+Version 1.39.0 (2019-11-07)
+===========================
+
+Language
+--------
+- [You can now create `async` functions and blocks with `async fn`, `async move {}`, and
+  `async {}` respectively, and you can now call `.await` on async expressions.][63209]
+- [You can now use certain attributes on function, closure, and function pointer
+  parameters.][64010] These attributes include `cfg`, `cfg_attr`, `allow`, `warn`,
+  `deny`, `forbid` as well as inert helper attributes used by procedural macro
+  attributes applied to items. e.g.
+  ```rust
+  fn len(
+      #[cfg(windows)] slice: &[u16],
+      #[cfg(not(windows))] slice: &[u8],
+  ) -> usize {
+      slice.len()
+  }
+  ```
+- [You can now take shared references to bind-by-move patterns in the `if` guards
+  of `match` arms.][63118] e.g.
+  ```rust
+  fn main() {
+      let array: Box<[u8; 4]> = Box::new([1, 2, 3, 4]);
+
+      match array {
+          nums
+  //      ---- `nums` is bound by move.
+              if nums.iter().sum::<u8>() == 10
+  //                 ^------ `.iter()` implicitly takes a reference to `nums`.
+          => {
+              drop(nums);
+  //          ----------- Legal as `nums` was bound by move and so we have ownership.
+          }
+          _ => unreachable!(),
+      }
+  }
+  ```
+
+
+
+Compiler
+--------
+- [Added tier 3\* support for the `i686-unknown-uefi` target.][64334]
+- [Added tier 3 support for the `sparc64-unknown-openbsd` target.][63595]
+- [rustc will now trim code snippets in diagnostics to fit in your terminal.][63402]
+  **Note** Cargo currently doesn't use this feature. Refer to
+  [cargo#7315][cargo/7315] to track this feature's progress.
+- [You can now pass `--show-output` argument to test binaries to print the
+  output of successful tests.][62600]
+
+
+\* Refer to Rust's [platform support page][forge-platform-support] for more
+information on Rust's tiered platform support.
+
+Libraries
+---------
+- [`Vec::new` and `String::new` are now `const` functions.][64028]
+- [`LinkedList::new` is now a `const` function.][63684]
+- [`str::len`, `[T]::len` and `str::as_bytes` are now `const` functions.][63770]
+- [The `abs`, `wrapping_abs`, and `overflowing_abs` numeric functions are
+  now `const`.][63786]
+
+Stabilized APIs
+---------------
+- [`Pin::into_inner`]
+- [`Instant::checked_duration_since`]
+- [`Instant::saturating_duration_since`]
+
+Cargo
+-----
+- [You can now publish git dependencies if supplied with a `version`.][cargo/7237]
+- [The `--all` flag has been renamed to `--workspace`.][cargo/7241] Using
+  `--all` is now deprecated.
+
+Misc
+----
+- [You can now pass `-Clinker` to rustdoc to control the linker used
+  for compiling doctests.][63834]
+
+Compatibility Notes
+-------------------
+- [Code that was previously accepted by the old borrow checker, but rejected by
+  the NLL borrow checker is now a hard error in Rust 2018.][63565] This was
+  previously a warning, and will also become a hard error in the Rust 2015
+  edition in the 1.40.0 release.
+- [`rustdoc` now requires `rustc` to be installed and in the same directory to
+  run tests.][63827] This should improve performance when running a large
+  amount of doctests.
+- [The `try!` macro will now issue a deprecation warning.][62672] It is
+  recommended to use the `?` operator instead.
+- [`asinh(-0.0)` now correctly returns `-0.0`.][63698] Previously this
+  returned `0.0`.
