I am a little bit curious about Ryan's reasons to licence ProcessWire under GNU/GPL v2 and not under the newer GNU/GPL v3. Is there a special reason for this choice?

Good question. In this case, primarily because TinyMCE is GPL v2, and we include TinyMCE in our distribution. I don't think we can legally GPL v3 something that includes GPL v2 code unless that code's license is worded GPL v2 "or newer". Also, I am not very legal minded and there was a little bit of "go with the flow" and use the same license as WordPress/Drupal, which seemed like a safe thing to do. I couldn't find any GPL v3 licensed CMSs at the time I was figuring out how to license PW, so associated some risk due to the lack of examples.

I understand, although I am not legal minded either.  :)
I noticed that Tinymce is licenced under  LGPL 2.1. As far as I understand things, this would mean that it's possible to use GPL v3 for PW.

I beleive WordPress has GNU v2 or later.

Note: I am not saying that you should change the licence.
