-<li>The <a href="LangRef.html#i_shufflevector">shufflevector</a> instruction
-has been generalized to allow different shuffle mask width than its input
-vectors. This allows you to use shufflevector to combine two
-"<4 x float>" vectors into a "<8 x float>" for example.</li>
-
-<li>LLVM IR now supports new intrinsics for computing and acting on <a
-href="LangRef.html#int_overflow">overflow of integer operations</a>. This allows
-efficient code generation for languages that must trap or throw an exception on
-overflow. While these intrinsics work on all targets, they only generate
-efficient code on X86 so far.</li>
-
-<li>LLVM IR now supports a new <a href="LangRef.html#linkage">private
-linkage</a> type to produce labels that are stripped by the assembler before it
-produces a .o file (thus they are invisible to the linker).</li>
-
-<li>LLVM IR supports two new attributes for better alias analysis. The <a
-href="LangRef.html#paramattrs">noalias</a> attribute can now be used on the
-return value of a function to indicate that it returns new memory (e.g.
-'malloc', 'calloc', etc).
-The new <a href="LangRef.html#paramattrs">nocapture</a> attribute can be used
-on pointer arguments to indicate that the function does not return the pointer,
-store it in an object that outlives the call, or let the value of the pointer
-escape from the function in any other way.
-Note that it is the pointer itself that must not escape, not the value it
-points to: loading a value out of the pointer is perfectly fine.
-Many standard library functions (e.g. 'strlen', 'memcpy') have this property.
-<!-- The simplifylibcalls pass applies these attributes to standard libc functions. -->
-</li>
-
-<li>The parser for ".ll" files in lib/AsmParser is now completely rewritten as a
-recursive descent parser. This parser produces better error messages (including
-caret diagnostics), is less fragile (less likely to crash on strange things),
-does not leak memory, is more efficient, and eliminates LLVM's last use of the
-'bison' tool.</li>
-
-<li>Debug information representation and manipulation internals have been
- consolidated to use a new set of classes in
- <tt>llvm/Analysis/DebugInfo.h</tt>. These routines are more
- efficient, robust, and extensible and replace the older mechanisms.
- llvm-gcc, clang, and the code generator now use them to create and process
- debug information.</li>
+<li>LLVM IR now supports a 16-bit "half float" data type through <a
+ href="LangRef.html#int_fp16">two new intrinsics</a> and APFloat support.</li>
+<li>LLVM IR supports two new <a href="LangRef.html#fnattrs">function
+ attributes</a>: inlinehint and alignstack(n). The former is a hint to the
+ optimizer that a function was declared 'inline' and thus the inliner should
+ weight it higher when considering inlining it. The later
+ indicates to the code generator that the function diverges from the platform
+ ABI on stack alignment.</li>
+<li>The new <a href="LangRef.html#int_objectsize">llvm.objectsize</a> intrinsic
+ allows the optimizer to infer the sizes of memory objects in some cases.
+ This intrinsic is used to implement the GCC <tt>__builtin_object_size</tt>
+ extension.</li>
+<li>LLVM IR now supports marking load and store instructions with <a
+ href="LangRef.html#i_load">"non-temporal" hints</a> (building on the new
+ metadata feature). This hint encourages the code
+ generator to generate non-temporal accesses when possible, which are useful
+ for code that is carefully managing cache behavior. Currently, only the
+ X86 backend provides target support for this feature.</li>
+
+<li>LLVM 2.7 has pre-alpha support for <a
+ href="LangRef.html#t_union">unions in LLVM IR</a>.
+ Unfortunately, this support is not really usable in 2.7, so if you're
+ interested in pushing it forward, please help contribute to LLVM mainline.</li>
