This topic describes the release notes for Realtime Compute for Apache Flink. The release notes include the updates on the Ververica Runtime (VVR) engine versions and corresponding Apache Flink and Apache Paimon versions, release dates, and platform updates.
Engine updates
The evaluations on the VVR engine indicate that VVR 8.0.1 and 8.0.3 occasionally cause data loss in specific scenarios. This affects data accuracy. In this case, Alibaba Cloud decides to announce the End of Support (EOS) for VVR 8.0.1 and 8.0.3. We recommend that you upgrade your deployments to VVR 8.0.5 or later at the earliest opportunity. For information, see Upgrade the engine version of a deployment. Alibaba Cloud provides necessary support and guidance to help you smoothly upgrade your deployments to a more secure and stable version. Thank you for your understanding and cooperation.
For more information about the savepoint compatibility across Flink versions, see Compatibility Table.

For information about the description of VVR version numbers, see Engine version.
For information about the version mappings for change data capture (CDC) connectors between VVR and Apache Flink, see CDC connectors for Apache Flink.
During the version iteration of the VVR engine, the final minor version of a major VVR version is the version of long-term support (LTS). For example, the final minor version of VVR 6.x is VVR 6.0.7. In this case, the LTS version of VVR 6.x is VVR 6.0.7. Only two LTS versions are maintained by Alibaba Cloud. If a new LTS version is released, the oldest LTS version no longer provides services. This indicates that you cannot select this VVR version when you create a new deployment of Realtime Compute for Apache Flink.
If a VVR version has critical security or stability issues, Alibaba Cloud shortens the RLP of the version to three months to avoid severe impact on business caused by this version, and notify the involved users by using the Realtime Compute for Apache Flink console or by sending announcements in a timely manner to update the version.
