How does Coinbase update work?

Could you elaborate on the workings of Coinbase's update process? I'm curious to understand how the platform ensures its systems are up-to-date and secure for its users. Do they have a regular schedule for updates? How do they communicate any changes to their users? What steps do they take to ensure the updates don't disrupt the trading experience? Additionally, what kind of testing do they perform before rolling out an update to ensure its stability and compatibility? It would be great to get a high-level overview of the entire update process at Coinbase.
