I have run my first round of soak and performance tests on what is now in the 2.x branch. Good news is the code looks stable. Not so good news is it appears that GKOP performance has taken a material hit vs 2.11 and earlier versions. I need to confirm this via more targeted tests and if it turns out not to be real, figure out what is causing it. Hopefully I will get to this done in the next few days.
