Since upgrading to emacs 26.1 (because emacs 25 has problems with pegging the cpu on mac), I get some weird problems with slime.      Is anyone else using slime with emacs 26.1?

Here is an example problem I have.

Debugger entered--Lisp error: (void-function slime-changelog-date)

  slime-changelog-date()

  slime-startup-message()

  slime-repl-update-banner()

  slime-init-output-buffer(#<process SLIME Lisp>)

  slime-repl-connected-hook-function()

  run-hooks(slime-connected-hook)

  slime-set-connection-info( ... stuff deleted ....)

But when I look in the function slime-startup-message, there is no mention of slime-changelog-date.

(defun slime-startup-message ()

  (when slime-header-line-p

    (setq header-line-format 

          (format "%s  Port: %s  Pid: %s"

                  (slime-lisp-implementation-type)

                  (slime-connection-port (slime-connection))

                  (slime-pid))))

  (when (zerop (buffer-size))

    (let ((welcome (concat "; SLIME " slime-version)))

      (if slime-startup-animation

          (animate-string welcome 0 0) 

        (insert welcome)))))
