This paper has two different parts. In its first part, the changes done within the Tango kernel since the last Icalepcs conference will be described. The second part will focus on the foreseen evolution of the so-called Tango event system (asynchronous communication between client and server). Since its beginning, within Tango, this type of communication is implemented using a CORBA notification service implementation called omniNotify. This will be replaced by a new system based either on a home made design using Tango synchronous request or based on an implementation of the DDS (Data Distribution Service). The final choice is not done at the time of writing this abstract. The reason of the change and the final choice will be described. A first feedback of the new implementation will also be given.
