+* As `discussed on the mailing list
+ <https://lists.llvm.org/pipermail/llvm-dev/2019-January/129452.html>`_,
+ building LLVM will soon require more recent toolchains as follows:
+
+ ============= ====
+ Clang 3.5
+ Apple Clang 6.0
+ GCC 5.1
+ Visual Studio 2017
+ ============= ====

+ A new CMake check when configuring LLVM provides a soft-error if your
+ toolchain will become unsupported soon. You can opt out of the soft-error by
+ setting the ``LLVM_TEMPORARILY_ALLOW_OLD_TOOLCHAIN`` CMake variable to
+ ``ON``.
+
* The **llvm-cov** tool can now export lcov trace files using the
`-format=lcov` option of the `export` command.
