On June 26, 2025, the programming world got a little brighter with the release of Rust 1.88.0! Rust has long won over developers with its blend of high performance and memory safety, all without relying on a garbage collector. As someone who’s been following Rust since its early days, I can say each release feels like a mini celebration. This time, 443 developers from around the globe poured their hearts into making Rust even better.
For context: Rust 1.80 came out in July 2024, Rust 1.85.0 (aka Rust 2024) dropped in February 2025, and in May 2025, we celebrated 10 years since Rust 1.0 alongside the 1.87.0 release. Now, Rust 1.88.0 is here, and it’s packed with exciting updates.
Rust 1.88.0 isn’t just a patch - it’s a collection of changes that genuinely make developers’ lives easier. Here’s the rundown of the biggest highlights.
Say hello to naked functions! These are functions where the compiler skips generating the usual prologue and epilogue, letting you take full control of the assembly code with the #[unsafe(naked)] attribute and the naked_asm! block. If you’re writing drivers or working on embedded systems, this is a game-changer. It’s like being handed the keys to the low-level kingdom.
If you’re like me and love clean, readable code, you’ll adore this new feature in the Rust 2024 edition. You can now chain let bindings in if and while statements using &&. For example:
if let Some(x) = option && x > 0 { ... }
This makes complex conditions more compact and clear. Note that it’s only available in Rust 2024, so it’s time to upgrade!
The Cargo package manager just got smarter. It now automatically cleans up its cache, deleting network-downloaded files after 3 months and local files after 1 month of inactivity. If you’re notorious for neglecting cache cleanup (like me), this is a lifesaver. Just a heads-up: it won’t run in --offline or --frozen modes to avoid deleting anything critical.
Here’s a small but sweet addition: cfg! and #[cfg] now support true and false literals. This makes conditional compilation more intuitive, especially for platform-specific code. It’s the kind of quality-of-life improvement that makes you smile.
Rust 1.88.0 stabilizes a bunch of APIs, including handy methods like Cell::update and HashMap::extract_if. Plus, raw pointers now implement the Default trait, eliminating some minor annoyances. These tweaks make working with the standard library smoother and more powerful.
The i686-pc-windows-gnu platform has been demoted to Tier-2, meaning support is no longer guaranteed. If you’re still using it, consider switching to i686-pc-windows-msvc with SSE2 support for better reliability.
Every change in Rust 1.88.0 solves real-world problems. Naked functions are a boon for low-level coders. Let chains make your conditionals cleaner and faster to write. Cargo’s cache cleanup saves disk space, and stabilized APIs make the standard library even more robust. Even the i686-pc-windows-gnu downgrade is a nudge to keep your project future-proof.
Rust has always excelled at being both safe and fast, and updates like these make it more user-friendly too. Whether you’re building high-performance systems or just want bug-free code, Rust 1.88.0 has something for you.
Rust isn’t just a language - it’s a community. The fact that 443 people contributed to this release shows how vibrant and dedicated this group is. Cargo and crates.io are the backbone of Rust’s ecosystem, making dependency management and library sharing a breeze. The crates.io repository keeps growing, and Cargo keeps it all running smoothly.
In May 2025, we celebrated 10 years since Rust 1.0 - a milestone that reminded us how far the language has come. From a niche project to a tool used by giants like Mozilla and Microsoft, Rust’s success is all thanks to its open-source community.
Rust 1.88.0 is another step toward making programming safer, faster, and more enjoyable. With new features like naked functions and let chains, improvements to Cargo, and a thriving community, this release is a big deal. If you haven’t tried Rust yet or are still on an older version, now’s the perfect time to check out the official Rust blog or the GitHub release notes for all the details.
