What's New
Newer release adds PowerShell security patches and installer collision handling
New Features
- GateGuard recognizes destructive PowerShell commands and prevents variable hiding.
- Installer rejects collisions with user-owned files.
- Hook entrypoints handle larger JSON payloads with bounded reads.
- Pi adapter selects the actual Node runtime instead of executing a compiled host.
Improvements
- Security hardening for PowerShell with dynamic command handling.
- Installer collision handling preserves ownership hashes of untouched files.
- Hook JSON parsing improvements for larger payloads.
Bug Fixes
- Guided setup revalidates preview to prevent false success.
- Uninstall rejects invalid dry-run values instead of silently allowing.
Upgrade Notes
Review GateGuard exemption globs to ensure relative paths are used. Verify hook entrypoint configurations for JSON payload limits.
