+Version 1.25.0 (2018-03-29)
+==========================
+
+Language
+--------
+- [Stabilised `#[repr(align(x))]`.][47006] [RFC 1358]
+- [You can now use nested groups of imports.][47948]
+  e.g. `use std::{fs::File, io::Read, path::{Path, PathBuf}};`
+- [You can now have `|` at the start of a match arm.][47947] e.g.
+```rust
+enum Foo { A, B, C }
+
+fn main() {
+    let x = Foo::A;
+    match x {
+        | Foo::A
+        | Foo::B => println!("AB"),
+        | Foo::C => println!("C"),
+    }
+}
+```
+
+Compiler
+--------
+- [Upgraded to LLVM 6.][47828]
+- [Added `-C lto=val` option.][47521]
+- [Added `i586-unknown-linux-musl` target][47282]
+
+Libraries
+---------
+- [Impl Send for `process::Command` on Unix.][47760]
+- [Impl PartialEq and Eq for `ParseCharError`.][47790]
+- [`UnsafeCell::into_inner` is now safe.][47204]
+- [Implement libstd for CloudABI.][47268]
+- [`Float::{from_bits, to_bits}` is now available in libcore.][46931]
+- [Implement `AsRef<Path>` for Component][46985]
+- [Implemented `Write` for `Cursor<&mut Vec<u8>>`][46830]
+- [Moved `Duration` to libcore.][46666]
+
+Stabilized APIs
+---------------
+- [`Location::column`]
+- [`ptr::NonNull`]
+
+The following functions can now be used in a constant expression.
+eg. `static MINUTE: Duration = Duration::from_secs(60);`
+- [`Duration::new`][47300]
+- [`Duration::from_secs`][47300]
+- [`Duration::from_millis`][47300]
+
+Cargo
+-----
+- [`cargo new` no longer removes `rust` or `rs` prefixs/suffixs.][cargo/5013]
+- [`cargo new` now defaults to creating a binary crate, instead of a
+  library crate.][cargo/5029]
+
+Misc
+----
+- [Rust by example is now shipped with new releases][46196]
+
+Compatibility Notes
+-------------------
+- [Deprecated `net::lookup_host`.][47510]
+- [`rustdoc` has switched to pulldown as the default markdown renderer.][47398]
+- The borrow checker was sometimes incorrectly permitting overlapping borrows
+  around indexing operations (see [#47349][47349]). This has been fixed (which also
+  enabled some correct code that used to cause errors (e.g. [#33903][33903] and [#46095][46095]).
+- [Removed deprecated unstable attribute `#[simd]`.][47251]
