<h1>0.13.0 (2026-03-15)</h1>
<h3>Features</h3>
<ul>
<li>Add option to reuse compression dict <a
href="https://redirect.github.com/PSeitz/lz4_flex/pull/207">#207</a>
(thanks <a
href="https://github.com/matthewfollegot"><code>@​matthewfollegot</code></a>)</li>
</ul>
<h3>Fixes</h3>
<ul>
<li>Fix handling of invalid match offsets during decompression <a
href="https://github.com/PSeitz/lz4_flex/commit/055502e">#055502e</a>
(thanks <a
href="https://github.com/Marcono1234"><code>@​Marcono1234</code></a>)</li>
</ul>
<pre><code>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.
</code></pre>
<ul>
<li>Fix <code>get_maximum_output_size</code> overflow on 32-bit targets
<a href="https://redirect.github.com/PSeitz/lz4_flex/pull/205">#205</a>
(thanks <a
href="https://github.com/dglittle"><code>@​dglittle</code></a>)</li>
</ul>
<pre><code>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 &gt; ~39MB.
</code></pre>
<h1>0.12.1 (2026-03-14)</h1>
<h3>Security Fix</h3>
<ul>
<li>Fix handling of invalid match offsets during decompression <a
href="https://github.com/PSeitz/lz4_flex/commit/a0b9154">#a0b9154</a>
(thanks <a
href="https://github.com/Marcono1234"><code>@​Marcono1234</code></a>)</li>
</ul>
<pre><code>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.
</code></pre>
<h1>0.12.0 (2025-11-11)</h1>
<ul>
<li>Fix integer overflows when decoding large payloads <a
href="https://redirect.github.com/PSeitz/lz4_flex/pull/192">#192</a>
(thanks <a
href="https://github.com/teh-cmc"><code>@​teh-cmc</code></a>)</li>
</ul>
<pre><code>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.
<p>This change also removes a unsafe fast-path for write_integer to
simplify the code.<br />
The performance impact is on incompressible data, which is already fast
enough.<br />
</code></pre></p>
<h1>0.11.6 (2026-03-14)</h1>
<h3>Security Fix</h3>
<ul>
<li>Fix handling of invalid match offsets during decompression <a
href="https://github.com/PSeitz/lz4_flex/commit/84cdafb">#84cdafb</a>
(thanks <a
href="https://github.com/Marcono1234"><code>@​Marcono1234</code></a>)</li>
</ul>
<pre><code>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.
