* Installation Changes in Emacs 21.1
+** There are two new resources for colormap handling under X.
+
+*** The X resource `visualClass, class `VisualClass', specifies the
+visual Emacs should use. The resource's value should be a string of
+the form `CLASS-DEPTH', where CLASS is the name of the visual class,
+and DEPTH is the requested color depth as a decimal number. Valid
+visual class names are
+
+ TrueColor
+ PseudoColor
+ DirectColor
+ StaticColor
+ GrayScale
+ StaticGray
+
+Visual class names specified as X resource are case-insensitive, i.e.
+`pseudocolor', `Pseudocolor' and `PseudoColor' all have the same
+meaning.
+
+The program `xdpyinfo' can be used to list the visual classes
+supported on your display, and which depths they have. If
+`visualClass' is not specified, Emacs uses the display's default
+visual.
+
+Example:
+
+ emacs.visualClass: TrueColor-8
+
+*** The X resource `privateColormap', class `PrivateColormap',
+specifies that Emacs should use a private colormap if it is using the
+default visual, and that visual is of class PseudoColor. Recognized
+resource values are `true' or `on'.
+
+Example:
+
+ emacs.privateColormap: true
+
** `movemail' defaults to supporting POP. You can turn this off using
the --without-pop configure option, should that be necessary.

+ default visual.
+
+ * xterm.h (select_visual): Change prototype.
+
+ * xfns.c (select_visual): Rewritten. Recognize user-specified
