There's no official news and/or announcement that 66 has already replaced s6 on Obarun and new installations should exclusively use the new repos as mentioned by yourself. The news about new mirrors does not explicitly state any of this and in return will cause confusion or may be ignored by new users. You actually even state that "The old repositories stays operational for compatibility reason" which I cannot test true. A minimal install fails to be operational.
s6opts was not officially replaced by 66. Did you see any news on the home concerning the transition? You are aware about the incoming transition because you follow this forum frequently. Even when you will see the explanation to pass to 66, the transition will be not complete because i will let the time to user to pass to 66 (no pressure here) surely 3 mounths. When this period will done than Obarun will be officially under 66 not before.
There's no official ISO release yet. Whoever reads the forums knows you are working on it, other people don't.
you're right, so

You cannot expect people to roam forums to find this or similar discussions
to be honest with you, i don't care for the moment about new user, my priority is current user, some "guys" are here from the starts of Obarun(mostly 4years) and i will not break their system because new users want to test Obarun.
Remove faulty ISOs and announce that there will be no ISOs for a week or so
People are downloading old version even if a fresh one, what should i do? removing all archived ISO? the prevent message that i did should be sufficient for now.
I understand that you can be impatient. All rock user of Obarun wait for the change but also wait for a new page to turn officially onto it. Just they are here and wait.
Old users lived transition between runit and s6 and know.
Obarun have a very small community of users, but those users have a big knowledge and skill on linux system :). Obarun do not take a big place in the world linux community. Many person considers Obarun as an useless spin of Arch, complicated to install because we don't provide a gtkbox to answer yes,complicated to use because they can have their F@ # @ dependencies on libsystem:D dummy etc etc. But you know what, that's good for me, i prefer skilled users :p. Don't get me wrong, all person are welcomed here even beginner people but that mean that those guys needs to help themself first(read doc, studding, make mistake, start from zero again and again), this is the best manner to learn and they will always found someone here to help.
Note: i still waiting for your answer about my mail ;)
