 - Edge cases where `cy.intercept()` would not properly intercept and asset response bodies would not properly be captured for test replay have been addressed. Addressed in [#27771](https://github.com/cypress-io/cypress/issues/27771).
 - Fixed an issue where `enter`, `keyup`, and `space` events where not triggering `click` events properly in some versions of Firefox. Addressed in [#27715](https://github.com/cypress-io/cypress/pull/27715). 
+- Fixed a regression in `13.0.0` where tests using Basic Authorization can potentially hang indefinitely on chromium browsers. Addressed in [#27781](https://github.com/cypress-io/cypress/pull/27781)
