 - An error is no longer thrown during command execution when the application under test overwrites the `window.$` property with a non-function. Fixes [#1502](https://github.com/cypress-io/cypress/issues/1502). Fixed in [#32682](https://github.com/cypress-io/cypress/pull/32682).
 - When running `cypress` in Cypress development environments, or when `ELECTRON_ENABLE_LOGGING` is otherwise set to 1, certain messages written to `stderr` will no longer be bracketed with verbose tags. Addresses [#32569](https://github.com/cypress-io/cypress/issues/32569). Addressed in [#32674](https://github.com/cypress-io/cypress/pull/32674).
+- Improve performance of time between specs by not resetting the `file_systems` `StorageType` state when executing the CDP command `Storage.clearDataForOrigin`. Fixed in [#32703](https://github.com/cypress-io/cypress/pull/32703).
