innobackupex support for MySQL 5.7.8

Is there a way to overcome this issue? I’m just testing out the tool.

150818 22:25:14 innobackupex: Connecting to MySQL server with DSN ‘dbi:mysql:;mysql_read_default_group=xtrabackup;mysql_socket=/tmp/mysql.sock’ as ‘root’ (using password: YES).
150818 22:25:14 innobackupex: Connected to MySQL server
innobackupex: Error: Unsupported server version: ‘5.7.8-rc’ (InnoDB version: ‘5.7.8’). Please report a bug at https://bugs.launchpad.net/percona-xtrabackup

I’m facing the same problem with mysql-community-server-5.7.10 and percona-xtrabackup-2.3.3:

version_check Connecting to MySQL server with DSN ‘dbi:mysql:;mysql_read_default_group=xtrabackup;mysql_socket=/data/mysql/mysql.sock’ as ‘username’ (using password: YES).
version_check Connected to MySQL server
version_check Executing a version check against the server…
version_check Done.
Connecting to MySQL server host: localhost, user: username, password: set, port: 0, socket: /data/mysql/mysql.sock
Error: Unsupported server version: ‘5.7.10-log’. Please report a bug at https://bugs.launchpad.net/percona-xtrabackup

Since mysql 5.7 is officially available, it would be nice if xtrabackup would be compatible with mysql 5.7… are you already working on this issue? can you provide an approximate time?
