+Version 1.37.0 (2019-08-15)
+==========================
+
+Language
+--------
+- `#[must_use]` will now warn if the type is contained in a [tuple][61100],
+  [`Box`][62228], or an [array][62235] and unused.
+- [You can now use the `cfg` and `cfg_attr` attributes on
+  generic parameters.][61547]
+- [You can now use enum variants through type alias.][61682] e.g. You can
+  write the following:
+  ```rust
+  type MyOption = Option<u8>;
+
+  fn increment_or_zero(x: MyOption) -> u8 {
+      match x {
+          MyOption::Some(y) => y + 1,
+          MyOption::None => 0,
+      }
+  }
+  ```
+- [You can now use `_` as an identifier for consts.][61347] e.g. You can write
+  `const _: u32 = 5;`.
+- [You can now use `#[repr(align(X)]` on enums.][61229]
+- [The  `?`/_"Kleene"_ macro operator is now available in the
+  2015 edition.][60932]
+
+Compiler
+--------
+- [You can now enable Profile-Guided Optimization with the `-C profile-generate`
+  and `-C profile-use` flags.][61268] For more information on how to use profile
+  guided optimization, please refer to the [rustc book][rustc-book-pgo].
+- [The `rust-lldb` wrapper script should now work again.][61827]
+
+Libraries
+---------
+- [`mem::MaybeUninit<T>` is now ABI-compatible with `T`.][61802]
+
+Stabilized APIs
+---------------
+- [`BufReader::buffer`]
+- [`BufWriter::buffer`]
+- [`Cell::from_mut`]
+- [`Cell<[T]>::as_slice_of_cells`][`Cell<slice>::as_slice_of_cells`]
+- [`DoubleEndedIterator::nth_back`]
+- [`Option::xor`]
+- [`Wrapping::reverse_bits`]
+- [`i128::reverse_bits`]
+- [`i16::reverse_bits`]
+- [`i32::reverse_bits`]
+- [`i64::reverse_bits`]
+- [`i8::reverse_bits`]
+- [`isize::reverse_bits`]

+
+Cargo
+-----
+- [`Cargo.lock` files are now included by default when publishing executable crates
+  with executables.][cargo/7026]
+- [You can now specify `default-run="foo"` in `[package]` to specify the
+  default executable to use for `cargo run`.][cargo/7056]
+
+Misc
+----
+
+Compatibility Notes
+-------------------
+- [Using `...` for inclusive range patterns will now warn by default.][61342]
+  Please transition your code to using the `..=` syntax for inclusive
+  ranges instead.
+- [Using a trait object without the `dyn` will now warn by default.][61203]
+  Please transition your code to use `dyn Trait` for trait objects instead.
