+## 0.3.0
+
+- Fixed panic when a corrupted hash is passed to `rcrypt::verify`
+- (BREAKING): `RcryptError::WrongSize` now has two `usize` tuple fields: one with expected has
+  size, and the other with
+- (BREAKING): `RcryptError::UnsupportedHash` is now `UnsupportedHashPrefix`
+
 ## 0.2.0
 
 - Fixed hash generation for hashes with a cost of 9
