-* `"allocator_api"` feature now uses either unstable API from `std` or 
-  `allocator-api2` crate - a mirror of the unstable API usable on stable.
+* New `"allocator-api2"` feature enables use of allocator API on stable.
+  This feature uses a crate that mirrors the API of
+  unstable `allocator_api` feature.

+  This allows `Bump` to be used as allocator for collection types from
+  `allocator-api2` and any other crates that support `allocator-api2`.
