   They have a default width of three buckets, with each bucket being 20 seconds wide. This means
   only the last 60 seconds of a histogram -- in 20 second granularity -- will contribute to the
   quantiles emitted.
 
   We'll expose the ability to tune these values in the future.

 ## [0.9.0] - 2022-03-10
 
 ### Added

 ### Changed

 - Updated various dependencies in order to properly scope dependencies to only the necessary feature
   flags, and thus optimize build times and reduce transitive dependencies.
 - Updated to the new handle-based design of `metrics`.
