+<p>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 much less testing than the C front-end.
-</p>
-
-<p>
-The LLVM native code generators are very stable but do not currently support
-unwinding (exception throwing or <tt>longjmp</tt>ing), which prevent them from
-working with programs like the <tt>253.perlbmk</tt> in SPEC CPU2000. The C
-backend and the rest of LLVM supports these programs, so you can
-still use LLVM with them. Support for unwinding will be added in a future
-release.

-In this release, the following build problems were fixed:
+LLVM gained several improvements to its build and installation
+infrastructure in this release. There is now
+a <tt>autoconf/AutoRegen.sh</tt> script that you can run to rebuild the
+<tt>configure</tt> script and its associated files
+(<a href="http://llvm.cs.uiuc.edu/PR105">Bug 105</a>) as well as beta support
+for "make install" (<a href="http://llvm.cs.uiuc.edu/PR208">Bug 208</a> and
+<a href="http://llvm.cs.uiuc.edu/PR220">Bug 220</a>) and RPM package generation
+(<a href="http://llvm.cs.uiuc.edu/PR203">Bug 203</a>).
