The Rust compiler landed a massive 20-PR rollup overnight, and rustfmt corrected a brace-placement bug that affects Style Edition 2027.

The Rust compiler merged a 20-PR rollup [1] that includes support for 16-bit proc-macro targets [2], a fix for the `default impl` ordering regression in the new solver [4], and a move to use the attribute parser for `deprecated` checking [3]. At the same time, rustfmt shipped a fix that changes brace placement for multiline control flow in Style Edition 2027, aligning it with the Rust Style Guide, while leaving 2024 behavior unchanged [5]. The rust-forge and rustc-dev-guide teams are consolidating contributor docs, moving content that's "applicable to the whole project, not just to the compiler" from the dev-guide into Forge [6], and rust-forge is renaming its default branch to `main` [7]. On the infrastructure side, rustfmt replaced the archived `actions/upload-release-asset` with the gh CLI in CI to keep releases working [8]. Nothing else moved the needle: the crates.io index saw routine crate creates and updates [9].
