Undocumented emacs version ?

["John D. Coleman" <jdc843@sccoast.net>]

http://www.gnu.org/software/emacs/emacs.html states in part :
Latest stable release: 21.3 (March 24, 2003)

but ftp://ftp.gnu.org/gnu/emacs/ has a 21.4 version

Is the version stated on the webpage outdated or is 21.4 a development  
version ?

If outdated - then update webpage please.
If development - include 'alpha/beta/unstable' in 21.4's package name  
please. Or note on webpage though that would double the workload.

You need a README file in the ftp directory. Partly to explain  
what .xdelta and .diff files are. Used with program : 'patch' ?

I read elib.README which explained what elib is. But there isn't one  
for leim.

My 2 cents.
