+
+The [MCP to raise the three UEFI targets to tier 2](https://github.com/rust-lang/compiler-team/issues/555) by [@dvdhrm](https://github.com/dvdhrm) was recently approved. 
+Following that we merged a PR to [dist builds of the UEFI targets](https://github.com/rust-lang/rust/pull/103933) so that you can install them via rustup (e.g. `rustup target add --toolchain nightly x86_64-unknown-uefi`), and a PR to [add an initial QEMU test](
+https://github.com/rust-lang/rust/pull/101703) for the x86_64 UEFI target to help prevent regressions from landing.
+
+The initial nightlies containing the prebuilt UEFI targets revealed some issues in `compiler_builtins` which we fixed and are in the [0.1.84](https://github.com/rust-lang/compiler-builtins/compare/0.1.83...0.1.84) release.
+Finally, we [changed the C compiler for the UEFI targets from gcc to clang](https://github.com/rust-lang/rust/pull/104622), which resolved some linker problems. 
+As of the 2022-11-22 nightly, the three UEFI targets should be fully usable, which means you no longer need to use the unstable `-Zbuild-std` feature.
