     > - According to [CentOS Linux EOL](https://blog.centos.org/2023/04/end-dates-are-coming-for-centos-stream-8-and-centos-linux-7/), the upstream support for CentOS Linux 7 ended on June 30, 2024.
     >     - Before upgrading TiDB, make sure to check your operating system version. TiDB v8.4.0 DMR and v8.5.0 removed the support of glibc 2.17, and dropped support and testing with CentOS Linux 7. It is recommended to use Rocky Linux 9.1 or a later version. Upgrading a TiDB cluster on CentOS 7 to v8.4.0 or v8.5.0 will cause the risk of cluster unavailability.
-    >     - Starting from v8.5.1, to assist users still running CentOS Linux 7, TiDB resumes the support of glibc 2.17, resumes testing of CentOS Linux 7, and is now compatible with CentOS Linux 7. However, due to the EOL status of CentOS Linux, it is strongly recommended that you review the [official announcements and security guidance](https://www.redhat.com/en/blog/centos-linux-has-reached-its-end-life-eol) for CentOS Linux 7 and migrate to an operating system supported by TiDB for production use, such as Rocky Linux 9.1 or later.
