-## Breaking Improvements
-
-- Generated CloudEvents will use the user-provided Partial<CloudEvent> to infer other fields. #146
-  - For storage events, updating the Partial's `bucket` will update:
-    - `data.bucket`
-    - Parts of `source`, `data.selfLink`, `data.id`
-  - For PubSub events, updating the Partial's `data.message.json` will:
-    - generate a new base64 string for `data.message.data`
-      - (But a user-provided `data.message.data` still takes priority)
-
