Hi all

It took a while, but we finally got a branch that is stable enough to 
start migrating. Issue is related to cleaning up pthread. Currently I 
added Blender internal workers back. it is slower, but doesn't have the 
tendency to crash every second or so :) This is a temporarily solution 
as I really want the original pthread solution in place for thread 
handling. For the time being this also means that OpenCL is disabled, 
due to the openCL device selection was also included in the pthread 

Lukas did some great work on nodegroups and fixing some in the 
data-structure of nodes related to the deprecation of node stacks values.

I would like to propose to meet on Tuesday 20:00 Amsterdam time to 
explain the compositor internals and node migrations. We meet at 
blendercoders and see if we need a new channel or not.

your local time of this event:
