+<p>
+This is the third public release of the LLVM compiler infrastructure.  This
+release incorporates several <a href="#newfeatures">new features</a> (including
+exception handling support for the native code generators, the start of a
+source-level debugger, and profile guided optimizer components), many <a
+href="#qualityofimp">speedups</a> and <a href="#codequality">code quality</a>
+improvements, documentation improvements, and a small collection of important <a
+href="bugfix">bug fixes</a>.  Overall, this is our highest quality release to
+date, and we encourage you to upgrade if you are using LLVM 1.0 or 1.1.

+<p><B> FIXME: UPDATE: </b>
+At this time, LLVM is known to correctly compile and run all C
 & C++ SPEC CPU2000 benchmarks, the Olden benchmarks, and the Ptrdist
 benchmarks.  It has also been used to compile <b>many</b> other programs.  LLVM
 now also works with a broad variety of C++ programs, though it has still
 received less testing than the C front-end.
