RELEASE.md does not mention the change to allow adding docs to reexported items

At some point between Rust 1.34.0 and 1.39.0, the ability to add documentation to reexported items was added, but I can't find it mentioned in either the RELEASE notes or the rust-lang.org blog posts.

Maybe this should be mentioned in the RELEASE notes for the version that added that feature?

I have a foo crate that I use to test stuff, and used cargo +1.39.0 doc to document this:

/// Ooooh, ghost!
pub use std::marker::PhantomData;

This was changed in 1.38 (coincidentally also the release rust-std spiked from a 61.2 MB to 173.3 MB download).

@rodrimati1992 are you interested in making a PR?

[rodrimati1992]

@jyn514 Sure, what are the PRs that made this possible?

[jyn514]

Oh I have no idea 😆 I found it by bisecting.

Looks like #63048 is it
