running application using OPartitionedDatabasePool causing a OTokenSecurityException: missing session and token
