• RFC 1212: Change all functions dealing with reading "lines" to treat both '\n' and '\r\n'.
• RFC 1242: Policy for rust-lang crates.

• Add the family of [Op]Assign traits to allow overloading assignment operations like a += b.
• Implement raw fat pointer comparisons.
• Expand the std::net module to bind more low-level interfaces.
• Allow a x...y expression to create an inclusive range.
• Add Box::leak to leak Box<T> to &'static mut T.
• Forbid wildcard dependencies on crates.io.

New RFCs

• Add a new ToOpt trait and have bool implement it.
• macro_rules! should support gensym for creating items.
• Implement .drain(range) and .drain() respectively as appropriate on collections.
• UX guidelines for the Rust compiler.
• [TRPLF] Pauseless Concurrent Garbage Collector.

Upcoming Events
