# Changelog v0.3.18 - 2026-03-18

### Added
- **Missing tool bootstrap flow**: FCM now detects when a target CLI is absent, offers a minimal in-TUI install confirmation, runs the official global install command, then resumes the selected model launch automatically.

### Changed
- **TUI readability overhaul across every screen**: the main table, Settings, Help, Smart Recommend, Feedback, and Changelog overlays now share a semantic high-contrast theme system instead of a patchwork of hardcoded colors.
- **Global theme switching now works for real**: press `G` to cycle `auto → dark → light` live, and the Settings screen now exposes a visible `Global Theme` row for the same control.
- **Launcher binary resolution**: direct tool launches now search PATH plus common user bin directories so a freshly installed CLI can be reused immediately in the same FCM session.

### Fixed
- **Theme repaint bugs**: provider colors, tier colors, separators, badges, cursor highlights, and overlay backgrounds now update immediately when the theme changes instead of keeping stale import-time colors.
