@cindex Emacs 24, new features in
@itemize
@cindex packages, installing more
@item
Emacs now includes a package manager. Type @kbd{M-x list-packages} to
get started. You can use this to download and automatically install
many more Lisp packages.
@cindex lexical binding
@item
Emacs Lisp now supports lexical binding on a per-file basis. In
@emph{lexical binding}, variable references must be located textually
within the binding construct. This contrasts with @emph{dynamic
binding}, where programs can refer to variables defined outside their
local textual scope. A Lisp file can use a local variable setting of
@code{lexical-binding: t} to indicate that the contents should be
interpreted using lexical binding. See the Emacs Lisp Reference
Manual for more details.
@cindex bidirectional display
@cindex right-to-left languages
@item
Some human languages, such as English, are written from left to right.
Others, such as Arabic, are written from right to left. Emacs now has
support for any mixture of these forms---this is ``bidirectional text''.
@item
Handling of text selections has been improved, and now integrates
better with external clipboards.
@cindex themes
@item
A new command @kbd{customize-themes} allows you to easily change the
appearance of your Emacs.
@item
Emacs can be compiled with the Gtk+ 3 toolkit.
@item
Support for several new external libraries can be included at compile
time:
@itemize
@item
``Security-Enhanced Linux'' (SELinux) is a Linux kernel feature that
provides more sophisticated file access controls than ordinary
``Unix-style'' file permissions.
@item
The ImageMagick display library. This allows you to display many more
image format in Emacs, as well as carry out transformations such as
rotations.
@item
The GnuTLS library for secure network communications. Emacs uses this
transparently for email if your mail server supports it.
@item
The libxml2 library for parsing XML structures.
@end itemize
@item
Much more flexibility in the handling of windows and buffer display.
@end itemize

Your first port of call should be the @kbd{M-x list-packages} command.
This connects to the @uref{http:///elpa.gnu.org, GNU ELPA} (``Emacs
Lisp Package Archive'') server and fetches the list of additional
packages that it offers. These are GNU packages that are available
for use with Emacs, but are distributed separately. Select a package
to get more details about the features that it offers, and then if you
wish, Emacs can download and automatically install it for you.
