 <ol>
-  <li>LLVM now includes a Just-In-Time compiler for the PowerPC target.</li>
-  <li>llvmgcc and llvmg++ now emit source line number information when '-g' is
-  passed in, making it possible to map from LLVM code back to source.
-  This information is currently used by llvm-db and can be used with other 
-  tools and passes.</li>
-  <li>The test/Programs hierarchy <a href="http://llvm.cs.uiuc.edu/PR257">has
-    been moved out of the main LLVM tree</a> into a separate CVS repository and
-    tarball. This shrinks the distribution size of LLVM itself significantly.
-  </li>
-  <li>LLVM now optimizes global variables more aggressively than it did 
-  before.</li>
-  <li>LLVM now includes the new '<tt>undef</tt>' value and 
-  <a href="LangRef.html#i_unreachable"><tt>unreachable</tt></a> instruction,
-  which give the optimizer more information about the behavior of the
-  program.
-  </li>
-  <li>Bytecode compression with bzip2 has been implemented. All bytecode files
-  generated by LLVM will now be compressed by default. Compression can be 
-  disabled with the <tt>-disable-compression</tt> option to the tools that can 
-  generate bytecode files.
-  </li>
-  <li>A generic <a href="CommandGuide/html/llvmc.html">compiler driver</a>
-  (llvmc) and
-  an associated <a href="CommandGuide/html/llvm-ld.html">generic linker</a>
-  (llvm-ld) have been added. The compiler driver is generic because it can be
-  configured
-  to pre-process, translate, optimize, assemble, and link code from any source
-  language with an LLVM front-end. This makes it easier for compiler writers
-  to hide the multiple steps required to compile a program (compiling,
-  optimizing, linking runtime libraries, etc) in one simple command.
-  </li>
-  <li>The <a href="http://llvm.cs.uiuc.edu/PR263">dependent libraries</a> 
-  feature has been implemented. This allows front end compilers to indicate in
-  the bytecode which libraries the bytecode needs to be linked with. Both the
-  C/C++ and Stacker front ends support generating the required dependencies. 
-  The linker now supports using this information to ensure required libaries are
-  linked into the module. This minimizes the need to use the <tt>-l</tt> option
-  when using <a href="CommandGuide/html/llvmc.html"><tt>llvmc</tt></a>.
-  </li>
-  <li>The LLVM makefiles have been improved to build LLVM much faster and 
-  includes new targets (like dist-check, uninstall). One important user-visible
-  change is that libraries and tools will now be built into 
-  <tt>$builddir/Debug/{bin,lib}</tt>
-  instead of <tt>$builddir/tools/Debug</tt> and <tt>$builddir/lib/Debug</tt>
-  (Similarly for <tt>Release</tt> and <tt>Profile</tt> builds).
-  </li>
-  <li>The LLVM source code is much more compatible with Microsoft Visual C++,
-  including the JIT and runtime-code generation, though the entire system 
-  may not work with it.
-  </li>
-  <li>The JIT-Target interfaces <a href="http://llvm.cs.uiuc.edu/PR283">are 
-    now much simpler</a> and more powerful.
-  </li>
-  <li>LLVM now provides llvm-ar and llvm-ranlib tools for working with archives
-      of LLVM bytecode files.</li>
-  <li>zlib and libpng are <a href="http://llvm.cs.uiuc.edu/PR417">no longer
-      included in the main LLVM tarball</a>.</li>
-  <li>The LLVM code generator now automatically generates assembly code writers
-      from an abstract target descriptions, eliminating the need to write
-      assembly printers manually.</li>
-  <li>LLVM regression and feature tests now use DejaGNU instead of QMTest.</li>
