+Title: This Week in Rust 56
+Date: 2014-11-10
+Category: This Week in Rust
+
+Hello and welcome to another issue of *This Week in Rust*!
+[Rust](http://rust-lang.org) is a systems language pursuing the trifecta:
+safe, concurrent, and fast. This is a weekly summary of its progress and
+community. Want something mentioned? [Send me an
+email!](mailto:[email protected]?subject=This%20Week%20in%20Rust%20Suggestion)
+Want to get involved? [We love
+contributions](https://github.com/mozilla/rust/wiki/Note-guide-for-new-contributors).
+
+# What's cooking on master?
+
+TODO: Update this Monday morning
+
+XXX pull requests were [merged in the last week][1]. Woo!

+## Breaking Changes
+
+TODO: Link to complete breaking changes log
+
+* [Flexible target specification][flex] has finally landed. This makes
+  it much easier to create custom toolchains for unsupported
+  platforms. [RFC][flex-rfc].
+* [Error interoperation][err] improves the ergonomics of error
+  handling when multiple error types are involved. [RFC][err-rfc].
+* There has been a minor breaking change to the [serialization of
+  tuples][tup].
+* Minor [changes to macro interpolation][mac] have resulted the
+  removal the `$foo:matchers` type of `macro_rules!` argument.
+* Socket construction is now more flexibly done through a
+  [`ToSocketAddr`] type.
+* Some changes have been made to the [`BytesContainer`], which is used
+  to construct `Path`s, causing breakage is some cases.
+* The comparision types have been [updated for DST][cmp], resulting in
+  changes to how they are invoked for references to unsized types
+  (i.e. `&str` and `&[T]`).

+## Other Changes
+
+* New [blanket impls] of the unboxed closure types allow them to
+  interoperate.  See
+  [test](https://github.com/rust-lang/rust/blob/master/src/test/run-pass/unboxed-closures-fn-as-fnmut-and-fnonce.rs)
+  [cases])https://github.com/rust-lang/rust/blob/master/src/test/run-pass/unboxed-closures-fnmut-as-fnonce.rs)
+  for examples.
+* impls can now be [defined on trait objects][impltrait].
+* P1start has been [converting][help] compiler messages that provide
+  suggestions from 'notes' to 'help' messages.
+* The ['exceeding_bitshifts'][bitshift] lint (deny by default) catches
+  overlong shifts (which are currently undefined behavior) of static
+  size.
+* Ariel [removed][unsafe-rustc] a bunch of unsafe code from the compiler. Yay!
