## Next Release
### Added
- SVE target support is added to libm.
https://github.com/shibatch/sleef/pull/180
- SVE target support is added to DFT. With this patch, DFT operations
can be carried out using 256, 512, 1024 and 2048-bit wide vectors
according to runtime availability of vector registers and operators.
https://github.com/shibatch/sleef/pull/182
- 3.5-ULP versions of sinh, cosh, tanh, sinhf, coshf, tanhf, and the
corresponding testing functionalities are added.
https://github.com/shibatch/sleef/pull/192
- The whole build system of the project migrated from makefiles to
cmake. In particualr this includes `libsleef`, `libsleefgnuabi`,
`libdft` and all the tests.
- Benchmarks that compare `libsleef` vs `SVML` on X86 Linux are
available in the project tree under src/libm-benchmarks directory.
- Extensive upstream testing via Travis CI and Appveyor, on the
following systems:
* Compilers: gcc / clang / MSVC.
* Targets: X86 (SSE/AVX/AVX2/AVX512F), AArch64 (Advanced SIMD), ARM
(NEON). Emulators like QEMU or SDE can be used to run the tests.
- Added the following new vector functions (with relative testing):
* `log2`
- New compatibility tests have been added to check that
`libsleefgnuabi` exports the GNUABI symbols correctly.
- Added masked interface to the library to support AVX512F masked
vectorization.
### Changed
- Use native instructions if available for `sqrt`.
- Fixed fmax and fmin behavior on AArch64:
https://github.com/shibatch/sleef/pull/140
- Speed improvements for `asin`, `acos`, `fmod` and `log`. Computation
speed of other functions are also improved by general optimization.
https://github.com/shibatch/sleef/pull/97
- Removed `libm` dependency.
### Removed
- Makefile build system
