Yeah, I read that, but it's late summer already ;)

Oh great!!! That's what I was looking for :)

I guess so :D it works with my older apps. But I have a threads in this last app/game so I have to figure out the way how to use the thread() :

No.

I guess that's why 0199 is not mentioned in the download section. Also see the note on googlecode:

We are currently doing significant work in removing and adding features as we head toward 2.0. Do not use the SVN trunk if you need anything remotely stable.

I found that the opengl2 from the build 0198, pre-release 0199 or build 0200 fixes some things but is still unstable.

So you solve one problem but get something else in return. Which is to be expected for the reason mentioned in the quote.

As others I'm looking forward to 2.0 but we just have to be patient. It'll be worth it even though losing P2D/P3D will probably break some stuff.

See my answer to your duplicate question in the https://forum.processing.org/topic/using-the-thread-method topic. The stop method on threads is deprecated.
