  • CLI
  • MCP

The prerelease comparison improves feedback at security boundaries: completed hooks can leave visible warnings, approval rejections retain their reasons, and Windows exec-server work gains sandboxing.

Alpha release context: 3 official tags were published that UTC day (rust-v0.145.0-alpha.27, rust-v0.145.0-alpha.28, rust-v0.145.0-alpha.29). The full comparison contains 41 commits and at least 300 changed files.
