Solaris Patch Updates (Kerberos)

Hi,

I have a Solaris 10 device which has quite a dated version of Kerberos 5 installed. I'd like to upgrade the version of Kerberos to a more recent version, but was unsure whether updates to Kerberos are provided by applying a Solaris patch - or whether I would need to go to the MIT website (I've not had much luck finding a Solaris compatible download).

Does the Solaris patch 147793 upgrade the krb5 version number from 1.3 to 1.10?

I checked the readme below, but it doesn't provide any indication that the version is increased:
