Approved RFC's

  • 503: prelude stabilization. Removes a ton of stuff from the prelude, and moves what remains to a std::prelude::v1 module.
  • 474: path reform. Tightens up the Path API, and makes some changes around their internal representation.
  • 504: Show stabilization. Splits Show into Show and String, with Show being tied to the re-introduced {:?} format string specifier for debugging purposes.
  • 453: macro reform. Tightens up how macro import/export "works", and solves the "curious inner module" problem with a $crate meta-variable.
  • 486: std::ascii reform. Removes the Ascii newtype and implements the old functionality on various forms of arrays of u8 instead.
  • 509: collections reform part 2. Finalizes the fate of std::collections, marking some as stable and moving some to the external collect-rs crate.
  • 520: new array repeat syntax. Due to an ambiguity with range notation, the fixed-length array syntax has changed to [T; N] for the type and [expr; N] for the constructor.
  • 522: Allow Self to be used in impls. As it sounds. Reduces verbosity.
