+Version 1.33.0 (2019-02-28)
+==========================
+
+Language
+--------
+- [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),
+      Lobster(String),
+      Person(String),
+  }
+
+  fn main() {
+      let state = Creature::Crab("Ferris");
+
+      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 irrefutable pattern destructuring in const functions.][57175]
+- [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 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 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.
+  ```rust
+  use std::io::Read as _;
+
+  // Allowed as there is only one `Read` in the module.
+  pub trait Read {}
+  ```
+- [`extern` functions will now abort by default when panicking.][55982]
+  This was previously undefined behaviour.
+
+Compiler
+--------
+- [You can now set a linker flavor for `rustc` with the `-Clinker-flavor`
+  command line argument.][56351]
+- [The mininum required LLVM version has been bumped to 6.0.][56642]
+- [Added support for the PowerPC64 architecture on FreeBSD.][57615]
+- [The `x86_64-fortanix-unknown-sgx` target support has been upgraded to
+  tier 2 support.][57130] Visit the [platform support][platform-support] page for
+  information on Rust's platform support.
+- [Added support for the `thumbv7neon-linux-androideabi` and
+  `thumbv7neon-unknown-linux-gnueabihf` targets.][56947]
+- [Added support for the `x86_64-unknown-uefi` target.][56769]
+
+Libraries
+---------
+- [The methods `overflowing_{add, sub, mul, shl, shr}` are now `const`
+  functions for all numeric types.][57566]
+- [The methods `rotate_left`, `rotate_right`, and `wrapping_{add, sub, mul, shl, shr}`
+  are now `const` functions for all numeric types.][57105]
+- [The methods `is_positive` and `is_negative` are now `const` functions for
+  all signed numeric types.][57105]
+- [The `get` method for all `NonZero` types is now `const`.][57167]
+- [The methods `count_ones`, `count_zeros`, `leading_zeros`, `trailing_zeros`,
+  `swap_bytes`, `from_be`, `from_le`, `to_be`, `to_le` are now `const` for all
+  numeric types.][57234]
+- [`Ipv4Addr::new` is now a `const` function][57234]

+Compatibility Notes
+-------------------
+- The methods `str::{trim_left, trim_right, trim_left_matches, trim_right_matches}`
+  are now deprecated in the standard library, and their usage will now produce a warning.
+  Please use the `str::{trim_start, trim_end, trim_start_matches, trim_end_matches}`
+  methods instead.
