** The default value of `comment-use-global-state' is changed to t,
and this variable has been marked obsolete.
** New user options:
*** `read-regexp-defaults-function' defines a function to read regexps,
used by commands like `rgrep', `lgrep' `occur', `highlight-regexp',
etc. You can customize this to specify a function that provides a
default value from the regexp last history element, or from the symbol
found at point.
*** `load-prefer-newer', affects how the `load' function chooses the
file to load. If this is non-nil, then when both .el and .elc
versions of a file exist, and the caller did not explicitly specify
which one to load, then the newer file is loaded. The default, nil,
means to always load the .elc file.

** CUA mode
*** CUA mode was changed to make use of delete-selection-mode and
shift-select-mode. So you can now enable it independently from
transient-mark-mode, delete-selection-mode, and shift-select-mode.
As a result, cua-highlight-region-shift-only is obsolete
(you can disable transient-mark-mode to get the same result).
*** CUA mode now uses `delete-selection-mode' and `shift-select-mode'.

** New variable `enable-dir-local-variables'.
Directory-local variables are ignored if this is set to nil. This may
be useful for modes that want to ignore directory-locals while still
respecting file-local variables.
** New functions `special-form-p' and `macrop'.
** New macro `define-alternatives' can be used to define generic commands.
Generic commands are interactive functions whose implementation can be
selected among several alternatives, as a matter of user preference.
** The `defalias-fset-function' property lets you catch `defalias'
calls, and redirect them to your own function, instead of `fset'.
** Docstrings can be made dynamic by adding a `dynamic-docstring-function'
text-property on the first char.

*** The separator for `completing-read-multiple' can now be a regexp.
The default separator has been changed to allow surrounding spaces

*** New option `read-regexp-defaults-function' defines the function
that provides the default value for commands that ask for a regexp:
`rgrep', `lgrep' `occur', `multi-occur', `multi-occur-in-matching-buffers',
`highlight-regexp', `highlight-lines-matching-regexp', `highlight-phrase'.
This option can be customized to values that provide a default value
from the regexp last history element or from the symbol found at point.
*** The `common-substring' arg of `display-completion-list' is obsolete.
Either use `completion-all-completions', which returns highlighted
strings (including for partial or substring completion), or call
`completion-hilit-commonality' to add the highlight.
** New option `load-prefer-newer', if non-nil, means that when both
.el and .elc versions of a file exist, rather than `load' always
choosing the .elc version, it will choose whichever is newer
