 _Released 11/18/2025 (PENDING)_
 
+**Features:**
+
+ - The `experimentalRunAllSpecs` option can now be used for component testing as well as e2e testing. Addresses [#25636](https://github.com/cypress-io/cypress/issues/25636).
+
 **Bugfixes:**
 
 - Fixed an issue where top changes on test retries could cause attempt numbers to show up more than one time in the reporter and cause attempts to be lost in Test Replay. Addressed in [#32888](https://github.com/cypress-io/cypress/pull/32888).
