If hooks are going, whats the process to get my current ones working on the new version? I only use a few, online indicator, EZ scroll top and an adblock checker. Also I have quite big ratings application that I assume will break.
Also, you said ages ago you were going to prepare for removing display name login, there's been no sign of that. I still disagree with this entirely and can't see any benefit, I've not had a single hacking complaint in 19 years on my site.
