-<p>LLVM 2.1 brings two new beta C front-ends.  First, a new version of llvm-gcc
-based on GCC 4.2, innovatively called "llvm-gcc-4.2".  This promises to bring
-FORTRAN and Ada support to LLVM as well as features like atomic builtins and
-OpenMP.  None of these actually work yet, but don't let that stop you checking
-it out!</p>
+<p>LLVM 2.2 fully supports both the llvm-gcc 4.0 and llvm-gcc 4.2 front-ends (in
+LLVM 2.1, llvm-gcc 4.2 was beta).  Since LLVM 2.1, the llvm-gcc 4.2 front-end
+has made leaps and bounds and is now at least as good as 4.0 in virtually every
+area, and is better in several areas (for example, exception handling
+correctness).  We strongly recommend that you migrate from llvm-gcc 4.0 to
+llvm-gcc 4.2 in this release cycle because <b>LLVM 2.2 is the last release
+that will support llvm-gcc 4.0</b>:  LLVM 2.3 will only support the llvm-gcc
+4.2 front-end.</p>
 
-<p>Second, LLVM now includes its own native C and Objective-C front-end (C++ is
-in progress, but is not very far along) code named "<a
-href="http://clang.llvm.org/">clang</a>".  This front-end has a number of great
-features, primarily aimed at source-level analysis and speeding up compile-time.
-At this point though, the LLVM Code Generator component is still very early in
-development, so it's mostly useful for people looking to build source-level
-analysis tools or source-to-source translators.</p>
+<p>The <a href="http://clang.llvm.org/">clang project</a> is an effort
+to build a set of new front-end technology for the LLVM optimizer and code
+generator.  Currently, its C and Objective-C support is maturing nicely, and it
+has advanced source-to-source analysis and transformation capabilities.  If you
+are interested in building source-level tools for C and Objective-C (and
+eventually C++), you should take a look.  However, note that clang is not an
+official part of the LLVM 2.2 release.  If you are interested in this project,
+please see the web site and check it out from SVN head.</p>
