Snappy 1.2.2

• We fixed a very old issue of data corruption when compressed size
  exceeds 4GB. This can happen when you compress data close to 4GB
  and it's incompressible, for example, random data.

• Started to use minimum CMake 3.10 because older ones are not
  planned to be supported.

• Various other small fixes

Snappy 1.2.1

• We restored old functions/symbols after reports of ABI incompatibility apache/arrow#41058 conda-forge/snappy-feedstock#35 #183

If you depend on ABI, consider using this release.

Snappy 1.2.0

• Level API was added with level 2 support. Compresses 5-10% denser and decompresses 5-10% faster. The compression speed drop is about 20-30%
• Minor fixes

Snappy 1.1.10

• Performance improvements
• Compilation fixes for various environments

Snappy 1.1.9

• Performance improvements.
• Google Test and Google Benchmark are now bundled in third_party/.

Snappy 1.1.8

• Small performance improvements.
• Removed snappy::string alias for std::string.
• Improved CMake configuration.

Snappy 1.1.7

• Improved CMake build support for 64-bit Linux distributions.
• MSVC builds now use MSVC-specific intrinsics that map to clzll.
• ARM64 (AArch64) builds use the code paths optimized for 64-bit processors.

Snappy 1.1.6

This is a re-release of v1.1.5 with proper SONAME / SOVERSION values.

Snappy 1.1.5

This release has broken SONAME / SOVERSION values. Users of snappy as a shared library should avoid 1.1.5 and use 1.1.6 instead. SONAME / SOVERSION errors will manifest as the dynamic library loader complaining that it cannot find snappy's shared library file (libsnappy.so / libsnappy.dylib), or that the library it found does not have the required version. 1.1.6 has the same code as 1.1.5, but carries build configuration fixes for the issues above.

• Add CMake build support. The autoconf build support is now deprecated, and will be removed in the next release.
• Add AppVeyor configuration, for Windows CI coverage.
• Small performance improvement on little-endian PowerPC.
• Small performance improvement on LLVM with position-independent executables.
• Fix a few issues with various build environments.

Snappy 1.1.4

• Fix a 1% performance regression when snappy is used in PIE executables.
• Improve compression performance by 5%.
• Improve decompression performance by 20%.
