* Sat Jun 03 2023 William Brown Version 1.70.0 (2023-06-01) Language--------- [Relax ordering rules for `asm!` operands](https://github.com/rust-lang/rust/pull/105798/)- [Properly allow macro expanded `format_args` invocations to uses captures](https://github.com/rust-lang/rust/pull/106505/)- [Lint ambiguous glob re-exports](https://github.com/rust-lang/rust/pull/107880/)- [Perform const and unsafe checking for expressions in `let _ = expr` position.](https://github.com/rust-lang/rust/pull/102256/) Compiler--------- [Extend -Cdebuginfo with new options and named aliases](https://github.com/rust-lang/rust/pull/109808/) This provides a smaller version of debuginfo for cases that only need line number information (`-Cdebuginfo=line-tables-only`), which may eventually become the default for `-Cdebuginfo=1`.- [Make `unused_allocation` lint against `Box::new` too](https://github.com/rust-lang/rust/pull/104363/)- [Detect uninhabited types early in const eval](https://github.com/rust-lang/rust/pull/109435/)- [Switch to LLD as default linker for {arm,thumb}v4t-none-eabi](https://github.com/rust-lang/rust/pull/109721/)- [Add tier 3 target `loongarch64-unknown-linux-gnu`](https://github.com/rust-lang/rust/pull/96971)- [Add tier 3 target for `i586-pc-nto-qnx700` (QNX Neutrino RTOS, version 7.0)](https://github.com/rust-lang/rust/pull/109173/),- [Insert alignment checks for pointer dereferences as debug assertions](https://github.com/rust-lang/rust/pull/98112) This catches undefined behavior at runtime, and may cause existing code to fail. Refer to Rust\'s [platform support page][platform-support-doc] for more information on Rust\'s tiered platform support.
