[newbie] Mandrake version 5.3 ?

[Tomasz Wzietek]

Hello,

Just a general question regarding the numbering scheme of the OS
releases. As found on the official Mandrake web page:

"Linux -Mandrake 5.x is 100% compatible with RedHat 5.x! (note: 5.3 is
an exception: Mandrake 5.3 is compatible with RH 5.2 since RH 5.3 is not
out and will probably never be)"

My question is: how do you know and why (if not) is RedHat 5.3 not going
to be released?

Thank you,
Tomasz
