  • Cargo
    • Stabilize the config include key. The top-level include config key allows loading additional config files, enabling better organization, sharing, and management of Cargo configurations across projects and environments. docs #16284 — source

  • Compatibility Notes
    • Forbid freely casting lifetime bounds of dyn-types — source
    • Make closure capturing have consistent and correct behaviour around patterns Some finer details of how precise closure captures get affected by pattern matching have been changed. In some cases, this can cause a non-move closure that was previously capturing an entire variable by move, to now capture only part of that variable by move, and other parts by bo… — source
    • Standard library macros are now imported via prelude, not via injected #[macro_use] This will raise an error if macros of the same name are glob imported. For example if a crate defines their own matches macro and then glob imports that, it's now ambiguous whether the custom or standard library matches is meant and an explicit import of the name is re… — source
