Changes from 1.20.0 to 1.20.1

  • Added <unistd.h> in vendored zlib 1.2.8 for compatibility with Python 3.8 in recent Mac OSX. For details, see: Blosc/python-blosc#229.

Changes from 1.19.1 to 1.20.0

  • More saftey checks have been implemented so that potential flaws
    discovered by new fuzzers in OSS-Fuzzer are fixed now. Thanks to
    Nathan Moinvaziri (@nmoinvaz).

  • BloscLZ updated to 2.3.0. Expect better compression ratios for faster
    codecs. For details, see our new blog post:
    https://blosc.org/posts/beast-release/

  • Fixed the _xgetbv() collision. Thanks to Michał Górny (@mgorny).

  • The chunk format has been fully described so that 3rd party software
    may come with a different implementation, but still compatible with
    C-Blosc chunks.

Changes from 1.18.1 to 1.19.0

  • The length of automatic blocksizes for fast codecs (lz4, blosclz) has
    been incremented quite a bit (up to 256 KB) for better compression ratios.
    The performance in modern CPUs (with at least 256 KB in L2 cache) should
    be better too (for older CPUs the performance should stay roughly the same).

  • Continuous integration has been migrated to GitHub actions and much
    more scenarios are tested (specially linking with external codecs).
    Also, a new OSS-Fuzz workflow has been added for increased detection
    of possible vulnerabilities. Thanks to Nathan Moinvaziri.

  • For small buffers that cannot be compressed (typically < 128 bytes),
    blosc_compress() returns now a 0 (cannot compress) instead of a negative
    number (internal error). See #294.
    Thanks to @kalvdans for providing the initial patch.

  • blosclz codec updated to 2.1.0. Expect better compression ratios and
    performance in a wider variety of scenarios.

  • blosc_decompress_unsafe(), blosc_decompress_ctx_unsafe() and
    blosc_getitem_unsafe() have been removed because they are dangerous
    and after latest improvements, they should not be used in production.

  • zstd codec updated to 1.4.5.

  • Conan packaging has been deprecated (from now on, we should try
    to focus on supporting wheels only).

Changes from 1.17.1 to 1.18.1

  • Fixed the copy of the leftovers of a chunk when its size is not a
    multiple of the typesize. Although this is a very unusual situation,
    it can certainly happen (e.g. Blosc/python-blosc#220).

@FrancescAlted FrancescAlted released this Dec 12, 2019 · 102 commits to master since this release

Changes from 1.17.0 to 1.17.1

  • Zstd codec updated to 1.4.4.

  • LZ4 codec updated to 1.9.2.

Changes from 1.16.3 to 1.17.0

  • LZ4 codec updated to 1.9.1.

  • Zstd codec updated to 1.4.1.

  • BloscLZ codec updated to 2.0.0. Although this should be fully backward
    compatible, it contains important changes that affects mainly speed, but
    also compression ratios. Feedback on how it behaves on your own data is
    appreciated.
