I think this might refer to a "v2" of the examples, not of ChucK. The wording is indeed a bit confusing.

On the bright side; I quickly skimmed a random sampling and everything I saw should work with your current version. As long as you have 1.2.1.3 (the current one) installed you should be fine and able to run them, change them, get better noises and/or interesting errors. So, in a way the V2 that you would love is here already for you to enjoy

Yours,
