Changelog

Sourced from lz4_flex's changelog.

0.12.0 (2025-11-11)

• Fix integer overflows when decoding large payloads #192 (thanks @​teh-cmc)

This fixes an u32 integer overflow when decoding large payloads in the block format.
Note: The block format is not suitable for such large payloads, since it
keeps everything in memory. Consider using the frame format for large data.
This change also removes a unsafe fast-path for write_integer to simplify the code.
The performance impact is on incompressible data, which is already fast enough.

0.11.5 (2025-06-19)

• Fix incorrect rust-version field name in Cargo.toml #187

0.11.4 (2025-06-14)

• Upgrade to twox-hash 2.0#175
• Better no_std compatibility #180

0.11.3 (2024-03-30)

• Fix support for --deny=unsafe_code compilation #152
• make get_maximum_output_size const #153

0.11.2 (2024-01-11)

• Include license file in the published crate

0.11.1 (2023-06-19)

• [breaking] remove unchecked-decode Remove unchecked-decode feature-flag, because of feature unification: https://doc.rust-lang.org/cargo/reference/features.html#feature-unification

0.11.0 (2023-06-18)

Documentation

• Docs: add decompress block example

Fixes

• Handle empty input in Frame Format #120

Empty input was ignored previously and didn't write anything. Now an empty Frame is written. This improves compatibility with the reference implementation and some corner cases.
