+* `rand` dependency has been upgraded to 0.8

+* Allow using the owned `String` type for `phf` dynamic code generation
+
+## 0.8.0
+
+* `phf_macros` now works on stable.
+* :tada: Fixed asymptotic slowdowns when constructing maps over very large datasets (+1M keys)
+* (**breaking change**) The `core` features of `phf` and `phf_shared` have been changed to `std` default-features.
+* (**breaking change**) The types in `phf_codegen` can be used with formatting macros via their `Display` impls and the `build()` methods no longer take `&mut Write`.
+* Support has been added for using 128-bit integers as keys.
+* (**breaking change**) The `OrderedMap` and `OrderedSet` types and the `phf_builder` crate have been removed due to lack of use.
+* Byte strings now work correctly as keys.
+* `unicase` dependency has been upgraded to 2.4.0
