submit a pull request for the Metacello project on github[1] and update 
the method MetacelloSqueakPlatform>>defaultPlatformAttributes[2] with 
your new Squeak versions added to the list ...

If you want to avoid having to update Metacello for each new Squeak 
release, add something along the lines of what pharo has been doing for 
a few years[3] ... then you only need to remember to update that method 
... but at least it will be part of the base image ...

For GemStone I've included code to generate the default attributes for 
GemStone based on the GemStone version number ...
