 <p>In the LLVM 3.0 time-frame, the Clang team has made many improvements:</p>

+<ul>
+  <li>Greatly improved support for building C++ applications, with greater stability and better diagnostics.</li>
+  
+  <li><a href="http://clang.llvm.org/cxx_status.html">Improved support</a> for the <a href="http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=50372 ">C++ 2011</a> standard, including implementations of non-static data member initializers, alias templates, delegating constructors, the range-based for loop, and implicitly-generated move constructors and move assignment operators, among others.</li>
+
+  <li>Implemented support for some features of the upcoming C1x standard, including static assertions and generic selections.</li>
+  
+  <li>Better detection of include and linking paths for system headers and libraries, especially for Linux distributions.</li>
+
+  <li>Implemented support for <a href="http://clang.llvm.org/docs/AutomaticReferenceCounting.html">Automatic Reference Counting</a> for Objective-C.</li>
+
+  <li>Implemented a number of optimizations in <tt>libclang</tt>, the Clang C interface, to improve the performance of code completion and the mapping from source locations to abstract syntax tree nodes.</li>

+<li>The way the type system works has been rewritten: <code>PATypeHolder</code>
+and <code>OpaqueType</code> are gone, and all APIs deal with <code>Type*</code>
+instead of <code>const Type*</code>.
+If you need to create recursive structures, then create a named structure,

+merged with other structures, even if their layout is identical.
