How do you guys update SLIME?
It seems to me that since slime-changelog-date is a defvar, it doesn't change when reloading (or re-evaluating) slime.el. So when the protocol changes, emacs still thinks it speaks the old version.
Do you actually *gasp* quit your XEmacs or Emacs from time to time?

PS: oh, the irony. As I was writing the first incarnation of this E-mail, I have inserted the USB clipdrive which hosts my GPG key. That caused the machine to freeze instantly. USB in Linux is decidedly the crappiest piece of software that I have to live with.
