The update was a couple of weeks ago now (i believe). The thread title had a notice in it RE mandatory update & the top of the main thread had big red letters for a ~week stating there was a mandatory update, then i left a smaller notice for a little while after but it has recently been removed. We also noted pools that hadn't updated, removed them from the pools list and re notified pool admins we could get hold of. Please update

I think you should reconsider keeping notice of a hard fork in the OP indefinitely. In this case the client would have continued working, and those who weren't mining would have been trying to transact, blissfully unaware that there had been a fork. It's not reasonable to expect people to sift through 250 pages of this thread "just in case"
Fair point, there is nothing about it on the first post any more. At least a wallet version number or date would have helped you.

Dev, maybe you could make this the first altcoin wallet that can detect when a new version is available?
