+
+- Update to version 1.32.0
+- Language
+  + 2018 edition
+    - You can now use the `?` operator in macro definitions. The `?`
+      operator allows you to specify zero or one repetitions similar to the `*` and
+      `+` operators.
+    - Module paths with no leading keyword like `super`, `self`, or `crate`, will
+      now always resolve to the item (`enum`, `struct`, etc.) available in the
+      module if present, before resolving to a external crate or an item the prelude.
+      E.g.
+      enum Color { Red, Green, Blue }
+      use Color::*;
+  + All editions
+    - You can now match against `PhantomData<T>` types.
+    - You can now match against literals in macros with the `literal`
+      specifier. This will match against a literal of any type.
+      E.g. `1`, `'A'`, `"Hello World"`
+    - Self can now be used as a constructor and pattern for unit and tuple structs. E.g.
+      struct Point(i32, i32);
+
+      impl Point {
+          pub fn new(x: i32, y: i32) -> Self {
+              Self(x, y)
+          }
+
+          pub fn is_origin(&self) -> bool {
+              match self {
+                  Self(0, 0) => true,
+                  _ => false,
+              }
+          }
+      }
+    - Self can also now be used in type definitions. E.g.
+      enum List<T>
+      where
+          Self: PartialOrd<Self> // can write `Self` instead of `List<T>`
+      {
+          Nil,
+          Cons(T, Box<Self>) // likewise here
+      }
+    - You can now mark traits with `#[must_use]`. This provides a warning if
+      a `impl Trait` or `dyn Trait` is returned and unused in the program.
+- Compiler
+  + The default allocator has changed from jemalloc to the default allocator on
+    your system. The compiler itself on Linux & macOS will still use
+    jemalloc, but programs compiled with it will use the system allocator.
+  + Added the `aarch64-pc-windows-msvc` target.
+- Libraries
+  + `PathBuf` now implements `FromStr`.
+  - `Box<[T]>` now implements `FromIterator<T>`.
+  - The `dbg!` macro has been stabilized. This macro enables you to
+    easily debug expressions in your rust program. E.g.
+    let a = 2;
+    let b = dbg!(a * 2) + 1;
+    //      ^-- prints: [src/main.rs:4] a * 2 = 4
+    assert_eq!(b, 5);
+  + The following APIs are now `const` functions and can be used in a
+    `const` context.
+    - `Cell::as_ptr`
+    - `UnsafeCell::get`
+    - `char::is_ascii`
+    - `iter::empty`
