Looks good to me after the small correction! |

Don't silently ignore invalid data in target spec This is technically a breaking change, but only because invalid data was previously silently being ignored.

Version 1.29.0 (2018-09-13)
==========================
Compiler
--------
- [Bumped minimum LLVM version to 5.0.][51899]
- [Added `powerpc64le-unknown-linux-musl` target.][51619]
- [Added `aarch64-unknown-hermit` and `x86_64-unknown-hermit` targets.][52861]
Libraries
---------
- [`Once::call_once` now no longer requires `Once` to be `'static`.][52239]
- [`BuildHasherDefault` now implements `PartialEq` and `Eq`.][52402]
- [`Box<CStr>`, `Box<OsStr>`, and `Box<Path>` now implement `Clone`.][51912]
- [Implemented `PartialEq<&str>` for `OsString` and `PartialEq<OsString>`
for `&str`.][51178]
- [`Cell<T>` now allows `T` to be unsized.][50494]
- [`SocketAddr` is now stable on Redox.][52656]
Stabilized APIs
---------------
- [`Arc::downcast`]
- [`Iterator::flatten`]
- [`Rc::downcast`]
Cargo
-----
- [Cargo can silently fix some bad lockfiles ][cargo/5831] You can use
`--locked` to disable this behaviour.
- [`cargo-install` will now allow you to cross compile an install
using `--target`][cargo/5614]
- [Added the `cargo-fix` subcommand to automatically move project code from
2015 edition to 2018.][cargo/5723]
Misc
----
- [`rustdoc` now has the `--cap-lints` option which demotes all lints above
the specified level to that level.][52354] For example `--cap-lints warn`
will demote `deny` and `forbid` lints to `warn`.
- [`rustc` and `rustdoc` will now have the exit code of `1` if compilation
fails, and `101` if there is a panic.][52197]
- [A preview of clippy has been made available through rustup.][51122]
You can install the preview with `rustup component add clippy-preview`
Compatibility Notes
-------------------
- [`str::{slice_unchecked, slice_unchecked_mut}` are now deprecated.][51807]
Use `str::get_unchecked(begin..end)` instead.
- [`std::env::home_dir` is now deprecated for its unintuitive behaviour.][51656]
Consider using the `home_dir` function from
https://crates.io/crates/dirs instead.
- [`rustc` will no longer silently ignore invalid data in target spec.][52330]
