-Library authors should take the MSRV-aware resolver into account when deciding their policy on adopting new Rust toolchain features. Previously, a library adopting features from a new Rust toolchain would force downstream users of that library who have an older Rust version to either upgrade their toolchain or manually select an old version of the library compatible with their toolchain (and avoid running `cargo update`). Now, those users will be able to automatically use older library versions compatible with their older toolchain. In the future, we expect this to provide more flexibility for library authors to select their preferred support strategy for Rust versions, without worrying about users on older toolchains.

 The new resolver will be enabled by default with the 2024 edition (expected to
 stabilize in 1.85), but can be enabled as of 1.84 by setting
