This issue tracks the release notes text for #146882.

cc @cyrgani, @BurntSushi -- original issue/PR authors and assignees for drafting text

See the forge.rust-lang.org chapter about release notes for an overview of how the release team makes use of these tracking issues.

Release notes text

This section should be edited to specify the correct category(s) for the change, with succinct description(s) of what changed. Some things worth considering:

• Does this need an additional compat notes section?
• Was this a libs stabilization that should have additional headers to list new APIs under Stabilized APIs and Const Stabilized APIs?

# Compatibility Notes
- [Fully deprecate the legacy integral modules](https://github.com/rust-lang/rust/pull/146882). For example, `std::i32::MAX` should be accessed via `i32::MAX` instead.

[!TIP]
Use the previous releases for inspiration on how to write the release notes text and which categories to pick.

Release blog section

If this change is notable enough for inclusion in the blog post then this section should be edited to contain a draft for the blog post. Otherwise leave it empty.

[!NOTE]

If a blog post section is required the release-blog-post label should be added (@rustbot label +release-blog-post) to this issue as otherwise it may be missed by the release team.

Read the forge.rust-lang.org release-notes chapter and compare the proposed text with previous releases. Review change #146882, then update the Compatibility Notes category and wording as needed and decide whether a release blog section is required. The issue is done when the release notes text is finalized and any needed blog-post label or draft is present.
