- [The inclusive range syntax e.g. `for x in 0..=10` is now stable.][47813]
- [Stablise `'_`. The underscore lifetime can be used anywhere where a
lifetime can be elided.][49458]
-- [`impl Trait` is now stable allowing you to have abstract
- return types.][49255] e.g. `fn foo() -> impl Iterator<Item=u8>` or
+- [`impl Trait` is now stable allowing you to have abstract types in returns

- [Pattern matching will now automatically apply dereferences.][49394]
- [128-bit integers in the form of `u128` and `i128` are now stable.][49101]
- [`main` can now return `Result<(), E: Debug>`][49162] in addition to `()`.
- [A lot of operations are now available in a const context.][46882] E.g. You
- can now index into constant arrays, reference and deference into constants,
+ can now index into constant arrays, reference and dereference into constants,
and use Tuple struct constructors.
- [Fixed entry slice patterns are now stable.][48516] e.g.
```rust
- [`".e0"` will now no longer parse as `0.0` and will instead cause
an error.][48235]
- [Removed hoedown from rustdoc.][48274]
