4.5 What is different about Emacs 25?
Emacs can now embed native widgets inside Emacs buffers, if you have
gtk3 and webkitgtk3 installed. E.g., to access the embedded webkit
browser widget, type M-x xwidget-webkit-browse-url.
Emacs can now dynamically load external modules compiled as shared
C-x 8 has new shorthands for several popular characters, type
C-x 8 C-h to list shorthands.
A new minor mode
global-eldoc-mode is enabled by default, and
shows in the echo area or in the mode line the argument list of the
Emacs Lisp form at point.
On text terminals that support the “bracketed paste mode” EMacs now
uses that mode by default. This mode allows Emacs to distinguish
between pasted text and text typed by the user.
Emacs 25 comes with data files imported from the latest Unicode
Standard version 9.0.0.
The support for bidirectional editing was updated to include all the
features mandated by the latest Unicode Standard version 9.0.0.
Search command can now perform character folding in matches. This is
analogous to case folding, but instead of disregarding case variants,
it disregards wider classes of distinctions between similar
characters, such as matching different variants of double quote
characters, ignoring diacritics, etc.
The Emacs Web Browser EWW was extended to render text using
variable-pitch fonts, and got other new features.
Rmail can now render HTML mail messages, if Emacs is built with
libxml2 or if you have the Lynx browser installed.
VC now has basic support for
push commands, implemented for
Bzr, Git, and Hg.
Hide-IfDef mode now support full C/C++ expressions in macros,
macro argument expansion, interactive macro evaluation and automatic
New package Xref replaces Etags’s front-end and UI. Xref provides a
generic framework and new commands to find and move to definitions of
functions, macros, data structures etc., as well as go back to the
location where you were before moving to a definition. It supersedes
and obsoletes many Etags commands, while still using the etags.el code
that reads the TAGS tables as one of its back-ends. As result, the
popular key bindings M-. and M-, have been changed to
invoke Xref commands.
The new package Project provides generic infrastructure for dealing
Emacs can now draw horizontal scroll bars on some platforms that
provide toolkit scroll bars, namely Gtk+, Lucid, Motif and Windows.
