10.2.6 Emacsen

Gnus should work on :

• Emacs 20.7 and up.

• XEmacs 21.1 and up.

This Gnus version will absolutely not work on any Emacsen older than that. Not reliably, at least. Older versions of Gnus may work on older Emacs versions.

There are some vague differences between Gnus on the various platforms--XEmacs features more graphics (a logo and a toolbar)---but other than that, things should look pretty much the same under all Emacsen.
