Some of C++17 library features may be missing, in this case KFR uses custom implementation +- `cast` function now works with both vectors and expressions (expression versions was previously called `convert`) +- Memory alignment can be up to 32768 +- New implementation for `cometa::function` using shared pointer +- `memory.hpp` allocation functions has been moved to cometa +- `cconj` has been moved to simd module (instead of `math`) +- dr_libs version updated +- All global constants are now `inline constexpr` +- enums moved out of architecture namespace +- `special_constant::undefined` removed + +#### Fixed + +- Fixed real DFT with raw poitners +- Bug with generators +- Fixed grid issues in dspplot +- Wrong index in `concatenate` +- `csqrt` function +- Fixed NaNs in `amp_to_dB` +- GCC 9 support +- Workaround for Clang 8.0 FMA code generator bug +- Flat top window +- SSE4.2 detection (previously detected as SSE4.1) + +#### Notes + +* MSVC support is limited to MSVC2017 due to ICE in MSVC2019. Once fixed, support will be added +* DFT is limited to Clang due to ICE in MSVC and broken AVX optimization in GCC 8 and 9. Once fixed, support will be added + ## 3.0.9 2019-04-02
