Recently the LATEX package has been updated by the LATEX3 team, led by Frank Mittelbach, to include some long-requested improvements and to reunify all the patched versions which have cropped up since the release of LATEX 2.09 some years ago. To distinguish the new version from the old, it is called LATEX2e. This documentation deals with LATEX2e.
LATEX is pronounced ``Lay-tech'' or ``Lah-tech.'' If you refer to LATEX in an ASCII environment you type LaTeX. LATEX2e is pronounced ``Lay-tech two e'' and typed LaTeX2e.
