<blockquote>
<h2>tracing-core 0.1.26</h2>
<p>This release adds a <code>Value</code> implementation for <code>Box&lt;T: Value&gt;</code> to allow
recording boxed values more conveniently. In particular, this should improve
the ergonomics of the implementations for <code>dyn std::error::Error</code> trait objects,
including those added in <a href="https://github.com/tokio-rs/tracing/releases/tag/tracing-core-0.1.25">v0.1.25</a>.</p>
<h3>Added</h3>
<ul>
<li><code>Value</code> implementation for <code>Box&lt;T&gt; where T: Value</code> (<a href="https://github-redirect.dependabot.com/tokio-rs/tracing/issues/2071">#2071</a>)</li>
</ul>
<h3>Fixed</h3>
<ul>
<li>Broken documentation links (<a href="https://github-redirect.dependabot.com/tokio-rs/tracing/issues/2068">#2068</a>)</li>
