Updates the requirements on lz4_flex to permit the latest version.

Changelog

Sourced from lz4_flex's changelog.

0.13.0 (2026-03-15)

Features

Fixes

Invalid match offsets (offset == 0) during decompression were not properly
handled, which could lead to invalid memory reads. This is a security fix
that was also backported to 0.12.1 and 0.11.6.
  • Fix get_maximum_output_size overflow on 32-bit targets #205 (thanks @​dglittle)
Cast input_len to u64 before multiplying by 110, avoiding overflow on
32-bit targets (e.g. wasm32) where input_len * 110 overflows usize
when input_len > ~39MB.

0.12.1 (2026-03-14)

Security Fix

Invalid match offsets (offset == 0) during decompression were not properly
handled, which could lead to invalid memory reads on untrusted input.
Users on 0.12.x should upgrade to 0.12.1.

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

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.
