-- [You can now use macros for values in built-in attribute macros.][83366]
- While a seemingly minor addition on its own, this enables a lot of
- powerful functionality when combined correctly. Most notably you can
- now include external documentation in your crate by writing the following.
+- [You can now use macros for values in some built-in attributes.][83366]
+ This primarily allows you to call macros within the `#[doc]` attribute. For
+ example, to include external documentation in your crate, you can now write
+ the following:
```rust
#![doc = include_str!("README.md")]
```
- You can also use this to include auto-generated modules:
- ```rust
- #[path = concat!(env!("OUT_DIR"), "/generated.rs")]
- mod generated;
- ```
- [You can now cast between unsized slice types (and types which contain
unsized slices) in `const fn`.][85078]
- [Improved debugger output for enums on Windows MSVC platforms.][85292]
- [Added tier 3\* support for `bpfel-unknown-none`
and `bpfeb-unknown-none`.][79608]
+- [`-Zmutable-noalias=yes`][82834] is enabled by default when using LLVM 12 or above.
\* Refer to Rust's [platform support page][platform-support-doc] for more
