+Version 1.36.0 (2019-07-04)
+==========================
+
+Language
+--------
+- [Non-Lexical Lifetimes are now enabled on the 2015 edition.][59114]
+- [The order of traits in trait objects no longer affects the semantics of that
+  object.][59445] e.g. `dyn Send + fmt::Debug` is now equivalent to
+  `dyn fmt::Debug + Send`, where this was previously not the case.
+
+Libraries
+---------
+- [`HashMap`'s implementation has been replaced with `hashbrown::HashMap` implementation.][58623]
+- [`TryFromSliceError` now implements `From<Infallible>`.][60318]
+- [`mem::needs_drop` is now available as a const fn.][60364]
+- [`alloc::Layout::from_size_align_unchecked` is now available as a const fn.][60370]
+- [`String` now implements `BorrowMut<str>`.][60404]
+- [`io::Cursor` now implements `Default`.][60234]
+- [Both `NonNull::{dangling, cast}` are now const fns.][60244]
+- [The `alloc` crate is now stable.][59675] `alloc` allows you to use a subset
+  of `std` (e.g. `Vec`, `Box`, `Arc`) in `#![no_std]` environments if the
+  environment has access to heap memory allocation.
+- [`String` now implements `From<&String>`.][59825]
+- [You can now pass multiple arguments to the `dbg!` macro.][59826] `dbg!` will
+  return a tuple of each argument when there is multiple arguments.
+- [`Result::{is_err, is_ok}` are now `#[must_use]` and will produce a warning if
+  not used.][59648]
+
+Stabilized APIs

+-----
+- [Cargo will now produce an error if you attempt to use the name of a required dependency as a feature.][cargo/6860]
+- [You can now pass the `--offline` flag to run cargo without accessing the network.][cargo/6934]
+
+You can find further change's in [Cargo's 1.36.0 release notes][cargo-1-36-0].
+
+Clippy
+------
+There have been numerous additions and fixes to clippy, see [Clippy's 1.36.0 release notes][clippy-1-36-0] for more details.

+
+Compatibility Notes
+-------------------
+- With the stabilisation of `mem::MaybeUninit`, `mem::uninitialized` use is no
+  longer recommended, and will be deprecated in 1.38.0.

-/// `FnBox` is deprecated and will be removed.
-/// `Box<dyn FnOnce()>` can be called directly, since Rust 1.35.0.
-///
-/// `FnBox` is a version of the `FnOnce` intended for use with boxed
-/// closure objects. The idea was that where one would normally store a
-/// `Box<dyn FnOnce()>` in a data structure, you whould use
-/// `Box<dyn FnBox()>`. The two traits behave essentially the same, except
-/// that a `FnBox` closure can only be called if it is boxed.
-///
-/// # Examples
-///
-/// Here is a snippet of code which creates a hashmap full of boxed
-/// once closures and then removes them one by one, calling each
-/// closure as it is removed. Note that the type of the closures
-/// stored in the map is `Box<dyn FnBox() -> i32>` and not `Box<dyn FnOnce()
-/// -> i32>`.
-///
-/// ```
-/// #![feature(fnbox)]
-/// #![allow(deprecated)]
-///
-/// use std::boxed::FnBox;
-/// use std::collections::HashMap;
-///
-/// fn make_map() -> HashMap<i32, Box<dyn FnBox() -> i32>> {
-///     let mut map: HashMap<i32, Box<dyn FnBox() -> i32>> = HashMap::new();
-///     map.insert(1, Box::new(|| 22));
-///     map.insert(2, Box::new(|| 44));
-///     map

-/// fn main() {

-///         let f = map.remove(&i).unwrap();
-///         assert_eq!(f(), i * 22);
-///     }
-/// }
-/// ```
-///
-/// In Rust 1.35.0 or later, use `FnOnce`, `FnMut`, or `Fn` instead:
-///
-/// ```
-/// use std::collections::HashMap;
-///
-/// fn make_map() -> HashMap<i32, Box<dyn FnOnce() -> i32>> {
