This version primarily fixes a potential deadlock issue during the startup process related to the Raft protocol initialization in version 2.4.1 (#12526). It also rolls back the changes made in version 2.4.1 that lowered the hessian version, which caused startup problems on JDK 17+ versions due to conflicts with hessian dependencies. Additionally, the logic for checking ServerStatus has been optimized to prevent issues from affecting the availability of non-Raft-dependent functionalities due to Raft election failures.

Furthermore, this version includes several usability enhancements and addresses some other bugs.

Please see the details of the changes below:
