Release v0.2.0

Summary

This release focuses on architectural maturity and stability. We have moved away from the monolithic structure of v0.1.3 to a modular design, cleaned up experimental code paths, and hardened the runtime against edge cases.

Architecture & Codebase Cleanup

• Modular Shell Architecture: Refactored the shell implementation from a monolithic shell.py into dedicated modules (runtime, ui, pty, interaction) for better separation of concerns.
• Test Reorganization: Aligned test structure with the new architecture, moving from top-level files to focused coverage under tests/shell.
• Pruning: Removed unfinished planning and research paths (src/aish/plans, legacy tools) that were present in v0.1.3 to reduce technical debt.

CLI & User Experience

• Model Management: Streamlined CLI entry points. aish models auth is now the primary entry, with aish models usage providing detailed context on auth states and providers.
• Prompt Customization: Extended configuration capabilities with prompt_theme, enabling reusable prompt styles beyond the scripting features in 0.1.3.
• Interaction Flow: Decoupled UI logic from runtime logic, allowing for more explicit handling of control events, editing states, and security confirmations.

Reliability & Security

• Signal Handling: Improved robustness for Ctrl+C, long-running PTY sessions, and shell recovery scenarios.
• Noise Reduction: Suppressed false error hints caused by SIGPIPE during pager exits.
• Security Fix: Patched a command injection vulnerability in the shell history path.
• CI/CD: Added opt-in live smoke tests and a dedicated workflow to verify real-provider integration and installed bundles.
