I'm wondering if anybody out there has what changes were made to the GS3, when they were made, and what the part numbers are if you want to keep up to date. Kind of like a 'changelog' for the gs3. If not, is there any interest in doing something like this?

I just found out last week that one of the over pressure valves has a new design which helps divert water into the drain box instead of the brain box. While my board wasn't toasted, it still would have been nice to know so I could manually make the change myself. I'm curious to hear other improvements over the years to this machine.

I summarized most of the changes in the La Marzocco GS/3 MP Review based on La Marzocco's "out of the box" presentation. Going forward, the support link on the La Marzocco US website has a section for tech bulletins and you can subscribe to them.

Thank you for this information. This is exactly what I was looking for!
