  <H2><A NAME="1"></A>1. XFree86 and X11R6.3</H2>
<p>XFree86 releases starting with the 3.2A beta are based on the
X Consortium's X11R6.3 (the final release from the X Consortium).</p>
<p>R6.3 is an update to R6.1, and is intended to be compatible with R6.1
and R6 at the source and protocol levels.  Binaries should be
upward-compatible.  X11R6.3 includes some new Xserver extensions:
SECURITY, XC-APPGROUP, XpExtension (print extension), and an updated,
and standardised version of LBX.  X11R6.3 also has new standards,
including RX (X Remote Execution MIME type), and a proxy management
protocol.  X11R6.3 includes support for gzipped fonts.</p>
<p>R6.1 is an update to R6,
and is intended to be compatible with R6 at the source and protocol
levels.  Binaries should be upward-compatible.  X11R6.1 includes some
new Xserver extensions: DOUBLE-BUFFER, XKEYBOARD and RECORD.</p>
<p>What about R6.2?  X11R6.2 is the name given to a subset of X11R6.3,
which has only the print extension and the Xlib implementation of
vertical writing and user-defined character support in addition to
those features included in R6.1.</p>
