+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]
+
+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]

+Version 1.27.1 (2018-07-10)
+===========================
+
+Security Notes
+--------------
+
+- rustdoc would execute plugins in the /tmp/rustdoc/plugins directory
+ when running, which enabled executing code as some other user on a
+ given machine. This release fixes that vulnerability; you can read
+ more about this on the [blog][rustdoc-sec]. The associated CVE is [CVE-2018-1000622].
+
+ Thank you to Red Hat for responsibily disclosing this vulnerability to us.
