+## Release 8.9 LTS Upgrade Notes
**GitHub Enterprise compatibility**
SonarQube 8.9 only supports GitHub Enterprise 2.21+ for pull request decoration (the previous minimum version was 2.15).
**Security Hotspots: dedicated space and workflow**
* The Security Hotspots have a brand new space where developers can perform security reviews. The review process has been simplified. It's no longer necessary to transform a Security Hotspot into a Manual Vulnerability and back. A developer can now simply mark a Security Hotspot as Safe, Fixed, or leave it as-is if more time is needed. ([MMF-1868](https://jira.sonarsource.com/browse/MMF-1868)).
* Manual Vulnerabilities created from Security Hotspots are migrated to Security Hotspots with the status "To Review". A comment "Migrated from Manual Vulnerability" is added to the review history to recognize them.
+* The formula to compute the Security Review Rating, which was previously only available at the portfolio level, has been updated to be more meaningful. Historical values for this indicator have been removed to avoid confusion. ([MMF-1890](https://jira.sonarsource.com/browse/MMF-1890)).
* A Security Hotspots Reviewed metric has been added and is available to Quality Gates along with the Security Review Rating.
