- update to 1.20:
  * Improved CRC-32 performance on recent x86 CPUs by adding
  * VPCLMULQDQ-accelerated implementations using 256-bit and
    512-bit vectors.
  * Improved Adler-32 performance on recent x86 CPUs by adding
  * VNNI-accelerated implementations using 256-bit and 512-bit
    vectors.
  * Improved CRC-32 and Adler-32 performance on short inputs.
  * Optimized the portable implementation of Adler-32.
  * Added some basic optimizations for RISC-V.
  * Dropped support for gcc versions older than v4.9 (released in
    2014) and clang versions older than v3.9 (released in 2016).
  * Dropped support for CRC-32 acceleration on 32-bit ARM using
    the ARMv8 pmull or crc32 instructions.

- update to 1.19:
  * Added new functions `libdeflate_alloc_compressor_ex()` and
    `libdeflate_alloc_decompressor_ex()`.  These functions allow
    specifying a custom memory allocator on a per-compressor basis.
  * libdeflate now always generates Huffman codes with at least 2
    codewords. This fixes a compatibility issue where Windows
    Explorer's ZIP unpacker could not decompress DEFLATE streams
    created by libdeflate.  libdeflate's behavior was
  * allowed by the DEFLATE RFC, but not all software was okay
    with it.  In rare cases, compression ratios can be slightly
    reduced by this change.
  * Disabled the use of some compiler intrinsics on MSVC versions
    where they don't work correctly.
  * libdeflate can now compress up to the exact size of the
    output buffer.
  * Slightly improved compression performance at levels 1-9.
  * Improved the compression ratio of very short inputs.

    building with Clang 15 or later (x86), or with Clang 16
  * Fixed a couple macOS compatibility issues with the gzip program.
  * Cleaned up a few things in the compression code.
- Add workaround build fail due issue in dwz by deleting
  libdeflate-gunzip and replace with symlink libdeflate-gzip to

- update to 1.18:
  * Fixed a bug where the build type didn't default to "Release"
    when using CMake 3.10 or earlier.
  * Fixed a bug where some optimized code wasn't used when
    building with Clang 15 or later (x86), or with Clang 16 
    or later (aarch64).
  * Fixed build errors with some architecture and compiler
    combos:
    * aarch64 with Clang 16
    * armv6kz or armv7e-m with gcc
    * armhf with gcc (on Debian only)

- update to 1.17:
  * Improved the compression ratio at levels 10-12 slightly, mainly
    levels 11-12. Some inputs (such as certain PNG files) see much
    improved compression ratios. As a trade-off, compressing at
    levels 11-12 is now about 5-20% slower.
  * For consistency with zlib, the decompressor now returns an error
    on some invalid inputs that were accepted before.
  * Fixed a build error on arm64 with gcc with certain target CPUs.
  * Fixed a build error in programs/gzip.c with uClibc.

- update to 1.14:
  Significantly improved decompression performance on all platforms.  Examples
  include (measuring DEFLATE only):
  | Platform                           | Speedup over v1.13 |
  |------------------------------------|--------------------|
  | x86_64 (Intel Comet Lake), gcc     | 1.287x             |

- update to 1.13:
  * Changed the 32-bit Windows build of the library to use the default calling
    convention (cdecl) instead of stdcall, reverting a change from libdeflate 1.4.
  * Fixed a couple macOS compatibility issues with the gzip program.

- update to 1.12:
  * Improved CRC-32 performance on short inputs on x86 and ARM.
  * Improved CRC-32 performance on Apple Silicon Macs by using a 12-way pmull
    implementation.   Performance on large inputs on M1 is now about 67 GB/s,
    compared to 8 GB/s before, or 31 GB/s with the Apple-provided zlib.
  * Improved CRC-32 performance on some other ARM CPUs by reworking the code so
    that multiple crc32 instructions can be issued in parallel.
  * Improved CRC-32 performance on some x86 CPUs by increasing the stride length
    of the pclmul implementation.
  * Improved Adler-32 performance on some x86 CPUs by optimizing the AVX-2
    implementation.  E.g., performance on Zen 1 improved from 19 to 30 GB/s, and
    on Ice Lake from 35 to 41 GB/s (if the AVX-512 implementation is excluded).
  * Removed the AVX-512 implementation of Adler-32 to avoid CPU frequency
    downclocking, and because the AVX-2 implementation was made faster.
  * Improved Adler-32 performance on some ARM CPUs by optimizing the NEON
  * Improved compression performance slightly.
  * Detect arm64 CPU features on Apple platforms, which should improve
    performance in some areas such as CRC-32 computation.
  * The included `gzip` and `gunzip` programs now support the `-q` option.
  * The included `gunzip` program now passes through non-gzip data when both
    the `-f` and `-c` options are used.
