[**Notion**](<https://creatorstoolbox.com/tools/notion>) announced [**JS SDK updates**](<https://developers.notion.com/page/changelog#august-13-2026>) on August 13, 2026.

## What changed

@notionhq/client v5.25.1 fixes the isFullDataSource and isFullDatabase type guards, which previously accepted partial responses and narrowed them to the full type. Both now require the title field, the same structural check the other full-object guards use. isFullPageOrDataSource picks up the fix. v5.25.2 adds the does\_not\_equal condition to verification property filters in data source and database query request types, alongside the existing status condition.
