Changelog#

The changelog of the Rust crate is available here.

[0.3.0]https://github.com/vlaci/lzallright/tree/v0.3.0) - 2026-10-07#

Changed#

• Reimplemented the C++ lzokay based code in Safe Rust. Building no longer needs a C++ toolchain. The codec is also published as the separately versioned lzallright Rust crate; see its changelog for details.
• Updated PyO3 to 0.29; MSRV is bumped to 1.83
• Minimum supported Python version is now 3.11. Free-threaded wheels are built for 3.14t. x86_64 macOS wheels are no longer published.
• Published wheels are now built with Profile-Guided Optimization, trained on the benchmark corpus.

Fixed#

• Compressing empty input now produces a valid LZO stream; previously it could not be decompressed.
• Inputs other than bytes are copied before the GIL is released. Writing to the source buffer during compression or decompression, for example through the bytearray behind a read-only memoryview, could previously corrupt the result.
