Per-Package-Target Feature Unification Proposal

A new proposal for per-package-target feature unification aims to improve the Rust development experience, particularly for embedded workspaces. This change would allow developers to specify features at the package level, tailored to specific targets, enhancing flexibility and organization. If implemented, this could streamline configurations and reduce complexity in multi-target projects, making Rust more efficient for embedded systems and cross-platform applications.

PQ-RASCV: Post-Quantum Security for Embedded Rust

The PQ-RASCV-core project introduces post-quantum (ML-DSA-65) remote attestation with built-in SLSA provenance for no_std embedded Rust environments. This initiative addresses the 'harvest now, decrypt later' threat by incorporating quantum-resistant algorithms, crucial for long-term security in embedded systems. By integrating with the Embassy framework, this project enhances Rust's capabilities in building secure, future-proof embedded applications.
