+<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.
