+
+Cargo
+-----
+
+* [Disallow specifying features of transitive deps]
+  (https://github.com/rust-lang/cargo/pull/2821)
+* [Add color support for Windows consoles]
+  (https://github.com/rust-lang/cargo/pull/2804)
+* [Fix `harness = false` on `[lib]` sections]
+  (https://github.com/rust-lang/cargo/pull/2795)
+* [Don't panic when `links` contains a '.']
+  (https://github.com/rust-lang/cargo/pull/2787)
+* [Build scripts can emit warnings]
+  (https://github.com/rust-lang/cargo/pull/2630),
+  and `-vv` prints warnings for all crates.
+* [Ignore file locks on OS X NFS mounts]
+  (https://github.com/rust-lang/cargo/pull/2720)
+* [Don't warn about `package.metadata` keys]
+  (https://github.com/rust-lang/cargo/pull/2668).
+  This provides room for expansion by arbitrary tools.
+* [Add support for cdylib crate types]
+  (https://github.com/rust-lang/cargo/pull/2741)
+* [Prevent publishing crates when files are dirty]
+  (https://github.com/rust-lang/cargo/pull/2781)
+* [Don't fetch all crates on clean]
+  (https://github.com/rust-lang/cargo/pull/2704)
+* [Propagate --color option to rustc]
+  (https://github.com/rust-lang/cargo/pull/2779)
+* [Fix `cargo doc --open` on Windows]

+* [Configure colors of stderr as well as stdout]
+  (https://github.com/rust-lang/cargo/pull/2739)
+
+Performance
+-----------
+
+* [Caching projections speeds up type check dramatically for some
+  workloads]
+  (https://github.com/rust-lang/rust/pull/33816)
+* [The default `HashMap` hasher is SipHash 1-3 instead of SipHash 2-4]
+  (https://github.com/rust-lang/rust/pull/33940)
+  This hasher is faster, but is believed to provide sufficient
+  protection from collision attacks.
+* [Comparison of `Ipv4Addr` is 10x faster]
+  (https://github.com/rust-lang/rust/pull/33891)
+

+
+Tooling
+-------
+
+* [rustc is better at finding the MSVC toolchain]
+  (https://github.com/rust-lang/rust/pull/34492)

+  shims and glue, as it does for all other functions]
+  (https://github.com/rust-lang/rust/pull/33909)
+* [rust-lldb warns about unsupported versions of LLDB]
+  (https://github.com/rust-lang/rust/pull/34646)
+* Many more errors have been given error codes and extended
+  explanations
+* API documentation continues to be improved, with many new examples
+
+Misc
+----
+
+* [rustc no longer hangs when dependencies recursively re-export
+  submodules]
+  (https://github.com/rust-lang/rust/pull/34542)
+* [rustc requires LLVM 3.7+]
+  (https://github.com/rust-lang/rust/pull/34104)
+* [The 'How Safe and Unsafe Interact' chapter of The Rustonomicon was
+  rewritten]
+  (https://github.com/rust-lang/rust/pull/33895)
+* [rustc support 16-bit pointer sizes]
+  (https://github.com/rust-lang/rust/pull/33460).
+  No targets use this yet, but it works toward AVR support.
+
+Compatibility Notes
+-------------------
+
+* [`const`s and `static`s may not have unsized types]
+  (https://github.com/rust-lang/rust/pull/34443)
+* [The new follow-set rules that place restrictions on `macro_rules!`
+  in order to ensure syntax forward-compatibility have been enabled]
+  (https://github.com/rust-lang/rust/pull/33982)
+  This was an [ammendment to RFC 550]
+  (https://github.com/rust-lang/rfcs/pull/1384),
+  and has been a warning since 1.10.
+* [`cfg` attribute process has been refactored to fix various bugs]
+  (https://github.com/rust-lang/rust/pull/33706).
+  This causes breakage in some corner cases.
