Hi,
I realize that I started QA_3_4 too soon. It only needs to begin when 3.4.0 (final) is released. I'll remove it.
From now on we should focus on stabilizing MAINT_3_4_0; new features
would go to master only.
If it makes sense to fix a bug in QA_3_3 (for 3.3.9) we do it; then we merge to MAINT_3_4_0 and master.
