There are some new feature proposals to talk about for Fedora 25, which will be officially released around November.
The latest self-contained change that is proposed for Fedora 25 is Rust compiler support. In particular, the hope is to package up the LLVM-based Rust compiler and its Cargo build system and offer them via the main Fedora repository. The current plan is for packaging Rust 1.10 and Cargo 0.11.
