OK. Got it... MDL = MyDLink. Typo above also corrected.
The support strategy you mentioned would be interesting - i.e. still supporting a phone operating system that is not supported by Microsoft anymore and to stop supporting the newer ones... MDL Lite was still working fine in WP10 (and WP8.1) in March. Yes, I know it's just business as usual not to shed money to software development on the more minor platforms.
Anyway support also for Windows Phone was one of the main reasons to us for purchasing several D-Link cameras during last couple of years.
