I was referring to these comments: "So, for example, `+years` is no longer part of the `date-provider` interface; it's now part of `date-arithmetic-provider`, and values that satisfy `date-period?` also satisfy `date-arithmetic-provider?`." "And `duration-between` was removed in favor of date-period-between, time-period-between, and period-between." The first sounds like a function isn't in a module anymore and the second sounds like a function is just gone. But I didn't look at the code or docs.
