- Valentin Haenel did a terrific work implementing the support for the Snappy compression, fixing typos and improving docs and the plotting script.
- Thibault North, with ideas from Oscar Villellas, contributed a way to call Blosc from different threads in a safe way. Christopher Speller introduced contexts so that a global lock is not necessary anymore.
- The CMake support was initially contributed by Thibault North, and Antonio Valentino and Mark Wiebe made great enhancements to it.
- Christopher Speller also introduced the two new '_ctx' calls to avoid the use of the blosc_init() and blosc_destroy().
- Jack Pappas contributed important portability enhancements, specially runtime and cross-platform detection of SSE2/AVX2 as well as high precision timers (HPET) for the benchmark program.
- @littlezhou implemented the AVX2 version of shuffle routines.
- Julian Taylor contributed a way to detect AVX2 in runtime and calling the appropriate routines only if the underlying hardware supports it.
- Lucian Marc provided the support for ARM/NEON for the shuffle filter.
- Jerome Kieffer contributed support for PowerPC/ALTIVEC for the shuffle/bitshuffle filter.
- Alberto Sabater, for his great efforts on producing really nice Blosc2 docs, among other aspects.
- Kiyo Masui for relicensing his bitshuffle project for allowing the inclusion of part of his code in Blosc.
- Aleix Alcacer for his implementation of mutable super-chunks, multiple variable length metalayers and many other things.
- Oscar Guiñón for the optimization of reading a (sparse) set of blocks of a chunk in parallel.
- Nathan Moinvaziri for his outstanding work on the security side of the things via fuzzer testing.
- Marta Iborra for her implementation of sparse storage for persistent super-chunks.
