 API changes are:</p>
 
 <ul>
-<li>All uses of <tt>hash_set</tt> and <tt>hash_map</tt> have been removed from
-    the LLVM tree and the wrapper headers have been removed.</li>
-<li>The llvm/Streams.h and <tt>DOUT</tt> member of Debug.h have been removed.  The
-    <tt>llvm::Ostream</tt> class has been completely removed and replaced with
-    uses of <tt>raw_ostream</tt>.</li>
-<li>LLVM's global uniquing tables for <tt>Type</tt>s and <tt>Constant</tt>s have
-    been privatized into members of an <tt>LLVMContext</tt>.  A number of APIs
-    now take an <tt>LLVMContext</tt> as a parameter.  To smooth the transition
-    for clients that will only ever use a single context, the new 
-    <tt>getGlobalContext()</tt> API can be used to access a default global 
-    context which can be passed in any and all cases where a context is 
-    required.
-<li>The <tt>getABITypeSize</tt> methods are now called <tt>getAllocSize</tt>.</li>
-<li>The <tt>Add</tt>, <tt>Sub</tt> and <tt>Mul</tt> operators are no longer
-    overloaded for floating-point types. Floating-point addition, subtraction
-    and multiplication are now represented with new operators <tt>FAdd</tt>,
-    <tt>FSub</tt> and <tt>FMul</tt>. In the <tt>IRBuilder</tt> API,
-    <tt>CreateAdd</tt>, <tt>CreateSub</tt>, <tt>CreateMul</tt> and
-    <tt>CreateNeg</tt> should only be used for integer arithmetic now;
-    <tt>CreateFAdd</tt>, <tt>CreateFSub</tt>, <tt>CreateFMul</tt> and
-    <tt>CreateFNeg</tt> should now be used for floating-point arithmetic.</li>
-<li>The <tt>DynamicLibrary</tt> class can no longer be constructed, its functionality has
-    moved to static member functions.</li>
-<li><tt>raw_fd_ostream</tt>'s constructor for opening a given filename now
-    takes an extra <tt>Force</tt> argument. If <tt>Force</tt> is set to
-    <tt>false</tt>, an error will be reported if a file with the given name
-    already exists. If <tt>Force</tt> is set to <tt>true</tt>, the file will
-    be silently truncated (which is the behavior before this flag was
-    added).</li>
-<li><tt>SCEVHandle</tt> no longer exists, because reference counting is no
-    longer done for <tt>SCEV*</tt> objects, instead <tt>const SCEV*</tt>
-    should be used.</li>
-
-<li>Many APIs, notably <tt>llvm::Value</tt>, now use the <tt>StringRef</tt>
-and <tt>Twine</tt> classes instead of passing <tt>const char*</tt>
-or <tt>std::string</tt>, as described in
-the <a href="ProgrammersManual.html#string_apis">Programmer's Manual</a>. Most
-clients should be unaffected by this transition, unless they are used to
-<tt>Value::getName()</tt> returning a string. Here are some tips on updating to
-2.6:
-  <ul>
-    <li><tt>getNameStr()</tt> is still available, and matches the old
-      behavior. Replacing <tt>getName()</tt> calls with this is an safe option,
-      although more efficient alternatives are now possible.</li>
-
-    <li>If you were just relying on <tt>getName()</tt> being able to be sent to
-      a <tt>std::ostream</tt>, consider migrating
-      to <tt>llvm::raw_ostream</tt>.</li>
-      
-    <li>If you were using <tt>getName().c_str()</tt> to get a <tt>const
-        char*</tt> pointer to the name, you can use <tt>getName().data()</tt>.
-        Note that this string (as before), may not be the entire name if the
-        name contains embedded null characters.</li>
-
-    <li>If you were using <tt>operator +</tt> on the result of <tt>getName()</tt> and
-      treating the result as an <tt>std::string</tt>, you can either
-      use <tt>Twine::str</tt> to get the result as an <tt>std::string</tt>, or
-      could move to a <tt>Twine</tt> based design.</li>
-
-    <li><tt>isName()</tt> should be replaced with comparison
-      against <tt>getName()</tt> (this is now efficient).
-  </ul>
-</li>
