-* The CellSPU port has been removed. It can still be found in older versions.
-
-* The IR-level extended linker APIs (for example, to link bitcode files out of
- archives) have been removed. Any existing clients of these features should
- move to using a linker with integrated LTO support.
-
-* LLVM and Clang's documentation has been migrated to the `Sphinx
- <http://sphinx-doc.org/>`_ documentation generation system which uses
- easy-to-write reStructuredText. See `llvm/docs/README.txt` for more
- information.
-
-* TargetTransformInfo (TTI) is a new interface that can be used by IR-level
- passes to obtain target-specific information, such as the costs of
- instructions. Only "Lowering" passes such as LSR and the vectorizer are
- allowed to use the TTI infrastructure.
-
-* We've improved the X86 and ARM cost model.
-
-* The Attributes classes have been completely rewritten and expanded. They now
- support not only enumerated attributes and alignments, but "string"
- attributes, which are useful for passing information to code generation. See
- :doc:`HowToUseAttributes` for more details.
-
-* TableGen's syntax for instruction selection patterns has been simplified.
- Instead of specifying types indirectly with register classes, you should now
- specify types directly in the input patterns. See ``SparcInstrInfo.td`` for
- examples of the new syntax. The old syntax using register classes still
- works, but it will be removed in a future LLVM release.
