Highlights

Now that rustbuild can bootstrap new hosts for the compiler, there are now nightly compilers for five new platforms, with Cargo following quite soon! These artifacts are all lightly tested, however, and some broader testing would be much appreciated!

If you've got a new host target you'd like to see builds of rustc and Cargo for, ping acrichto on IRC (or @alexcrichton on GitHub) and we'll try to get it set up!
The built-in test runner now has a flag to have quieter output when running tests (one dot per test instead of one line)
A new test suite has been added to the compiler which should help detect regression on a broader range of the ecosystem when landing any change to rust-lang/rust
A number of instances of seemingly infinite recursion in Cargo have been solved through a more optimized traversal of the dependency space when resolving dependencies.
Cargo's style for printing errors has changed to be much more readable.
Cargo will now read the RUSTFLAGS environment variable to pass flags to the compiler for all crates as part of a compilation.
Cargo should now correctly handle concurrent invocations and ensure that global state is not corrupted and builds complete.
The multirust-rs project has now grown the initial rustup implementation which will soon be deployed!
