Version 1.21.0 (2017-10-12)
==========================

Language
--------
- [Relaxed path syntax. You can now add type parameters to values][43540]
Example: `struct Foo<T>(T); let bar = Foo::<u8>(0);`.

Foo::<u8>(0) was always possible, what #43540 does is permitting (sometimes unnecessary) :: before < in all paths, including paths passed to macros.
Previously:

my_macro!(Vec<i32>::new); // OK
my_macro!(Vec::<i32>::new); // ERROR

Now:

my_macro!(Vec<i32>::new); // OK
my_macro!(Vec::<i32>::new); // OK too


Compiler
--------
- [Upgraded jemalloc to 4.5.0][43911]
- [Enabled unwinding panics on Redox][43917]

Libraries
---------
- [Generate builtin impls for `Clone` for `[T: N]` where `N` is between 0

It's more than this. Clone is now implemented for all arrays with T: Clone, all tuples with every member being Clone and all function pointers.

- [`Stdin`, `Stdout`, and `Stderr` now implement `AsRawFd`.][43459]
- [`Rc` and `Arc` now implement `From<&[T]> where T: Clone`, `From<str>`,
`From<String>`, `From<Box<T>> where T: ?Sized`, and `From<Vec<T>>`.][42565]

Stabilized APIs
---------------

Cargo
-----
- [You can now call `cargo install` with multiple package names][cargo/4216]
- [Cargo commands inside a virtual workspace will now implicitly
pass `--all`][cargo/4335]

Misc
----
- [Cargo docs are moving][43916]
to [doc.rust-lang.org/cargo](//doc.rust-lang.org/cargo)
- [The rustdoc book is now available][43863]
at [doc.rust-lang.org/rustdoc](//doc.rust-lang.org/rustdoc)

Compatibility Notes
-------------------
- [Remove the trait selection impl in method::probe][43880] This may cause
breakage in subtyping corner cases.

Is there any breakage examples?

BTW "trait selection impl in method::probe" sounds too technical for readers.

It definitely is I just couldn't think of anything better. @arielb1 would you know a better explanation and example?

@Aaronepower: Maybe summarize or just link to #44224 (comment) ?

- [make JSON error's byte position start at top of file.][42973] Was previously
relative to the `CodeMap` which required unstable code.

Release note readers shouldn't need to think about named internal implementation details like CodeMap, and I'm not sure where "which required unstable code" is coming from.

Maybe something like "was previously relative to a concatenation of files in a crate"?? (I don't actually know how the compiler determines which files go in a CodeMap—and neither does typical consumer of error-message JSON, which is why we fixed this).
