Interesting - seems like a pretty big change in licensing, the free "Make" version is now only licensed for non-commercial work: http://help.sketchup.com/en/article/3000023

Was it actually always this way that the free version was not supposed to be used for commercial work, or is that new now?

<< or is that new now?

it's new now, in the past one free version was authorised, then the next year not etc...

Now It's clear, it's not! :)

Checked it, I can't find any new major features. All the main modeling features is still available only by plugins..

You right: ilt's only a transition version :)

Speed is improved for big files and goes twice or more for the plugin Artisan for example ;)
