cargo-semver-checks 0.47.0

v0.47.0

on Rust Cargo

In this release

• 7 new lints
• Spotlight: Google Summer of Code

This release also includes a workaround for a Rust 1.94 rustdoc bug that caused cargo-semver-checks to crash in certain projects. We contributed the fix to rustdoc and are including a workaround here so our users can continue using cargo-semver-checks with Rust 1.94.

This release requires Rust 1.91+ both to install (MSRV) and at runtime.

Spotlight: Participating in Google Summer of Code

cargo-semver-checks is once again participating in Google Summer of Code, as part of the Rust project!

This is the third year in a row that students from all over the world are eligible to submit proposals for multi-month projects aimed at improving Rust and its tooling such as cargo-semver-checks. An initial list of suggested proposal topics is available here, and student are of course welcome to bring their own ideas as well.

The application period runs from March 16-31, 2026. Good luck to all applicants — we're excited to see you and we can't wait to see what you build!
