+# v0.5.0
+
+New features:
+
+- MetadataV15 support
+- `AsMetadata` trait now requires milder implementation, so that it is usable on shortened metadata
+- `AsCompleteMetadata` trait should be used instead now for full functionality (parsing of unchecked extrinsics)
+
+API changes:
+
+- What used to be `AsMetadata` might need to become `AsCompleteMetadata`, see above
+
 # v0.4.0
