==========================

Language

• Stabilize #![feature(let_chains)] in the 2024 edition.
  This feature allows &&-chaining let statements inside if and while, allowing intermixture with boolean expressions. The patterns inside the let sub-expressions can be irrefutable or refutable.
• Stabilize #![feature(naked_functions)].
  Naked functions allow writing functions with no compiler-generated epilogue and prologue, allowing full control over the generated assembly for a particular function.
• Stabilize #![feature(cfg_boolean_literals)].
  This allows using boolean literals as cfg predicates, e.g. #[cfg(true)] and #[cfg(false)].
• Fully de-stabilize the #[bench] attribute. Usage of #[bench] without #![feature(custom_test_frameworks)] already triggered a deny-by-default future-incompatibility lint since Rust 1.77, but will now become a hard error.
• Add warn-by-default dangerous_implicit_autorefs lint against implicit autoref of raw pointer dereference.
  The lint will be bumped to deny-by-default in the next version of Rust.
• Add invalid_null_arguments lint to prevent invalid usage of null pointers.
  This lint is uplifted from clippy::invalid_null_ptr_usage.
• Change trait impl candidate preference for builtin impls and trivial where-clauses.
• Check types of generic const parameter defaults

Compiler

• Stabilize -Cdwarf-version for selecting the version of DWARF debug information to generate.

Platform Support

• Demote i686-pc-windows-gnu to Tier 2.

Refer to Rust's platform support page
for more information on Rust's tiered platform support.

Libraries

• Remove backticks from #[should_panic] test failure message.
• Guarantee that [T; N]::from_fn is generated in order of increasing indices., for those passing it a stateful closure.
• The libtest flag --nocapture is deprecated in favor of the more consistent --no-capture flag.
• Guarantee that {float}::NAN is a quiet NaN.

Stabilized APIs

• Cell::update
• impl Default for *const T
• impl Default for *mut T
• HashMap::extract_if
• HashSet::extract_if
• hint::select_unpredictable
• proc_macro::Span::line
• proc_macro::Span::column
• proc_macro::Span::start
• proc_macro::Span::end
• proc_macro::Span::file
• proc_macro::Span::local_file
• <[T]>::as_chunks
• <[T]>::as_chunks_mut
• <[T]>::as_chunks_unchecked
• <[T]>::as_chunks_unchecked_mut
• <[T]>::as_rchunks
• <[T]>::as_rchunks_mut
• mod ffi::c_str

These previously stable APIs are now stable in const contexts:

• NonNull<T>::replace
• <*mut T>::replace
• std::ptr::swap_nonoverlapping
• Cell::replace
• Cell::get
• Cell::get_mut
• Cell::from_mut
• Cell::as_slice_of_cells

Cargo

• Stabilize automatic garbage collection.
• use zlib-rs for gzip compression in rust code

Rustdoc

• Doctests can be ignored based on target names using ignore-* attributes.
• Stabilize the --test-runtool and --test-runtool-arg CLI options to specify a program (like qemu) and its arguments to run a doctest.

Compatibility Notes

• Finish changing the internal representation of pasted tokens. Certain invalid declarative macros that were previously accepted in obscure circumstances are now correctly rejected by the compiler. Use of a tt fragment specifier can often fix these macros.
• Fully de-stabilize the #[bench] attribute. Usage of #[bench] without #![feature(custom_test_frameworks)] already triggered a deny-by-default future-incompatibility lint since Rust 1.77, but will now become a hard error.
• Fix borrow checking some always-true patterns.
  The borrow checker was overly permissive in some cases, allowing programs that shouldn't have compiled.
• Update the minimum external LLVM to 19.
• Make it a hard error to use a vector type with a non-Rust ABI without enabling the required target feature.
