v1.0.9

SECURITY: decoder: fix integer overflow when input chunk is larger than 2GiB (CVE-2020-8927)

Other changes:

• add support WASM (emscripten) build
• brotli -v now reports raw / compressed size
• build files / docs maintenance
• reduce sources tarball size
• decoder: minor speed / memory usage improvements
• encoder: fix rare access to uninitialized data in ring-buffer
• encoder: improve support for platforms that does not have log2
• encoder: better support for MSVC (replacement for __builtin_clz and __builtin_ctzll
• python: decompress now reports error if there is unused after the end of compressed input

Brotli v1.0.2

This is a build-maintenance release. Major changes:

• added Autotools build files
• switched shared library version to libtool scheme

In this release semantic suffix and libtool suffix are the same: 1.0.2. Don't expect them to match in future releases.

Minor changes:

• BrotliDictionary members are not const now
• ZopfliNode distance could be up to 128MiB
• fixed API documentation typos
• total_out is always set by decoder

• fixed linter warnings in JS decoder
• fixed permissions of various files
• added Bazel build to Appveyor matrix
• added Sieve dictionary generator

Brotli v1.0.1

This is a source-only release. Binaries (except version) are the same

• updated README.md
• fixed parallel exeuction of CMake "compatibility" tests

Brotli v1.0.0

API changes

• new CLI; bro -> brotli; + man page
• remove "custom dictionary" support
• add ability to side-load brotli RFC dictionary
• add decoder API to avoid ringbuffer reallocation
• PY streaming decompression support
