September 13, 2025

We released v5.1.0 of @notionhq/client, our SDK for JavaScript and TypeScript. This includes the following fixes and improvements:

• Add support for is_locked boolean parameter on update page and database APIs (to update whether a page is locked in the Notion app UI)
• dataSource.update: add support for changing a data source's parent database
• Remove page_id as a possible parent for CreateDataSourceBodyParameters
• Add request_id to Client log lines
  As noted in the library's README, v5 and above of the SDK isn't compatible with API versions older than 2025-09-03. See the upgrade guide to learn more.
