+## 13.3.3
+
+_Released 10/24/2023 (PENDING)_
+
+**Bugfixes:**
+
+- Fixed a regression in [10.0.0](#10.0.0), where search would not find a spec if the file name contains "-" or "\_", but search prompt contains " " instead (e.g. search file "spec-file.cy.ts" with prompt "spec file"). Fixes [#25303](https://github.com/cypress-io/cypress/issues/25303).
