What's Changed

This patch release provides important bug fixes, including a fix for API compatibility with 3.5 (#534).
The support and test for some features is still limited, as documented in README,
however significant progress was made in order to test on Linux, macOS and Windows.

Added

• Add support for RISC-V in DFT, QUAD and inline headers (#503, #522).
• Add GHA workflow to run CI tests on Windows x86 (#540)
  and macOS on x86 and aarch64 (#543). And update test matrix.
• Add GHA workflows to run examples in CI (#550).

Changed

• Cleanup/Improve support for RISC-V in LIBM (#520, #521).
• Update supported environment in documentation (#529, #549),
  including website and test matrix from README.

Fixed

• Major fix and cleanup of CMakeLists.txt (#531).
• Fix compatibility issue after removal of quad and long double
  sincospi (#545). Restores functions that are missing in 3.6 (#534).
• Various bug fixes (#528, #533, #536, #537).
