Rust's linter replaces deprecated box patterns with the new deref patterns feature while compiler teams push through three major rollups addressing ambiguity errors, proc-macro refactoring, and TLS safety.

Clippy dropped a significant modernization [1] that replaces box_patterns usage with deref_patterns, tracking against rust-lang/rust#156110 and positioning the linter ahead of the language's evolution. The lint team also fixed two critical internal issues: duplicate diagnostics in min_rust_version_invalid_attr [2] by separating attribute parsing, and an ICE crash [3] when destructuring type aliases in the unnecessary_rest_pattern check. On the compiler side, three rollups landed across 102 commits. The first [4] merged 13 PRs including TLS allocator safety improvements and a new unused_footnote_definition rustdoc lint. The second [5] consolidated 8 changes that merge ambiguity error reporting for better developer clarity on inference variable conflicts. The third [6] removes the target argument from get_proc_macros, simplifying rust-analyzer's proc-macro loading strategy and laying groundwork for future wasm support. Bootstrap also replaced its exit! macro [7] with a proper function to eliminate crate-root ceremony. The dev guide received documentation updates [8] [9] covering feedable query modifiers and attribute link fixes across 5 commits.
