* Changes in Specialized Modes and Packages in Emacs 22.1:
-** Makefile mode has now been split up into specialized modes for automake,
-gmake, makepp and BSD make. The former two couldn't be differentiated before,

Info pages show embedded images, in Emacs frames with image support.

There have been extensive changes "under the hood" which can affect
derived mode writers. Some of these changes are likely to cause
incompatibilities with existing derived modes, but on the other hand

happen when macros are involved.
