+This is a patch release in response to a 2023-06-28 email from Kurt Hornik about
+inputs to numeric_version() and package_version().
+
+In this case, the problematic inputs came from implicit usage via `>` in some
+tests and these have been changed to comparison to character or removed
+entirely.
+
+I did NOT rerun reverse dependency checks because usethis's last patch release
+was less than 2 weeks ago, also in response to a request from Kurt Hornik about
+numeric versions.
