This file is about changes in Emacs version 27.
|
||
|
||
See file HISTORY for a list of GNU Emacs versions and release dates.
|
||
See files NEWS.26, NEWS.25, ..., NEWS.18, and NEWS.1-17 for changes
|
||
in older Emacs versions.
|
||
|
||
You can narrow news to a specific version by calling 'view-emacs-news'
|
||
with a prefix argument or by typing C-u C-h C-n.
|
||
|
||
Temporary note:
|
||
+++ indicates that all necessary documentation updates are complete.
|
||
(This means all relevant manuals in doc/ AND lisp doc-strings.)
|
||
--- means no change in the manuals is needed.
|
||
When you add a new item, use the appropriate mark if you are sure it applies,

* Installation Changes in Emacs 27.1
|

|

* Startup Changes in Emacs 27.1
|

|
||
|
||
* Changes in Emacs 27.1
|
||
|
||
---
|
||
** The new option 'tooltip-resize-echo-area' avoids truncating tooltip text
|
||
on GUI frames when tooltips are displayed in the echo area. Instead,
|
||
it resizes the echo area as needed to accommodate the full tool-tip
|
||
text.
|
||
|
||
+++
|
||
** New function 'logcount' calculates an integer's Hamming weight.
|
||
|
||
|
||
* Editing Changes in Emacs 27.1
|
||
|
||
---
|
||
** New variable 'x-wait-for-event-timeout'.
|
||
This controls how long Emacs will wait for updates to the graphical
|
||
state to take effect (making a frame visible, for example).
|
||
|
||
+++
|
||
** The new user option 'electric-quote-replace-double' controls
|
||
whether '"' is also replaced in 'electric-quote-mode'. If non-nil,
|
||
'"' is replaced by a double typographic quote.
|
||
|
||
|
||
* Changes in Specialized Modes and Packages in Emacs 27.1
|
||
|
||
** Dired
|
||
|
||
+++
|
||
*** The new user option 'dired-create-destination-dirs' controls whether
|
||
'dired-do-copy' and 'dired-rename-file' should create non-existent
|
||
directories in the destination.
|
||
|
||
** Ibuffer
|
||
|
||
---
|
||
*** New filter ibuffer-filter-by-process; bound to '/E'.
|
||
|
||
** Edebug
|
||
|
||
+++
|
||
*** The runtime behavior of Edebug's instrumentation can be changed
|
||
using the new variables 'edebug-behavior-alist',
|
||
'edebug-after-instrumentation-function' and
|
||
'edebug-new-definition-function'. Edebug's behavior can be changed
|
||
globally or for individual definitions.
|
||
|
||
** Enhanced xterm support
|
||
|
||
*** New variable 'xterm-set-window-title' controls whether Emacs sets
|
||
the XTerm window title. This feature is experimental and is disabled
|
||
by default.
|
||
|
||
** Gamegrid
|
||
|
||
---
|
||
*** Gamegrid now determines its default glyph size based on display
|
||
dimensions, instead of always using 16 pixels. As a result, Tetris,
|
||
Snake and Pong are more playable on HiDPI displays.
|
||
|
||
|
||
* New Modes and Packages in Emacs 27.1
|
||
|
||
|
||
* Incompatible Lisp Changes in Emacs 27.1
|
||
|
||
** The FILENAME argument to 'file-name-base' is now mandatory and no
|
||
longer defaults to 'buffer-file-name'.
|
||
|
||
---
|
||
** The function 'eldoc-message' now accepts a single argument.
|
||
Programs that called it with multiple arguments before should pass
|
||
them through 'format' first. Even that is discouraged: for ElDoc
|
||
support, you should set 'eldoc-documentation-function' instead of
|
||
calling 'eldoc-message' directly.
|
||
|
||
|
||
* Lisp Changes in Emacs 27.1
|
||
|
||
---
|
||
** The 'file-system-info' function is now available on all platforms.
|
||
instead of just Microsoft platforms. This fixes a 'get-free-disk-space'
|
||
bug on OS X 10.8 and later (Bug#28639).
|
||
|
||
---
|
||
** The function 'get-free-disk-space' returns now a non-nil value for
|
||
remote systems, which support this check.
|
||
|
||
|
||
* Changes in Emacs 27.1 on Non-Free Operating Systems
