NOTE: Be sure to start the talk by noting:

- Today: covering note-7-3, note-7-4, some of note-7-5
- There are many "THANKS" but I'll skip them verbally to save time.
- There are many items I'll skip over.
- Trend (I think): fewer new features; higher proportion of highly
  technical improvements and bug fixes.
- I'm only hitting some high points today (mostly not bug fixes, e.g.).
  Suggestion: browse the release notes.
- Feel free to ask questions -- it's OK if we don't get to the end,
  and besides, my practice talk took about 24 of the 30 allotted
  minutes.

Here's how I highlighted sections.

(require 'enriched)

  (interactive "P")
  (facemenu-set-foreground (cond ((equal p 0) "darkcyan")
                                 (p "black")
                                 (t "red3"))
                           (if mark-active
                               (region-beginning))
                           (if mark-active
                               (region-end))))
