Announcing rustup 1.29.3
TL;DR
Rustup 1.29.3 has been released, addressing minor regressions including an 'Illegal instruction' error on specific x86_64 CPUs lacking SSE4.1 support. This update enhances the reliability of Rust installations.
✦ Why It Matters
Update rustup today to avoid potential errors on older x86_64 CPUs.
Key Takeaways
- Update rustup to version 1.29.3 for improved stability.
- Close any running applications using rustup before updating.
- Check CPU compatibility with SSE4.1 to avoid errors.
- Stay informed about future rustup releases for optimal performance.
Full Summary
Rustup is the official tool for installing the Rust programming language, which is designed for building reliable and efficient software. The latest release, version 1.29.3, fixes several minor issues from the previous version, notably an 'Illegal instruction' error that affected certain x86_64 CPUs that do not support the SSE4.1 instruction set.
This error could hinder the functionality of Rustup on those systems, making the update crucial for users with older hardware. To upgrade, users simply need to close any applications using rustup and run the update command.
This patch ensures that developers can continue to use Rust without encountering these specific errors, thereby improving the overall user experience. Regular updates like this are essential for maintaining software reliability and performance.
