+** Running in a console window in Windows now uses the console size.
+
+Previous versions of Emacs erred on the side of having a usable Emacs
+through telnet, even though that was inconvenient if you use Emacs in
+a local console window with a scrollback buffer. The default value of
+w32-use-full-screen-buffer is now nil, which favours local console
+windows. Recent versions of Windows telnet also work well with this
+setting. If you are using an older telnet server then Emacs detects
+that the console window dimensions that are reported are not sane, and
+defaults to 80x25. If you use such a telnet server regularly at a size
+other than 80x25, you can still manually set
+w32-use-full-screen-buffer to t.
