Release notes for version 0.7.8 of the preview-latex package:

preview-latex dresses up your LaTeX source by pasting judiciously
selected chunks (such as single formulas) chopped from unwieldy
preview pages right over their source in the Emacs/XEmacs buffer.  You
get to have your eye candy and edit it, too.  Since only the display
of the text is affected, you can safely test-drive on important
documents right away.  Quitting its use can be done anytime you'd want
to, which you won't.

The employed style file `preview.sty' is independently useful for
extraction of selected text elements as images.  The package is
released under the GNU Public License (GPL).  At the current point of
time, at least GNU Emacs-21.1 under the X window system, AUC TeX
(11.14 or later recommended, see below), a working LaTeX installation
and GhostScript are required.  This version also supports XEmacs-21,
best in version 21.4.9 or later, and the various Windows ports of
XEmacs.  You may also use recent CVS versions of Windows GNU Emacs.

Release 0.7.8 has gained a few more commands, its menu has been
reorganized, the `fleqn' document class option from LaTeX is fully
supported, `preview.sty' has gained a much more powerful interface for
configuring previews and a few more items are previewed by default or
more correctly.  Various bugs have been fixed and the installation
process does a better job of getting things to work particularly for
Windows users, with better documentation, too.  Whitespace changes
will not invalidate previews as they did before.  This means that
outline-minor-mode is usable in XEmacs now.

The `README' file provides adequate information for firing up
preinstalled distributions, and pointers how to provide feedback.  The
`INSTALL' file contains a special section with advice for package
providers.  There is also a file `INSTALL.windows' detailing
instructions for users of that operating system.

SourceForge project page that among others offers anonymous CVS access
is located at <URL:http://sourceforge.net/projects/preview-latex>.

Additional files can be found at
<URL:http://prdownloads.sourceforge.net/preview-latex>:

* If you don't have texinfo 4.0 or later installed, prebuilt
  documentation files can be found there.

* Tarballs of preview-latex for all users, alternatively RPMs for
  RedHat Linux.  For the binary RPMs, you will need the
  preview-latex-common RPM as well as the Emacs-flavor specific RPM.

* AUC TeX is now located at <URL:http://www.nongnu.org/auctex>.  The
  download area should also provide you with RPMs if you are using
  RedHat Linux.

The RPMs require a few packages that should be readily available in
current distributions.  RedHat 7.3 contains Emacs-21.2 and
GhostScript-6.52 which are about the minimum versions to be
recommended.  Later releases should work fine.  XEmacs in current
distributions will still be affected with a serious display bug, see
the PROBLEMS file or the respective manual section.
