Summary: Hash-based predictive Lempel-Ziv compressor
LZ4 is a lossless data compression algorithm that is focused on
compression and decompression speed. It belongs to the LZ77
(Lempel–Ziv) family of byte-oriented compression schemes. It is a

This subpackage contains the (de)compressor code as a shared library.

      information, compressed and decompressed sizes (if present). The
      command is limited to single-frame files for the time being.

      rare conditions

      number of bytes requested

    * speed inprovemtns for compression and decompression
    * fix compression compatible with low memory addresses
    * fix decompression segfault when provided with NULL input
    * cli: new command --favor-decSpeed
    * cli: benchmark mode more accurate for small inputs
* Wed Feb 07 2018
  - Update to new upstream release
    * Most visible new feature is support for dictionary compression
    * Support is now more formally added on the API side within
      lib/lz4frame_static.h. It's early days, and this new API is
      tagged "experimental" for the time being.
    * Support is also added in the command line utility lz4, using
      the new command -D. The behavior of this command is identical
      to zstd, should you be already familiar.
    * lz4 doesn't specify how to build a dictionary. All it says is
      that it can be any file up to 64 KB.
    * This approach is compatible with zstd dictionary builder, which
      can be instructed to create a 64 KB dictionary.
    * Improved performance at ultra settings (levels 10+).
    * These levels receive a new code, called optimal parser,
      available in lib/lz4_opt.h.
    * New parser uses less memory (from 384KB to 256KB), performs
      faster, compresses a little bit better (not much, as it was
      already close to theoretical limit), and resists pathological
      patterns which could destroy performance.
    * New parser is directly compatible with lower compression levels,
      which brings additional benefits:
      + Compatibility with LZ4_*_destSize() variant, which reverses
      the logic by trying to fit as much data as possible into a
      predefined limited size buffer.
      + Compatibility with Dictionary compression, as it uses the
      same tables as regular HC mode
    * In the future, this compatibility will also allow dynamic change
      of compression level.
    * Small set of bug fixes and improvements:
      + perf : faster and stronger ultra modes (levels 10+)
      + perf : slightly faster compression and decompression speed
      + perf : fix bad degenerative case
      + fix : decompression failed when using a combination of
      extDict + low memory address
      + cli : support for dictionary compression (-D)
      + cli : fix : lz4 -d --rm preserves timestamp
      + cli : fix : do not modify /dev/null permission as root
      + api : _destSize() variant supported for all compression
  - partial cleanup with spec-cleaner
  - drop lz4-use-shlib.diff, breaks build
  - misc spec cleanups
    - remove Makefile fix
    - build and install separately
    - New URL
* Fri Aug 25 2017
  - Update to new upstream release 1.8.0
    * cli: fix: do not modify /dev/null's permissions.
    * cli: added POSIX separator "--" for specifying that all
      following arguments are non-options.
    * cli: restored -BX command enabling block checksum.
    * API: added LZ4_compress_HC_destSize() and
    * API: lz4frame: negative compression levels trigger fast
    * API: lz4frame: ability to control block checksum and
      dictionary ID.
    * API: fix: expose obsolete decoding functions
    * API: experimental: lz4frame_static.h:
      new dictionary compression API
    * doc: Updated LZ4 Frame format to v1.6.0, restoring
      Dictionary ID field in header.
