Thanks for this. I have seen this page, and the link to the on-prem just brings you to the download links and some more screenshots, but nothing definitive.

I have been concerned about our on-prem 7.5 and the fact that future development has been put on hold, which smells as EOL for the legacy HD. My source: State of Desktop app v8.0

If you scroll to the bottom of the page, it mentions the state (or fate) of V7.5. They are not coming right out and saying, but it ‘feels’ like we are being pushed to the cloud version or the Help Desk Server version.
