<blockquote>
<h2>v2.0.0</h2>
<h2>What's Changed</h2>
<ul>
<li>
<p>Use <code>CARGO_BUILD_WARNINGS</code> for enforcing warning free
compilations (<a
href="https://redirect.github.com/actions-rust-lang/setup-rust-toolchain/issues/98">#98</a>)
This is a new variable supported by cargo 1.97+ <a
href="https://blog.rust-lang.org/2026/07/09/Rust-1.97.0/#cargo-support-for-denying-warnings">and
sets the <code>build.warnings</code> config</a>.
It allows removing the <code>RUSTFLAGS=&quot;-D warnings&quot;</code>
default, which will improve compatibility with
<code>target.*.rustflags</code> and <code>.cargo/config.toml</code>
files.</p>
<p>This adds a new <code>build-warnings</code> input to configure the
value for the <code>build.warnings</code> config.</p>
</li>
<li>
<p>Add error matcher for Rust panics
This will highlight the location of the panic location during tests.</p>
</li>
<li>
<p>Reuse output of <code>rustc --version --verbose</code> calls (<a
href="https://redirect.github.com/actions-rust-lang/setup-rust-toolchain/issues/103">#103</a>

<h2>[1.17.0] - 2026-06-25</h2>
<ul>
<li>Add new parameter <code>cache-targets</code> that is propagated to
<code>Swatinem/rust-cache</code> as <code>cache-targets</code> (<a
href="https://redirect.github.com/actions-rust-lang/setup-rust-toolchain/issues/84">#84</a>).
This allows disabling caching of the workspace <code>target</code>
directory, e.g. when using <code>sccache</code>, while keeping the rest
of the cache enabled.</li>
</ul>
<h2>[1.16.1] - 2026-05-08</h2>
<ul>
<li>Renamed internally used variable to avoid clashes with globally
existing variables.
This fixes the interference of the TOOLCHAIN variable as reported in <a
href="https://redirect.github.com/actions-rust-lang/setup-rust-toolchain/issues/91">#91</a>.</li>
</ul>
<h2>[1.16.0] - 2026-04-13</h2>
<ul>
<li>Add new parameter <code>cache-save-if</code> that is propagated to
<code>Swatinem/rust-cache</code> as <code>save-if</code> (<a
href="https://redirect.github.com/actions-rust-lang/setup-rust-toolchain/issues/90">#90</a>
by <a
href="https://github.com/ChanTsune"><code>@​ChanTsune</code></a>)</li>
</ul>
<h2>[1.15.4] - 2026-03-15</h2>
<ul>
<li>Bump Swatinem/rust-cache from 2.8.2 to 2.9.1 (<a
href="https://redirect.github.com/actions-rust-lang/setup-rust-toolchain/issues/87">#87</a>
by <a
href="https://github.com/hyperfinitism"><code>@​hyperfinitism</code></a>)
This gets rid of the warnings about Node.js 20.</li>
</ul>
<h2>[1.15.3] - 2026-03-01</h2>
<ul>
<li>Bump Swatinem/rust-cache from 2.8.1 to 2.8.2</li>
</ul>
<h2>[1.15.2] - 2025-10-04</h2>
<ul>
<li>Fix: Run the version detection steps in the selected
<code>rust-src-dir</code> directory.
This should enable the version selection even without a default
toolchain installed.
Fixes <a
href="https://redirect.github.com/actions-rust-lang/setup-rust-toolchain/issues/74">#74</a>.</li>
</ul>
