v1.74.0

Libraries

• Implement From<OwnedFd/Handle> for ChildStdin/out/err

• impl Step for IP addresses
• Implement From<[T; N]> for Rc<[T]> and Arc<[T]>

Stabilized APIs

These APIs are now stable in const contexts:

• core::mem::transmute_copy
• str::is_ascii
• [u8]::is_ascii

Cargo

• In Cargo.toml, stabilize [lints]
• Stabilize credential-process and registry-auth
• Stabilize --keep-going build flag
• Add styling to --help output
• For cargo clean, add --dry-run flag and summary line at the end
• For cargo update, make --package more convenient by being positional
• For cargo update, clarify meaning of --aggressive as --recursive
• Add '-n' as an alias for --dry-run
• Allow version-prefixes in pkgid's (e.g. --package flags) to resolve ambiguities
• In .cargo/config.toml, merge lists in precedence order
• Add support for target.'cfg(..)'.linker

Rustdoc

• Add warning block support in rustdoc
• rustdoc-search: add support for type parameters
• rustdoc: show inner enum and struct in type definition for concrete type

Compatibility Notes

• Raise minimum supported Apple OS versions
• make Cell::swap panic if the Cells partially overlap
• Reject invalid crate names in --extern
• Don't resolve generic impls that may be shadowed by dyn built-in impls
• The new impl From<{&,&mut} [T; N]> for Vec<T> is known to cause some inference failures with overly-generic code. In those examples using the tui crate, the combination of AsRef<_> and Into<Vec> leaves the middle type ambiguous, and the new impl adds another possibility, so it now requires an explicit type annotation.

I believe it is definitely not intended, but bump check didn't catch that other public member crates has got an update of their rust-version from workspace inheritance. Personally I like it not bumping, as there is no actual change needed to publish. Just wonder what's our policy in this case?

[epage]

I'm fine with that and actually wonder if we should switch the workspace to MSRV:3 so the public crates aren't forced to be released every time.

If we could diff the packages and ignore certain types of changes, that'd be even better :)

This sounds good and simpler to me 👍🏾
