autoloads have been redefined as functions).

|

** The function `current-time' now returns extended-format time stamps
|
||||
(HIGH LOW USEC PSEC) that use picosecond resolution; the PSEC
|
||||
component is new. PSEC is typically a multiple of 1000 on current

machines. Other functions that use this format, such as

file-attributes and format-time-string, have been changed accordingly.

Old-format time stamps are still accepted.

or expression to evaluate.
|

** Face underlining can now use a wave.

See the "Face Attributes" section of the Elisp manual.

|

** New fringe bitmap exclamation-mark.
|
||||
** In the Package Menu, newly-available packages are listed as "new",

** String values for `initial-buffer-choice' also apply to emacsclient
|

frames, if emacsclient is only told to open a new frame without

specifying any file to visit or expression to evaluate.
|

** `C-x C-q' is now bound to the new minor mode `read-only-mode'.
|

This minor mode replaces `toggle-read-only', which is now obsolete.

** Emacs now generates backtraces on fatal errors.

** You can prevent the creation of lock files by setting `create-lockfiles'
|

to nil. Use with caution, and only if you really need to.
|
||||
** New variable `create-lockfiles' specifies usage of lockfiles.
|

It defaults to t. Changing it to nil inhibits the creation of lock
|
||||
files (use this with caution).

** Using "unibyte: t" in Lisp source files is obsolete.
|

Use "coding: raw-text" instead.

||||
`ucs-insert' is now an obsolete alias for `insert-char'.

|
||||
** The `z' key no longer has a binding in most special modes.
|
||||
It used to be bound to `kill-this-buffer', but `z' is too easy to
|
||||
accidentally type.
|
||||
|
||||
** New option `yank-handled-properties' allows processing of text
|
||||
properties on yanked text, in more ways that are more general than
|
||||
just removing them, as done by `yank-excluded-properties'.

M-x delete-trailing-whitespace should delete trailing lines at the end
|

of the buffer. It defaults to t.

||||
|
||||
** New option `delete-trailing-lines' specifies whether the M-x
|
||||
delete-trailing-whitespace command should delete trailing lines at the
|

** Search and Replace changes

||||

||||
+++
|
||||
** `C-x r +' is now overloaded to invoke `append-to-register.
|
||||
*** Non-regexp Isearch now performs "lax" space matching.
|
||||
Each sequence of spaces in the supplied search string may match any
|
||||
sequence of one or more whitespace characters, as specified by the
|
||||
variable `search-whitespace-regexp'. (This variable is also used by a
|
||||
similar existing feature for regexp Isearch).
|
||||
|
||||
+++
|
||||
** New option `register-separator' specifies the register containing
|
||||
the text to put between collected texts for use with M-x
|
||||
append-to-register and M-x prepend-to-register.
|
||||
*** New Isearch command `M-s SPC' toggles lax space matching.
|
||||
This applies to both ordinary and regexp Isearch.
|
||||
|
||||
** Search changes
|
||||
*** New option `replace-lax-whitespace'.
|
||||
If non-nil, `query-replace' uses flexible whitespace matching too.
|
||||
The default is nil.
|
||||
|
||||
*** Global `M-s _' starts a symbol (identifier) incremental search,
|
||||
and `M-s _' in Isearch toggles symbol search mode.
|
||||
`M-s c' in Isearch toggles search case-sensitivity.
|
||||
|
||||
*** `M-s SPC' in Isearch toggles whitespace matching mode
|
||||
in both ordinary and regexp incremental search, so that each
|
||||
sequence of spaces in the search string matches any combination
|
||||
of one or more whitespace characters defined by the variable
|
||||
`search-whitespace-regexp'. In ordinary incremental search,
|
||||
`isearch-toggle-lax-whitespace' toggles the value of the variable
|
||||
`isearch-lax-whitespace'. In regexp incremental search, it toggles
|
||||
the value of the variable `isearch-regexp-lax-whitespace'.

|
||||
** query-replace changes
|
||||
** `C-u M-=' now counts lines/words/characters in the entire buffer.
|
||||
|
||||
*** When new option `replace-lax-whitespace' is non-nil,
|
||||
and you enter a space or spaces in the strings or regexps
|
||||
to be replaced, `query-replace' will match any sequence matched
|
||||
by the regexp `search-whitespace-regexp'.
|
||||
** New binding `M-g c' for `goto-char'.
|
||||
|
||||
** M-x move-to-column, if called interactively with no prefix arg, now
|
||||
prompts for a column number.
|
||||
|
||||
** `mouse-avoidance-banish-position' can now be used to customize
|
||||
`mouse-avoidance-mode' further.
|
||||
|
||||
** `C-u M-=' now counts lines/words/characters in the entire buffer.
|
||||
|
||||
** `C-M-f' and `C-M-b' will now move to the path name separator
|
||||
character when doing minibuffer filename prompts.
|
||||
|
||||
** `goto-char' is now bound to `M-g c'.
|
||||

||||
see the `apropos' Custom group for details.
|
||||
|
||||
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 customize how are displayed the

ANSI terminal colors and styles by customizing the corresponding

`term-color-<COLOR>', `term-color-underline' and `term-color-bold'
|

faces.

This package has been rewritten to use Tabulated List mode.

Customize cal-html-holidays to change this.

** CL
|

*** CL's main entry is now (require 'cl-lib).

these commands now).

*** The minibuffer default for `=' (`dired-diff) has changed.

It is now the backup file for the file at point, if one exists.
|
||||
In Transient Mark mode the default is the file at the active mark.
