Does Richard M. Stallman still scrutinize and develop the codes of Emacs now?

[Hongyi Zhao]

I noticed that the following statement from the AUTHORS file of Emacs:

;;;
Richard M. Stallman: wrote [The original GNU Emacs and numerous files]
  easymenu.el image-mode.el menu-bar.el paren.el
and co-wrote cc-align.el cc-cmds.el cc-defs.el cc-engine.el cc-langs.el
  cc-menus.el cc-mode.el cc-styles.el cc-vars.el font-lock.el
and changed files.el keyboard.c simple.el xterm.c xdisp.c rmail.el
  fileio.c process.c sysdep.c buffer.c xfns.c window.c subr.el
  configure.ac startup.el sendmail.el emacs.c Makefile.in editfns.c
  info.el dired.el and 1338 other files
;;;

But I've never seen him on Emacs relevant mailing lists. Does Richard
M. Stallman still scrutinize and develop the codes of Emacs now?
