<li>closure field capturing: don't depend on alignment of packed fields</li>
<li>Enable MIR-based drop-tracking for async blocks</li>
<li>Stabilize impl_trait_projections</li>
</ul>
<h2>Compiler</h2>
<ul>
<li>stabilize combining +bundle and +whole-archive link modifiers</li>
<li>Stabilize PATH option for --print KIND=PATH</li>
<li>Enable ASAN/LSAN/TSAN for *-apple-ios-macabi</li>

<li>impl TryFrom<char> for u16</li>
<li>Stabilize io_error_other feature</li>
<li>Stabilize the Saturating type</li>
<li>Stabilize const_transmute_copy</li>
</ul>
<h2>Stabilized APIs</h2>
<ul>
<li>core::num::Saturating</li>
<li>impl From<io::Stdout> for std::process::Stdio</li>
<li>impl From<io::Stderr> for std::process::Stdio</li>
