I get they have our emails. I mean KV331 with Synthmaster actually alert me when they update and so does Harrison Mixbus. And a few others, but then there others who don't as well. I think it is just a matter of some do and some don't. It is up to
you to keep your all your software up to date really.
Studio One users also have the excellent
Studio One Expert site as well and they always alert us to updates. And produce quality videos on them demonstrating the extra features etc..
