// Prints "abcdefghijklmnopqrstuvwxyz"

- [`OsString` now implements `FromStr`.][71662]
-- [The `saturating_neg` method as been added to all signed integer primitive
+- [The `saturating_neg` method has been added to all signed integer primitive
types, and the `saturating_abs` method has been added for all integer
primitive types.][71886]
- [`Arc<T>`, `Rc<T>` now implement `From<Cow<'_, T>>`, and `Box` now
Cargo
-----
+- [Cargo uses the `embed-bitcode` flag to optimize disk usage and build
+ time.][cargo/8066]
+
Misc
----
- [Rustdoc now supports strikethrough text in Markdown.][71928] E.g.
- [Rustdoc's CLI's extra error exit codes have been removed.][71900] These were
previously undocumented and not intended for public use. Rustdoc still provides
a non-zero exit code on errors.
+- [Rustc's `lto` flag is incompatible with the new `embed-bitcode=no`.][71848]
+ This may cause issues if LTO is enabled through `RUSTFLAGS` or `cargo rustc`
+ flags while cargo is adding `embed-bitcode` itself. The recommended way to
+ control LTO is with Cargo profiles, either in `Cargo.toml` or `.cargo/config`,
+ or by setting `CARGO_PROFILE_<name>_LTO` in the environment.
