I am/was on a Small Plan but it is not available anymore. What is the difference between that and your Team plan?

We released new pricing plans a few years ago that are all described here.

The Team plan is the same price as the Small plan, but you gain access to newer features like Discover, Dashboards, Performance Monitoring and future features that we won’t release on the “older” plans. The only difference in price is for on-demand spending. You can find a detailed analysis of our pricing here.
