Yeah, so I'm just going to NAK this until things are improved: NAKed-by: Ingo Molnar it's not like we are overly bored in timekeeping and need the extra complexity as much as possible. Proper, comprehensive, proactive technical description is needed, with proper changelogs, not just half-baked notes. If all that is fixed I'll lift my NAK. Thanks, Ingo
