 - [You can now use the `cfg(target_vendor)` attribute.][57465] E.g.
   `#[cfg(target_vendor="linux")] fn main() { println!("Hello Linux!"); }`
+- [Integer patterns such as in a match expression can now be exhaustive.][56362]
+  E.g. You can have match statement on a `u8` that covers `0..=255` and
+  you would no longer be required to have a `_ => unreachable!()` case. 
 - [You can now have multiple patterns in `if let` and `while let`
   expressions.][57532] You can do this with the same syntax as a `match`
   expression. E.g.
   ```rust
   enum Creature {
-    Crab(String),
-    Person(String),
+      Crab(String),
+      Lobster(String),
+      Person(String),
   }
 
   fn main() {
-    let state = Creature::Crab("Ferris");
+      let state = Creature::Crab("Ferris");
 
-    if let Creature::Crab(name) | Creature::Person(name) = state {
-      println!("This creature's name is: {}", name);
-    }
+      if let Creature::Crab(name) | Creature::Person(name) = state {
+        println!("This creature's name is: {}", name);
+      }
   }
   ```
 - [You can now have irrefutable `if let` and `while let` patterns.][57535] Using
   this feature will by default produce a warning as this behaviour can be
   unintuitive. E.g. `if let _ = 5 {}`
 - [You can now use `let` bindings, assignments, expression statements, and pattern destructuring in
   const functions.][57175]
-- [You can now specify multiple attributes in a `cfg_attr` attribute.][57332]
-  E.g. `#[cfg_attr(all(), must_use, optimize)]`
-- [You can now specify a specific alignment with the `#[repr(packed)]`
-  attribute.][57049] E.g. `#[repr(packed(2))] struct Foo(i16, i32);` is a struct
-  with an alignment of 2 bytes and a size of 6 bytes.
-- [You can now call unsafe constant functions.][57067] E.g.
+- [You can now call unsafe const functions.][57067] E.g.
   ```rust
   const unsafe fn foo() -> i32 { 5 }
   const fn bar() -> i32 {
     unsafe { foo() }
   }
   ```

 - [You can now import an item from a module as an `_`.][56303] This allows you to
   import a trait's impls, and not have the name in the namespace. E.g.

+Compatibility Notes
+-------------------
+- The functions `str::{trim_left, trim_right, trim_left_matches, trim_right_matches}`
+  are now offically deprecated, and their usage will now produce a warning. Please use the
