Hello and welcome to the lucky 13th issue of This Week in Rust. Graydon has stepped down as project lead. It seems to be a bit ambiguous whether he'll still be working on the project. Brian (brson) will be taking over as lead.

What's cooking in master?

Breaking Changes

• Some functions have been removed from std::str.
• The unit test framework now uses RUST_TEST_TASKS instead of RUST_THREADS.
• typeof is now a reserved keyword.
• offset_inbounds has been removed.
• Some edge cases with writing to a borrowed &mut have been closed, rejecting more incorrect programs.
