+# Changelog
+
+## 0.1.0 (2024-01-15)
+
+This is the initial release of the Hierarchical Unified Graph Representation.
+See the representation specification available at [hugr.md](https://github.com/CQCL/hugr/blob/main/specification/hugr.md).
+
+This release includes an up-to-date implementation of the spec, including the core definitions (control flow, data flow and module structures) as well as the Prelude extension with support for basic classical operations and types.
+
+HUGRs can be loaded and stored using the versioned serialization format, or they can be constructed programmatically using the builder utility.
+The modules `hugr::hugr::view` and `hugr::hugr::rewrite` provide an API for querying and mutating the HUGR.
+For more complex operations, some algorithms are provided in `hugr::algorithms`.
