v4.1.7

This release updates the TS types to work correctly with TS 4.9, which made a change that broke the existing MergeParameters type implementation. Happily, the TS team provided a better (and simpler!) MergeParameters implementation. Since that only works with TS 4.7+, we've reworked the internals to handle providing the old implementation to TS 4.2..4.6, and the new implementation to TS 4.7 and greater.

As a user, there should be no visible change - just update to 4.1.7.
