 ### Fixes
 
+- `[expect, @jest/expect-utils]` `ObjectContaining` support `sumbol` as key ([#14414](https://github.com/jestjs/jest/pull/14414))
 - `[expect]` Remove `@types/node` from dependencies ([#14385](https://github.com/jestjs/jest/pull/14385))
 - `[jest-core]` Use workers in watch mode by default to avoid crashes ([#14059](https://github.com/facebook/jest/pull/14059) & [#14085](https://github.com/facebook/jest/pull/14085)).
 - `[jest-reporters]` Update `istanbul-lib-instrument` dependency to v6. ([#14401](https://github.com/jestjs/jest/pull/14401))
