After delays pushed its release back by about one month, LLVM 5.0 was just released a few minutes ago along with its associated sub-projects like the Clang 5.0 C/C++ compiler.

LLVM 5.0 features a number of improvements to the ARM and MIPS targets, greater support for the POWER ISA 3.0 in the PowerPC target, the initial AMD Ryzen (znver1) scheduler support (already improved in LLVM 6.0 SVN), support for Intel Goldmont CPUs, greater AVX-512 support, improved Silvermont/Sandybridge/Jaguar schedulers, and initial Radeon Vega (GFX9) support within the AMDGPU target.

On the Clang 5.0 front there is effectively complete C++17 support, handling for the C++ coroutines technical specification, Object-C improvements, and various other C/C++ improvements.

Clang 5.0 is expected to be the last release defaulting to GNU++98 as its C++ standard while with Clang 6.0 and newer they expect to be defaulting to GNU++14 by default.

There are also ELF improvements in LLD and other linker enhancements, among many other changes.

More details on LLVM 5.0 can be found via the release announcement and previously in Changes To Look Forward To With LLVM/Clang 5.0.
