+### Enhancements
+
+* Added SHA224, SHA384 and SHA512 support for validating downloaded sources.
+
+### Bug fixes
+
+* If multiple hashing algorithms are used to validate a downloaded source, a `RuntimeError` will now be thrown if **any** of those hashes are incorrect. This is stricter and more consistent than the previous behaviour.
