# Changelog v0.1.21 - 2026-02-22

### Refactored
- **Simplified tier filtering architecture**: Replaced complex object recreation with simple `hidden` flag system
- **Flags as shortcuts**: `--tier S` now just sets initial state instead of blocking dynamic filtering
- **Dynamic filtering preserved**: E/D keys work seamlessly even when starting with `--tier` flag

### Fixed
- **Ping loop bug**: Fixed issue where filtered models weren't pinged due to using wrong results array
- **Initial ping bug**: Fixed issue where initial ping used wrong results array
