 # Changelog
 
-## Unreleased (xxxx-xx-xx)
+## 0.3.0 (2024-04-15)
 
-This release includes multiple breaking changes to the API, including the rename of the crate from `quantinuum_hugr` to `hugr`.
+### Main changes
+
+This release includes a long list of breaking changes to the API.
+
+- The crate was renamed from `quantinuum_hugr` to `hugr`.
+- The API has been simplified, flattening structures and reworking unnecessarily
+  fallible operations where possible.
+- Includes version `1` of the hugr serialization schema. Older pre-v1 serialized
+  hugrs are no longer supported. Starting with `v1`, backward compatibility for
+  loading older versions will be maintained.
