But since these bugs are flagged to be (also) in 4.3 branch, does it mean 4.3 branch is not maintained any more (although last 4.3.6 release was on 2011-06-27)? Or Is it that fixes are not always applied on previous branches ? Are there some fixes applied in 4.5/4.6 which are not applied to 4.4 ? So what is "right" branch to use so for my backend port ? Again, thank you for your help! Aurélien
