v0.9.0-beta.2 - Hardened Signature API

Breaking Changes

This release includes a significant security improvement to the signature API that prevents accidental corruption of secret key material.

What changed

• Removed AsMut<[u8]> implementations from all signature secret key types
• Secret keys can no longer be directly mutated through byte access
• New trait-based API for safe key operations

Migration Guide

If your code was using AsMut<[u8]> or AsRef<[u8]> on secret keys:

• Use key.seed() to access key seed material
• Use key.serialize() methods for import/export operations
• See the updated documentation for each algorithm
