We released another minor update to DSP Link 1.65 last week. There is some improved support for recovering when an application crashes, as well as a couple bug fixes.
Please review the "What's New" section in the release notes for the change log for this, and previous releases.
This release is appropriate for DVSDK environments, and is not applicable for EZSDK 5.x users.
We still aren't actively developing DSP Link, but occasionally take opportunities like this to roll up a few interesting fixes/features our customers find (and even submit fixes for!).
