Hello, Arnaud
My system's age is about a week old, updated to tag=RELENG_8.
I've csup'ed yesterday, but I didn't noticed any changes related, did I 
miss something important? Anyway I'll do the upgrade this weekend maybe. 
Is  there any point to move to RELENG_9? I don't want to mess with the 
9'th changes for a little bit while.
