+- Updated the GitHub RSA SSH host key bundled within cargo.
+  The key was [rotated by
+  GitHub](https://github.blog/2023-03-23-we-updated-our-rsa-ssh-host-key/) on
+  2023-03-24 after the old one leaked.

+  [#11635](https://github.com/rust-lang/cargo/pull/11635)
+- Marked the old GitHub RSA host key as revoked. This will prevent Cargo from
