innobackupex & MySQL Versions

Hi ,
I tried to find a document that points which MySQL Version - innobackupex X Supported.
Most important is the MySQL 4.0.2.7 on machine : CentOS release 5.2 /Kernel 2.6.18-92.el5 - x86_64

But i will be very glad if someone could post the Innobacupex Supported MySQL List ( Rhel 5+6 64 bit)

These are my MySQL Versions, the Database combined with tables on InnoDB & tables with MyISAM , so i’m working with innobackupex hot backup.
4.0.27
5.0.50
5.0.72sp1
5.0.77
5.1.45
5.1.61
5.1.68
5.1.70
5.6.12

Thank You ,

Alex

The documentation states:

Also on the same documentation, xtrabackup (includes innobackupex) are built using codebase from innodb51, innodb55, innodb56, xtradb55, and xtradb56, so its safe to say that xtrabackup/innobackupex works on 5.1/5.5/5.6 versions of MySQL/Percona Server.
