If this affects you, please upgrade your compiler. - - New API function: libdeflate_zlib_decompress_ex(). It provides - the actual size of the stream that was decompressed, like the - gzip and DEFLATE equivalents. - - libdeflate_zlib_decompress() now accepts trailing bytes after - the end of the stream, like the gzip and DEFLATE equivalents. - - Added support for custom memory allocators. - (New API function: libdeflate_set_memory_allocator()) - - Added support for building the library in freestanding mode. - - Building libdeflate no longer requires CPPFLAGS=-Icommon. - -Version 1.5: - Fixed up stdcall support on 32-bit Windows: the functions are - now exported using both suffixed and non-suffixed names, and - fixed libdeflate.h to be MSVC-compatible again. - -Version 1.4: - The 32-bit Windows build of libdeflate now uses the "stdcall" - calling convention instead of "cdecl". If you're calling - libdeflate.dll directly from C or C++, you'll need to recompile - your code. If you're calling it from another language, or - calling it indirectly using LoadLibrary(), you'll need to update - your code to use the stdcall calling convention. - - The Makefile now supports building libdeflate as a shared - library (.dylib) on macOS. - - Fixed a bug where support for certain optimizations and optional - features (file access hints and more precise timestamps) was - incorrectly omitted when libdeflate was compiled with -Werror. - - Added 'make check' target to the Makefile. - - Added CI configuration files. - -Version 1.3: - `make install` now supports customizing the directories into - which binaries, headers, and libraries are installed. - - `make install` now installs into /usr/local by default. - To change it, use e.g. `make install PREFIX=/usr`. - - `make install` now works on more platforms. - - The Makefile now supports overriding the optimization flags. - - The compression functions now correctly handle an output data - buffer >= 4 GiB in size, and `gzip` and `gunzip` now correctly - handle multi-gigabyte files (if enough memory is available). - -Version 1.2: - Slight improvements to decompression speed. - - Added an AVX-512BW implementation of Adler-32. - - The Makefile now supports a user-specified installation PREFIX. - - Fixed build error with some Visual Studio versions. - -Version 1.1: - Fixed crash in CRC-32 code when the prebuilt libdeflate for - 32-bit Windows was called by a program built with Visual Studio. - - Improved the worst-case decompression speed of malicious data. - - Fixed build error when compiling for an ARM processor without - hardware floating point support. - - Improved performance on the PowerPC64 architecture. - - Added soname to libdeflate.so, to make packaging easier. - - Added 'make install' target to the Makefile. - - The Makefile now supports user-specified CPPFLAGS. - - The Windows binary releases now include the import library for - libdeflate.dll. libdeflate.lib is now the import library, and - libdeflatestatic.lib is the static library. - -Version 1.0: - Added support for multi-member gzip files. - - Moved architecture-specific code into subdirectories. If you - aren't using the provided Makefile to build libdeflate, you now - need to compile lib/*.c and lib/*/*.c instead of just lib/*.c. - - Added an ARM PMULL implementation of CRC-32, which speeds up - gzip compression and decompression on 32-bit and 64-bit ARM - processors that have the Cryptography Extensions. - - Improved detection of CPU features, resulting in accelerated - functions being used in more cases. This includes: - - - Detect CPU features on 32-bit x86, not just 64-bit as was - done previously. - - - Detect CPU features on ARM, both 32 and 64-bit. - (Limited to Linux only currently.) - -Version 0.8: - Build fixes for certain platforms and compilers. - - libdeflate now produces the same output on all CPU architectures. - - Improved documentation for building libdeflate on Windows. - -Version 0.7: - Fixed a very rare bug that caused data to be compressed incorrectly. - The bug affected compression levels 7 and below since libdeflate v0.2. - Although there have been no user reports of the bug, and I believe it - would have been highly unlikely to encounter on realistic data, it could - occur on data specially crafted to reproduce it. - - Fixed a compilation error when building with clang 3.7. - -Version 0.6: - Various improvements to the gzip program's behavior. - - Faster CRC-32 on AVX-capable processors. - - Other minor changes. - -Version 0.5: - The CRC-32 checksum algorithm has been optimized with carryless - multiplication instructions for x86_64 (PCLMUL). This speeds up gzip - compression and decompression. - - Build fixes for certain platforms and compilers. - - Added more test programs and scripts. - - libdeflate is now entirely MIT-licensed. - -Version 0.4: - The Adler-32 checksum algorithm has been optimized with vector - instructions for x86_64 (SSE2 and AVX2) and ARM (NEON). This speeds up - zlib compression and decompression. - - To avoid naming collisions, functions and definitions in libdeflate's - API have been renamed to be prefixed with "libdeflate_" or - "LIBDEFLATE_". Programs using the old API will need to be updated. - - Various bug fixes and other improvements. - -Version 0.3: - Some bug fixes and other minor changes. - -Version 0.2: - Implemented a new block splitting algorithm which typically improves the - compression ratio slightly at all compression levels. - - The compressor now outputs each block using the cheapest type (dynamic - Huffman, static Huffman, or uncompressed). - - The gzip program has received an overhaul and now behaves more like the - standard version. - - Build system updates, including: some build options were changed and - some build options were removed, and the default 'make' target now - includes the gzip program as well as the library. - -Version 0.1: - Initial official release. |
