# Changelog v0.1.20 - 2026-02-22

### Added
- **Dynamic tier filtering**: Use E/D keys to filter models by tier during runtime
- Tier filter badge shown in header (e.g., `[Tier S]`)
- E key elevates filter (show fewer, higher-tier models)
- D key descends filter (show more, lower-tier models)
- Preserves ping history when changing filters

### Fixed
- **Error 401 with --tier flag**: Fixed issue where using `--tier` alone would show selection menu instead of proceeding directly to TUI
- Improved flag combination handling for better user experience
