  - Fixed a compatibility issue so that component test projects can use [Vite](https://vitejs.dev/) version 4.2.0 and greater. Fixes [#26138](https://github.com/cypress-io/cypress/issues/26138).
  - Changed the way that Git hashes are loaded so that non-relevant runs are excluded from the Debug page. Fixes [#26058](https://github.com/cypress-io/cypress/issues/26058).
+ - Fixed an issue where Vite component tests sometimes fail in CI due to not being able to dynamically import the component support or spec modules. Fixes [#25913](https://github.com/cypress-io/cypress/issues/25913).
