Just finished upgrading WordPress to 1.5.2 from 1.5 and I have to say… I must love pain. I’m sure it’d be a breeze if I didn’t have much, or any, customization. But, as you may be able to tell, I have a Freakin’ Load(tm) of them. No customizations: upgrade in 5 minutes. With all of mine (all plugins; no personally coded hacks): no less than 3-4 hours.
And, as you may also notice, the hover text that says how long ago things were posted (under the Recent Activity sidebar) is a wee-bit broken. Once you get past the first 3 or 4 items it gets sane again. I don’t feel like debugging it. :P As it is, I’m amazed I managed to get as much working as I did.
