This should be good as far as capturing noteworthy items, but suggestions are welcome in case I missed anything, especially for interesting "internal changes". I still need to tweak a lot of the wording and link stabilized APIs too.

The stabilization of https://github.com/rust-lang/rust/pull/95860 has been reverted in https://github.com/rust-lang/rust/pull/99435. (hasn't been backported yet, though)

I think the likely highlights for a blog post would be:

  • I/O Safety, with a detailed explanation and some guidance about using it (e.g. using this instead of RawFd in libraries).
  • explicit_generic_args_with_impl_trait (as a paragraph-sized note with one code example)
  • The removal of migration mode in the borrow checker (as a brief mention with a link to the post at https://github.com/rust-lang/blog.rust-lang.org/pull/989 , which we should merge before the release).
