+_2022 October 13_
+
+go-ipld-prime's release policy says that:
+
+> even numbers should be easy upgrades; odd numbers may change things
+
+The major change in this release is a bump to Go 1.18, and as such we're suggesting this should be an "easy upgrade".
+
+#### 🛠 Breaking Changes
+
+Update go.mod to Go 1.18.
+
+#### 🔦 Highlights
+
+* **Codecs**: [Correct JSON codec Bytes handling](https://github.com/ipld/go-ipld-prime/pull/472). This change does not impact DAG-JSON, which is the generally recommended codec for JSON output as the JSON codec cannot properly handle Bytes or Links.
+* **Dependencies**:
+  * Update to [email protected]: https://github.com/multiformats/go-multihash/releases/tag/v0.2.1
+  * Update to [email protected]: https://github.com/multiformats/go-multicodec/releases/tag/v0.6.0
