-<p>This is the second public release of the LLVM compiler infrastructure. This
-release is primarily a bugfix release, dramatically improving the C/C++

-better interoperability with external source bases, a new example language

-LLVM profiler, similar to gprof</a> is available</li>

-<li>LLVM and the C/C++ front-end now compile on Mac OS/X! Mac OS/X users can
-now explore the LLVM optimizer with the C backend and interpreter. Note that
-LLVM requires GCC 3.3 on Mac OS/X.</li>
-
-<li>LLVM has been <a
-href="http://mail.cs.uiuc.edu/pipermail/llvmdev/2003-November/000554.html">moved
-into an 'llvm' C++ namespace</a>, for easier integration with third-party
-code. Note that due to lack of namespace support in GDB 5.x, you will probably
-want to upgrade to GDB 6 or better to debug LLVM code.</li>
-
-<li>
-The build system now copies Makefiles dynamically from the source tree to the
-object tree as subdirectories are built. This means that:
- <ol>
- <li>
- New directories can be added to the source tree, and the build will
- automatically pick them up (i.e. no need to re-run <tt>configure</tt>).
- </li>
-
- <li>
- You will need to build LLVM from the top of the object tree once to ensure
- that all of the Makefiles are copied into the object tree subdirectories.

-
-<li>A front-end for "Stacker" (a simple Forth-like language) is now
- <a href="http://llvm.cs.uiuc.edu/PR136">included in the main LLVM tree</a>.
- Additionally, Reid Spencer, the author, contributed a document <a href="Stacker.html">describing his experiences writing Stacker, and the language itself</a>. This document is invaluable for others writing front-ends targetting LLVM.</li>
-
-<li>The <tt>configure</tt> script will now configure all projects placed in the
-<tt>llvm/projects</tt> directory.</li>
-
-<li>The <tt>-tailcallelim</tt> pass can now introduce "accumulator" variables
- to transform functions in many common cases that it could not before.</li>
-
-<li>The <tt>-licm</tt> pass can now sink instructions out the bottom of loops
-in addition to being able to hoist them out the top.</li>

-to be <a href="http://llvm.cs.uiuc.edu/PR86">significantly more
-precise</a>.</li>

-<li>LLVM 1.1 implements a simple size optimization for LLVM bytecode files.
- This means that the 1.1 files are smaller than 1.0, but that 1.0 won't
- read 1.1 bytecode files.</li>
