Breaking changes


See changelog.


The Append block children endpoint returns a list of new Block object children instead of the parent block.

Array rollup property types changed from file, text and person to files, rich_text and people.

Property IDs are now encoded to be URL safe.

Empty number, email, select, date, and rollup properties are now returned in page responses as null.

More information


Rich text property values use the type rich_text instead of text.
