Can I install packages only for my release?

[Rahul Fernandez]

Hi, I'm am running 4.9 release. A package called hpijs1.4.1 is
installed. I now would like to upgrade to hpijs-1.5. However, this
package is only available in 4.9-stable. Can I install the package
from 4.9-stable or is it advisable to stick to the packages in my
release? Thanks, Rahul
