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.

0.11.6 (2026-03-14)

Security Fix

• Fix handling of invalid match offsets during decompression #84cdafb (thanks @​Marcono1234)

Invalid match offsets (offset == 0) during decompression were not properly
handled, which could lead to invalid memory reads on untrusted input.
Users on 0.11.x should upgrade to 0.11.6.
