infrastructure are described first, followed by language-specific
sections with improvements to Clang's support for those languages.
+Last release which will build as C++98
+--------------------------------------
+
+This is expected to be the last release of Clang which compiles using a C++98
+toolchain. We expect to start using some C++11 features in Clang starting after
+this release. That said, we are committed to supporting a reasonable set of
+modern C++ toolchains as the host compiler on all of the platforms. This will
+at least include Visual Studio 2012 on Windows, and Clang 3.1 or GCC 4.7.x on
+Mac and Linux. The final set of compilers (and the C++11 features they support)
+is not set in stone, but we wanted users of Clang to have a heads up that the
+next release will involve a substantial change in the host toolchain
+requirements.
+
+Note that this change is part of a change for the entire LLVM project, not just
+Clang.
