+<!-- API changelog requirements - delete this before merging -->- Replace all instances of X.X.X in the frontmatter with the appropriate API spec.- Replace all instances of 2019-01-01 with the production release date for the API.- All items in the changelog should mention which endpoints are affected.- For changes and bugfixes, describe the previous behavior AND the new behavior.
+<!-- Where to put things - delete this before merging -->Some heuristics for which heading to put API reference updates under:
+*Added*- New endpoints.- New fields in the request or a response of an existing endpoint.
+*Changed*- Changes in the behavior of an existing endpoing, when the previous behavior was working as it was designed. In other words, non-bugfix changes.
+*Fixes*- Bugfixes: Changes to the behavior of an endpoint, where the previous behavior was not working as intended/expected/documented.
+<!-- Sample syntax - delete this before merging -->
+- References to an endpoint should be in this format: `the Endpoint Name ([VERB /path/to/endpoint/{endpointVariable}](https://developers.linode.com/api/docs/v4/{endpoint}/{#endpointVariable})) endpoint` *Example*: `the Clone Linode ([POST /linode/instances/{linodeId}/clone](https://developers.linode.com/api/v4/linode-instances-linode-id-clone/#post)) endpoint`
