No need to worry now, but there's always a chance down the road Davis changes code making it incompatible.
If Steve releases the software code someone may keep it going but no guarantee.
This goes for any 3rd party software including website scripts. People retire or just move on so will someone keep updating scripts and software to meet the changes?
I use CumulusMX with my WMR200. I like it a lot. I was worried when Steve decided to retire but he released the source and others have taken up the software maintenance. The website is
https://cumulus.hosiene.co.uk. I too like its simplicity.
