 ======================
 Unreleased
 ----------
+
+v6.15.0
+----------
 * Added Lists support (`Client.lists`, `/v3/lists`): list, create, find, update, and delete lists, plus `list_items`, `add_items`, and `remove_items` for `/v3/lists/{list_id}/items`, with typed request/response models in `nylas.models.lists`
 * Added Manage Domains (`Client.domains`, `/v3/admin/domains`): list, create, find, update, delete, `get_info`, and `verify` with models in `nylas.models.domains`; optional `ServiceAccountSigner` (`nylas.handler.service_account`) for service-account headers (`X-Nylas-Kid`, `X-Nylas-Nonce`, `X-Nylas-Timestamp`, `X-Nylas-Signature`) on each `Domains` method; new `cryptography` dependency, RSA signing, and `HttpClient` `serialized_json_body` so signed payloads match the wire body
 * Added Transactional Send: `Client.transactional_send.send()` for `POST /v3/domains/{domain_name}/messages/send`, with `TransactionalSendMessageRequest` and `TransactionalTemplate` models (JSON and multipart send behavior aligned with grant `messages.send`)
