 ### Breaking Changes
 
 -   Require Jest v30 or newer and expose the Jest preset from the package root ([#80767](https://github.com/WordPress/gutenberg/pull/80767)).
+-   Add an `exports` field. Only the package root and `jest-preset` are exposed; deep imports of other files are no longer resolvable ([#80837](https://github.com/WordPress/gutenberg/pull/80837)).
