Few day old Puppy user with Slacko64 6.3.2. Upgrade from 14.1 to 14.2 sources?

I can see a whole list of 14.2 .pet files and Slackware 14.2 stuff here, but I can't figure out the process to go through to edit sources in Puppy Package Manager. puppy-slacko64 14.1 official appears to be hard coded, however there is a puppy-slacko6414.2-official listed at the above link, as well as a puppy-slacko-7.0 that I don't see any reference to at the official Puppy download site. Any advice would be welcome.
