No, we didn't make any changes here - the built in demo license should have 2 sessions of RealSpeak built into it - I just checked my 4.0(2) release and my 4.0(3) pre release versions and both offer 2 sessions of TTS and I'm able to assign Users to a class of service that has TTS enabled.
Where are you seeing that it has no tts licenses? In the License Info Viewer applet out of the tools depot? Or somewhere else?
