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.

This version finally gets rid of all 8-bit coding issues, and supports UTF-8 and other multi-byte input. All known GhostScript versions should work for PostScript and PDF in SAFER mode. Redesigned icons now come in several sizes, blending better with the text. Installation has been made more flexible and robust, more conservative in its choices, and the Lisp startup file will now be installed automatically. It is strongly recommended that you remove a previous installation before installing this version to avoid keeping conflicting or unnecessary files.
