The purpose of the preview-latex package is to
embed LaTeX environments such as display math or
figures into Emacs source buffers. As of version
11.80, it has been integrated into AUCTeX and will
no longer be separately released.
Information regarding Project Releases and Project Resources. Note that the information here is a quote from Freecode.com page, and the downloads themselves may not be hosted on OSDN.
The installation procedure has been further improved so that
more configurations should now be detected automatically.
The encoding support of preview-latex has been refined so
that the run buffer will now yield readable output again in
most situations where it can be reasonably expected to do
so.
