+Title: This Week in Rust 84
+Date: 2015-06-22
+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:
+safety, concurrency, and speed. This is a weekly summary of its progress and
+community. Want something mentioned? Tweet us at [@ThisWeekInRust](https://twitter.com/ThisWeekInRust) or [send us an
+email](mailto:corey@octayn.net?subject=This%20Week%20in%20Rust%20Suggestion)!
+Want to get involved? [We love
+contributions](https://github.com/rust-lang/rust/wiki/Note-guide-for-new-contributors).
+
+*This Week in Rust* is openly developed [on GitHub](https://github.com/cmr/this-week-in-rust).

+* A summary of the major changes to [Rust by example](http://rustbyexample.com/)
+in the past few months include:
+ - February 15, 2015: The [flow control section](http://rustbyexample.com/flow_control.html)
+was [created](https://github.com/rust-lang/rust-by-example/pull/421) to house
+all flow control operations together.
+ - March 21, 2015: The [formatting section](http://rustbyexample.com/hello/print.html)
+was [revised](https://github.com/rust-lang/rust-by-example/pull/496) so new
+users are immediately confronted with the distinction of `Debug` and `Display`
+and how to deal with them.
+ - May 2, 2015: The table of contents was [reorganized](https://github.com/rust-lang/rust-by-example/pull/561)
+so examples are sorted consistently by categories.
+ - May 23, 2015: The [generics section](http://rustbyexample.com/generics.html) was
+majorly [expanded](https://github.com/rust-lang/rust-by-example/pull/572).

+
+# Breaking Changes
+
+* [Don't panic when stdout doesn't
+ exist](https://github.com/rust-lang/rust/pull/26168). See [RFC
+ 1014](https://github.com/rust-lang/rfcs/blob/master/text/1014-stdout-existential-crisis.md). This
+ is breaking because it changes the behavior of stdio, but in ways
+ that are expected to be less surprising. Considered a bugfix.
+
+# Other Changes
+
+* Thanks to Ashesh Kumar for pointing out that rust-lang.org was not
+ configured with DMARC to prevent spoofing. The misconfiguration has
+ now been corrected.
+* [Optimize implementations of FromIterator and Extend for
+ Vec](https://github.com/rust-lang/rust/pull/22681).
+* [Result - Add an `expect` method that prints a message and the `Err`
+ value](https://github.com/rust-lang/rust/pull/25359).
+* [Break apart global unstable
+ features](https://github.com/rust-lang/rust/pull/26192). Some of the
+ catch-all feature names, `core`, `std_misc`, `collections`, `alloc`,
+ are split into smaller, better-named features.
+* The regex crate received a [rewrite that includes a big performance
+ improvement](https://github.com/rust-lang/regex/pull/91).
+* [Avoid deref/ref cycles for no-op conversions between unsafe
+ pointers](https://github.com/rust-lang/rust/pull/26336). Reduces the
+ amount of IR rustc generates.
+* [Pass fat pointers in two immediate
+ arguments](https://github.com/rust-lang/rust/pull/26411). More
+ codegen improvements from dotdash.
+* [Add FromRow{Fd,Handle,Socket} to os
+ preludes](https://github.com/rust-lang/rust/pull/26413).
+* [Custom Debug impl for
+ io::Error](https://github.com/rust-lang/rust/pull/26416).

+
+# Approved RFCs
+
+* [Update RFC 195 to account for RFC
+ 246](https://github.com/rust-lang/rfcs/pull/865). Just accounting
+ for the `const`/`static` distinction in the associated items RFC.
+* [Clarify cast rules, especially regarding fat
+ pointers](https://github.com/rust-lang/rfcs/pull/1052). Updates RFC
+ 401: coercions.
+* [RFC 1156: Adjust default object
+ bounds](https://github.com/rust-lang/rfcs/blob/master/text/1156-adjust-default-object-bounds.md). This
+ is a stable breaking change (the first) to the default lifetime
+ bounds of trait objects.
+
+# Final Comment Period
+
+Every week the teams announce a 'final comment period' for RFCs which
+are close to reaching a conclusion. Express your opinions now. [This
+week's][fcp] RFCs entering FCP are:
+
+[fcp]: https://github.com/rust-lang/rfcs/pulls?q=is%3Aopen+is%3Apr+label%3Afinal-comment-period
+
+* [Allow closure expressions to expand to a `&` or `&mut` temporary](https://github.com/rust-lang/rfcs/pull/756).
+* [Allow macros in types](https://github.com/rust-lang/rfcs/pull/873).
+* [read_all](https://github.com/rust-lang/rfcs/pull/980).
+* [Add read_into_buf and get_buf to BufRead](https://github.com/rust-lang/rfcs/pull/1015).
+* [Rename `connect` to `join`](https://github.com/rust-lang/rfcs/pull/1102).
+* [Implement `FromIterator` for the unit type](https://github.com/rust-lang/rfcs/pull/1130).
