The biggest change is some of the less sexy stuff, like scale and security. E.g. we're now able to scale to 100M+ MAU companies with 100M+ items, and we have a completely tenant isolated architecture, with security as a top priority.
We've also made the platform more configurable and lower levels and we've found that people like choosing their own models and experimenting rather than just relying on our system.
Finally, we launched search only a couple of months ago and are currently heavily focused on building a best-in-class experience there.
