Release notes for PS and PXC 8.0.31 says audit_log_flush is deprecated but it seems not

Hi Team,

Release notes for PS and PXC 8.0.31 says audit_log_flush is deprecated  but it seems not the case.

Our documents :

https://docs.percona.com/percona-server/8.0/release-notes/8.0.31-23.html

https://docs.percona.com/percona-xtradb-cluster/8.0/release-notes/8.0.31-23.html

 says :

"The audit_log_flush variable has been deprecated and will be removed in future releases."

It looks like a mistake in documentation,  as there are no commits related to audit_log_flush since October 2022, when this commit was pushed to the tree: https://github.com/percona/percona-server/commit/953c14e90df417e969905657a1f349d89ddb710d

We can see other related commits here: https://github.com/percona/percona-server/search?o=desc&q=audit+log+flush&s=committer-date&type=commits

As per upstream document, it is replace by function audit_log_rotate : https://dev.mysql.com/doc/refman/8.0/en/audit-log-reference.html#sysvar_audit_log_flush

But we cannot find the said function :

We cannot also find the function in  the source code :
