<summary>Release notes</summary>
<p><em>Sourced from <a href="https://github.com/starkat99/half-rs/releases">half's releases</a>.</em></p>
<blockquote>
<h2>1.8.2</h2>
<h3>Fixed</h3>
<ul>
<li>Remove cargo resolver=2 from manifest to resolve errors in older versions of Rust that still worked with 1.8.0. Going forward, MSRV increases will be major version increases. Fixes <a href="https://github-redirect.dependabot.com/starkat99/half-rs/issues/48">#48</a>.</li>
</ul>
<h2>1.8.1 [YANKED]</h2>
<h3><em><strong>Yanked</strong></em></h3>
<p><em>Not recommended due to introducing compilation error in Rust versions that worked with 1.8.0.</em></p>
<h3>Changed</h3>
<ul>
<li>Now uses cargo resolver version 2 to prevent dev-dependencies from enabling <code>std</code> feature on optional dependencies.</li>
</ul>
<h3>Fixed</h3>
<ul>
<li>Fixed compile failure when <code>std</code> feature is not enabled and <code>num-traits</code> is enabled under new resolver. Now properly uses <code>libm</code> num-traits feature.</li>
</ul>
<h2>1.8.0</h2>
<h3>Changed</h3>
<ul>
<li>Now always implements <code>Add</code>, <code>Div</code>, <code>Mul</code>, <code>Neg</code>, <code>Rem</code>, and <code>Sub</code> traits. Previously, these were only implemented under the <code>num-traits</code> feature. Keep in mind they still convert to <code>f32</code> and back in the implementation.</li>
<li>Minimum supported Rust version is now 1.51.</li>
<li>Made crate package <a href="https://reuse.software/">REUSE compliant</a>.</li>
<li>Docs now use intra-doc links instead of manual (and hard to maintain) links.</li>
<li>The following methods on both <code>f16</code> and <code>bf16</code> are now <code>const</code>:
<ul>
<li><code>to_le_bytes</code></li>
<li><code>to_be_bytes</code></li>
<li><code>to_ne_bytes</code></li>
<li><code>from_le_bytes</code></li>
<li><code>from_be_bytes</code></li>
<li><code>from_ne_bytes</code></li>
<li><code>is_normal</code></li>
<li><code>classify</code></li>
<li><code>signum</code></li>
</ul>
</li>
</ul>
<h3>Added</h3>
<ul>
<li>Added optional implementations of <code>zerocopy</code> traits <code>AsBytes</code> and <code>FromBytes</code> under <code>zerocopy</code> cargo feature. By <a href="https://github.com/samcrow"><code>@​samcrow</code></a>.</li>
<li>Implemented the <code>core::iter::Product</code> and <code>core::iter::Sum</code> traits, with the same caveat as above about converting to <code>f32</code> and back under the hood.</li>
<li>Added new associated const <code>NEG_ONE</code> to both <code>f16</code> and <code>bf16</code>.</li>
<li>Added the following new methods on both <code>f16</code> and <code>bf16</code>:
<ul>
<li><code>copysign</code></li>
<li><code>max</code></li>
<li><code>min</code></li>
<li><code>clamp</code></li>
</ul>
</li>
</ul>
<h3>Fixed</h3>
<ul>
<li>Fixed a number of minor lints discovered due to improved CI.</li>
</ul>
<h2>1.7.1</h2>
<h3>Fixed</h3>
<ul>
<li>Docs.rs now generates docs for <code>bytemuck</code> and <code>num-traits</code> optional features.</li>
</ul>
<h2>1.7.0</h2>
<h3>Added</h3>
<ul>
<li>Added optional implementations of <code>bytemuck</code> traits <code>Zeroable</code> and <code>Pod</code> under <code>bytemuck</code> cargo feature. By <a href="https://github.com/charles-r-earp"><code>@​charles-r-earp</code></a>.</li>
