+# Release 0.2.0

+- [Discriminant matching is now simplified][10], casting values directly by
+  name, rather than trying to compute offsets from known values manually.
+- **breaking change**: [Derivations now import the traits from `num-traits`][11]
+  instead of the full `num` crate.  These are still compatible, but users need
+  to have an explicit `num-traits = "0.2"` dependency in their `Cargo.toml`.

 # Release 0.1.44
 
 - [The derived code now explicitly allows `unused_qualifications`][9], so users
   that globally deny that lint don't encounter an error.
