Hi PRof. I've purchased a module in the past which said it worked on 7.2.1 but actually didn't.
It's only ever been one, but still, the module was important enough to hold back features of the website that were needed.
Am raising this only to say that you can't trust the filtering system to guarantee working modules, even when the developers say they are.
This thread could still be useful for people to ask and confirm before a purchase is made - or start up a new thread to that effect.
with the number of available modules that do work with 7.2 - the list would almost be endless - wait - there is already a section of modules - and on the left - there is a filter icon - click that and you can filter by dolphin versions.
