* Changes in Specialized Modes and Packages in Emacs 24.2
** Term changes
The variables `term-default-fg-color' and `term-default-bg-color' are
now deprecated in favor of the `term-face' face, that you can
customize. Also, it is now possible to cutomize how are displayed the
ANSI terminal colors and styles by cutomizing the corresponding
`term-color-<COLOR>', `term-color-underline' and `term-color-bold'
faces.
** CL's main entry is now (require 'cl-lib).
`cl-lib' is like the old `cl' except that it uses the namespace cleanly,
i.e. all its definitions have the "cl-" prefix.
