+_Released 03/15/2023_
+
+**Bugfixes:**
+
+- Fixed a regression in Cypress [10](/guides/references/changelog#10-0-0) where
+  the reporter auto-scroll configuration inside user preferences was
+  unintentionally being toggled off. Users must now explicitly enable/disable
+  auto-scroll under user preferences, which is enabled by default. Fixes
+  [#24171](https://github.com/cypress-io/cypress/issues/24171) and
+  [#26113](https://github.com/cypress-io/cypress/issues/26113).
+
+**Dependency Updates:**
+
+- Upgraded [`ejs`](https://www.npmjs.com/package/ejs) from `3.1.6` to `3.1.8` to
+  address this
+  [CVE-2022-29078](https://github.com/advisories/GHSA-phwq-j96m-2c2q) NVD
+  security vulnerability. Addressed in
+  [#25279](https://github.com/cypress-io/cypress/pull/25279).
