*** 'derived-mode-p' now takes the list of modes as a single argument.
The same holds for 'provided-mode-derived-p'.
The old calling convention where multiple modes are passed as
separate arguments is deprecated.

*** New functions to access the graph of major modes.
While 'define-derived-mode' still only supports single inheritance,
modes can declare additional parents (for tests like 'derived-mode-p')

** XLFDs are no longer restricted to 255 characters.
'font-xlfd-name' now returns an XLFD even if it is greater than 255
characters in length, provided that the LONG_XLFDs argument is true.

Other features in Emacs which employ XLFDs have been modified to
produce and understand XLFDs larger than 255 characters.
** New macro 'static-if' for conditional evaluation of code.
This macro hides a form from the evaluator or byte-compiler based on a
compile-time condition. This is handy for avoiding byte-compilation
