 #### Version 5
 
-Work on HtmlUnit-CSSParser 5.0 has started. This new major version will require **JDK 17 or higher**.
+Starting with version 5.0.0, **JDK 17 or higher is required**.  
+If you are still on JDK 8, see [Legacy Support (JDK 8)](#legacy-support-jdk-8) below.
 
 
-#### Legacy Support (JDK 8)
-
-If you need to continue using **JDK 8**, please note that versions 4.x will remain available as-is. However,
-**ongoing maintenance and fixes for JDK 8 compatibility are only available through sponsorship**.
-
-Maintaining separate fix versions for JDK 8 requires significant additional effort for __backporting__, testing, and release management.
-
-**To enable continued JDK 8 support**, please contact me via email to discuss sponsorship options. Sponsorship provides:
-
-- __Backporting__ security and bug fixes to the 4.x branch
-- Maintaining compatibility with older Java versions
-- Timely releases for critical issues
-
-Without sponsorship, the 4.x branch will not receive updates. Your support ensures the long-term __sustainability__ of this project across multiple Java versions.
