+* Detects stuck AMD Ryzen RDRAND and correctly treats as an error [PR #67](https://github.com/corretto/amazon-corretto-crypto-provider/pull/67)
+* When initialized with an `int`,`KeyPairGenerator` for "EC" keys now always uses "secp*r1" curves.
   This matches the behavior of SunEC.
-  **This changes the curves selected for 192 and 256 from secp192k1 to secp192r1/P-192 and secp256k1 to secp256r1/P-256 respectively.**
+  **This changes the curves selected for 192 from secp192k1 to secp192r1/P-192, and curves selected for 256 from secp256k1 to secp256r1/P-256.**
+  [PR #68](https://github.com/corretto/amazon-corretto-crypto-provider/pull/68)
 
 ### Maintenance
