SCO Openserver 5.0.5

[Programma Computer Snc]

I'd like to upgrade my 3.22.16a-gamma release of mysql to 3.22.27 on a Sco
Openserver 5.0.5 ,Intel system.
on http://www.mysql.com/download_3.22.html I haven't found any binary
distribution for this O.S., but on http://www.mysql.com/download_3.23.html
I've found a 3.22.27 contributed binary.
Is this release stable ?
Can I safety install this on my server ?.

Thankyou
