its really annoying
(if all mods will write about new version)

Yeah... Nup. We only nag about the latest version of BOP for that particular version of Minecraft and i think that is absolutely appropriate. We've had to deal with people reporting bugs in the past that are no longer valid simply because they are using an old version of BOP and are unaware of it. That's not something we have any intention of allowing anymore and if people disable the update nagging, they'll still think they have the right to complain to us about a bug we've already fixed in an update.
