# Changelog v0.3.9 - 2026-03-16

### Improved
- **Enhanced `--premium` flag**: Now applies strict elite-only constraints. Shows only **S/S+** tier models with perfect health (**UP**) and a good verdict (**Perfect**, **Normal**, or **Slow**). Models with 429 errors, auth failures, or poor performance are automatically hidden.
- **Accurate Token Usage Tracking**: The "Used" column now uses the persistent `token-stats.json` file as the source of truth, providing accurate historical totals instead of only the most recent logs.
- **Enhanced Log Transparency**: The request log page now always shows the requested model and the actual upstream model (e.g., `llama-3.1-405b → meta/llama-3.1-405b-instruct`) whenever they differ.
- **Pretty Provider Labels**: The request log page now uses human-readable provider labels (e.g., "NVIDIA NIM", "SambaNova") instead of raw internal keys.
- **Fixed Tier Filtering Family Logic**: Updated `--tier S` behavior to correctly include both **S** and **S+** models (matching documentation).
