Scrypto 1.3.1: Modern Rust Support

Overview

Scrypto 1.3.1 removes the Rust 1.81.0 version lock that previously constrained Radix developers. The update resolves conflicts between modern WASM compiler optimizations and Radix Engine safety requirements by rebuilding the Rust standard library during package compilation, explicitly using the MVP WASM feature set.

Developer Benefits

• Access to Rust 1.92.0+ features, Clippy improvements, and formatting enhancements
• Better IDE integration with modern Rust tooling
• Easier integration with third-party no_std crates requiring updated Rust versions
• Future-proof development environments

The Radix Engine Toolkit is slated for updates to support Scrypto 1.3.1 compatibility.
