Under Compatibility Notes, the release notes mention: > Unfortunately the [`x86_64-unknown-uefi` platform can not be built](https://github.com/rust-lang/rust/issues/62785/) with rustc 1.39.0. Should that be 1.38.0? ---

The link for **Stabilized APIs** `any::type_name` is incorrect. ---

`std::any::type_name` was created and stabilized within the same version, so the link won't work until 1.38.0 goes live. You can see that redirecting to the beta docs the equivalent link works: [https://doc.rust-lang.org/beta/std/any/fn.type\_name.html](https://doc.rust-lang.org/beta/std/any/fn.type_name.html). ---

Uh, yeah, got busy with other stuff today and I forgot 😅. [Posted it](https://www.reddit.com/r/rust/comments/d8pn0t/rust_1380_prerelease_testing/). Also [opened a PR to fix the wrong rustc version](https://github.com/rust-lang/rust/pull/64742) in the compatibility section. ---

I would like signal to downstream that with this version, cargo uses libgit2-sys crate which broke the compatibility with libgit2-0.28 branch and depend on unreleased libgit2 version. - [rust-lang/git2-rs/issues/458](https://github.com/rust-lang/git2-rs/issues/458) - [rust-lang/rust/issues/63476](https://github.com/rust-lang/rust/issues/63476) Running cargo break at runtime with such error: ```rust $ cargo install test Updating crates.io index error: failed to fetch `https://github.com/rust-lang/crates.io-index` Caused by: invalid version 3 on git_proxy_options; class=Invalid (3) ``` FreeBSD already have a local patch to restore the compatibility at [lang/rust-nightly/files/patch-vendor\_libgit2-sys\_lib.rs](https://svnweb.freebsd.org/ports/head/lang/rust-nightly/files/patch-vendor_libgit2-sys_lib.rs) , and I intent to use it too for OpenBSD too. ---
