api/CHANGELOG.md

@@ -27,6 +27,7 @@ All notable changes to the **Prowler API** are documented in this file.
 
 ### Fixed
 - Scans no longer fail when findings have UIDs exceeding 300 characters; such findings are now skipped with detailed logging [(#9246)](https://github.com/prowler-cloud/prowler/pull/9246)
+- Refresh output report timestamps for each scan [(#9272)](https://github.com/prowler-cloud/prowler/pull/9272)
 
 ### Security
 - Django updated to the latest 5.1 security release, 5.1.14, due to problems with potential [SQL injection](https://github.com/prowler-cloud/prowler/security/dependabot/113) and [denial-of-service vulnerability](https://github.com/prowler-cloud/prowler/security/dependabot/114) [(#9176)](https://github.com/prowler-cloud/prowler/pull/9176)
