-### Warning about unused tuple-struct fields
-
-If you define a struct containing fields that are never used, rustc will warn
-about the unused fields. Now, in Rust 1.64, you can enable the
-`unused_tuple_struct_fields` lint to get the same warnings about unused fields
-in a tuple struct. In future versions, we plan to make this lint warn by
-default.
-
-Fields of type unit (`()`) do not produce a warning, to make it easier to
-migrate existing code without having to change tuple indices.

-Windows builds of the Rust compiler now use profile-guided optimization,

 ### `rust-analyzer` now available via `rustup`, no longer in preview
 
 Users of `rust-analyzer` can now obtain it via `rustup` on the stable and beta
 channels, not just on nightly.
