Updates the requirements on [lz4_flex](https://github.com/pseitz/lz4_flex) to permit the latest version. <details> <summary>Changelog</summary> <p><em>Sourced from <a href="https://github.com/PSeitz/lz4_flex/blob/main/CHANGELOG.md";>lz4_flex's changelog</a>.</em></p> <blockquote> <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 > ~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.
