Changelog

Sourced from lz4_flex's changelog.

0.13.0 (2026-03-15)

Features

• Add option to reuse compression dict #207 (thanks @​matthewfollegot)

Fixes

• Fix handling of invalid match offsets during decompression #055502e (thanks @​Marcono1234)

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.

0.12.2 (2026-05-09)

Fixes

• Fix compression with short dictionaries (less than 4 bytes), avoiding a panic/out-of-bounds read #222

Compression with dictionaries shorter than the minimum match length of 4 now falls
back to compression without a dictionary instead of panicking or reading past
the dictionary. 
This is a security fix for unsafe compression with untrusted dictionaries.

Users on 0.12.1 should upgrade to 0.12.2.
