| 39 | +## Highlights |
| 40 | + |
| 41 | +This release is a bugfix release only and contains a critical fix for a regression found in YuniKorn 1.6.0 and YuniKorn 1.6.1. |
| 42 | +The only other changes included are updates for dependencies related to CVEs. **All users of 1.6.0 and 1.6.1 are urged to upgrade.** |
| 43 | + |
| 44 | +### Re-introduction of race condition |
| 45 | + |
| 46 | +**Critical**: A change included in YuniKorn 1.6.0 and YuniKorn 1.6.1 re-introduces a race condition fixed in YuniKorn 1.4.0. |
| 47 | +The regression was caused by a partial revert of the fix from [YUNIKORN-1993](https://issues.apache.org/jira/browse/YUNIKORN-1993) |
| 48 | +Fixed in [YUNIKORN-3036](https://issues.apache.org/jira/browse/YUNIKORN-3036). |
| 49 | + |
| 50 | +### CVE fixes |
| 51 | + |
| 52 | +YuniKorn 1.6.2 is now build with Go 1.23.7. The standard libraries from Go are also updated. |
| 53 | + |
| 54 | +The Kubernetes version YuniKorn builds with is not updated. The CVEs fixed in the upgraded Kubernetes versions are not relevant. |
| 55 | +The code affected is either not used in YuniKorn or only affect Microsoft Windows which is not a supported operating system. |
