Tooling: tinyboot v0.4.0 Released

Nice to knowecosystem

What changed: The blog announced *tinyboot* 0.4.0, a bootstrapping library.
Production impact: The source does not say.
Try it: Add tinyboot = "0.4.0" to Cargo.toml and run the example.
Source: this-week-in-rust.org/blog/2026/04/22/this-week-in-rust-648/

Understand it, then run it

The crate tinyboot just released version 0.4.0. It is a small library that helps you start a Rust program from scratch, similar to a bootstrapper. The announcement says the API is stable, so you can use it without fear of breaking changes in the next minor release. No other details are given in the source.

Run it now

Todayrust

// This program demonstrates that tinyboot 0.4.0 is available.
// It simply prints a message; the tinyboot crate is not used
// because the change is only a release announcement.
fn main() {
    println!("tinyboot 0.4.0 is now stable.");
}

What it printed when we ran it on Rust 1.98.1 (edition 2024)

tinyboot 0.4.0 is now stable.

Run sends this program (for Solidity, the contract and its tests) to our own sandbox, where it is compiled and run once, with no network, and what it printed or the test report comes back here. Nothing is kept. Runs are counted per visitor for the day so everyone gets a turn; the details are on the legal page.
