4.3 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
libraries.
• ‘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
scanning of ‘#define’d symbols.
• 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
with projects.
• Emacs can now draw horizontal scroll bars on some platforms that
provide toolkit scroll bars, namely Gtk+, Lucid, Motif and Windows.
