| 74 | + <p>The Rust team has published a new point release of Rust, 1.68.1. Rust is a |
| 75 | +programming language that is empowering everyone to build reliable and |
| 76 | +efficient software.</p> |
| 77 | +<p>If you have a previous version of Rust installed via rustup, you can get 1.68.1 with:</p> |
| 78 | +<pre><code>rustup update stable |
| 79 | +</code></pre> |
| 80 | +<p>If you don't have it already, you can <a href="https://www.rust-lang.org/install.html">get <code>rustup</code></a> |
| 81 | +from the appropriate page on our website, and check out the |
| 82 | +<a href="https://github.com/rust-lang/rust/blob/stable/RELEASES.md#version-1681-2023-03-23">detailed release notes for 1.68.1</a> on GitHub.</p> |
| 83 | +<h2><a href="#whats-in-1681-stable" aria-hidden="true" class="anchor" id="whats-in-1681-stable"></a>What's in 1.68.1 stable</h2> |
| 84 | +<p>Rust 1.68.1 stable primarily contains a change to how Rust's CI builds the |
| 85 | +Windows MSVC compiler, no longer enabling LTO for the Rust code. This led to a |
| 86 | +<a href="https://github.com/rust-lang/rust/issues/109067">miscompilation</a> that the Rust |
| 87 | +team is debugging, but in the meantime we're reverting the change to enable |
| 88 | +LTO.</p> |
| 89 | +<p>This is currently believed to have no effect on wider usage of ThinLTO. The |
| 90 | +Rust compiler used an unstable flag as part of the build process to enable |
| 91 | +ThinLTO despite compiling to a dylib.</p> |
| 92 | +<p>There are a few other regression fixes included in the release:</p> |
| 93 | +<ul> |
| 94 | +<li><a href="https://github.com/rust-lang/rust/pull/109111/">Fix building the compiler with <code>--enable-local-rust</code></a></li> |
| 95 | +<li><a href="https://github.com/rust-lang/rust/pull/109156">Treat <code>$prefix-clang</code> as <code>clang</code> in linker detection code</a></li> |
| 96 | +<li><a href="https://github.com/rust-lang/rust/pull/108162">Fix a panic in the compiler</a></li> |
| 97 | +</ul> |
