One important feature added in 2.40/2.41 for watching movies
"For DTS playback on DVD-Video and Blu-ray Disc media, DTS-ES and DTS 96/24 for DVD-Video and DTS-ES Matrix for Blu-ray Discs are now supported.*
* "DTS" is a trademark of DTS Inc."
They always supported Basic (CORE) DTS and for the last several releases supported DTS-HD and DTS-HD Master audio. But until now had not supported DTS-ES, and DTS 96/24.
And one minor feature
"Upscaling of Blu-ray Disc (BDAV) video content is now supported"
PS: I have been able to verify the new DTS features, but not the the Upscaling of BDAV.
