v0.7.3
- Perf: improved speed for large inputs (~+20%)
- Perf: improved latency for small inputs (~10%)
- Perf: s390x Vectorial code, by @easyaspi314
- API: `xxhash.h` can now be included in any order, with and without `XXH_STATIC_LINKING_ONLY` and `XXH_INLINE_ALL`
- build: xxHash's implementation has been transferred into `xxhash.h`. There is no more need to have `xxhash.c` in the `/include` directory for `XXH_INLINE_ALL` to work
- build: VCpkg installation instructions, by @LilyWangL
- install: create pkg-config file, by @bket
- perf: improved speed for large inputs (~+20%)
- perf: improved latency for small inputs (~10%)
- perf: s390x Vectorial code, by @easyaspi314
- cli: improved support for Unicode filenames on Windows, thanks to @easyaspi314 and @t-mat
- api: `xxhash.h` can now be included in any order, with and without `XXH_STATIC_LINKING_ONLY` and `XXH_INLINE_ALL`
- build: xxHash's implementation transferred into `xxhash.h`. No more need to have `xxhash.c` in the `/include` directory for `XXH_INLINE_ALL` to work
- install: created pkg-config file, by @bket
- install: VCpkg installation instructions, by @LilyWangL
- doc: Highly improved code documentation, by @easyaspi314
- misc: New test tool in `/tests/collisions`: brute force collision tester for 64-bit hashes
