+## [0.10.0]
+- API incompatible change: upgrade `hashbrown` to 0.15 (thank you @djc!).
+- API incompatible change: we now wrap `DefaultHashBuilder` and `DefaultHasher`
+  from `hashbrown` so that in the future upgrading `hashbrown` is not an API
+  incompatible change (thank you @djc!).

 ## [0.9.1]
