It appears Blocs 5 has dropped support for Pulse CMS. I tried it once and frankly it wasn’t for me. Volt on the other hand is a good solution for many purposes.
If you see the latest beta of Blocs 5 the licence now automatically switches when you start Blocs on another machine, which I assume requires an internet connection. It looks like this essentially means you can install Blocs on various machines, but only work on one at a time with a licence, which I imagine would be OK for most of us. Currently I only have it installed on one Mac, so cannot verify this.
