MySQL 8.0.20 support?

Hi all, 
we updated our MySQL servers to the latest 8.0.20 version. From change notes: 
To address this issue, the redo log format was modified to reduce redo log record size for modifications to undo tablespaces.
Now when we run our backup, it fails with this error: 
Using server version 8.0.20
xtrabackup: uses posix_fadvise().
xtrabackup: cd to /var/lib/mysql
xtrabackup: open files limit requested 0, set to 1024
xtrabackup: using the following InnoDB configuration:
xtrabackup:   innodb_data_home_dir = .
xtrabackup:   innodb_data_file_path = ibdata1:12M:autoextend
xtrabackup:   innodb_log_group_home_dir = ./
xtrabackup:   innodb_log_files_in_group = 2
xtrabackup:   innodb_log_file_size = 1073741824
Number of pools: 1
Unknown redo log format (4). Please follow the instructions at http://dev.mysql.com/doc/refman/8.0/en/ upgrading-downgrading.html.
xtrabackup: Error: recv_find_max_checkpoint() failed.
Any ideas of workaround until new version of Xtrabackup?
