V0.800 from http://people.debian.org/~psg/elisp/font-latex.el ?

It's not obsolete.

No, it means "You've got Mail".

Are you using Emacs' latex-mode or AUC-TeX?

If AUC-TeX, this version of font-latex.el is tailored to work with the
development version of AUC-TeX.  If you are using it with AUC-TeX
version 10.0g or less, you will need to insert this code near the end of
the font-latex.el file:

 (add-hook 'LaTeX-mode-hook 'font-latex-setup)

To know if you are actually using font-latex, look at the variable
font-lock-defaults while in latex-mode.  You should see mention of
"font-latex-keywords font-latex-keywords-1 font-latex-keywords-2" in the
result.
