v0.3.0

API Switch v0.3.0

Personal Model Cooldown Mechanism

Replaced the complex NEW-API style status code/keyword routing strategy with a simpler "model cooldown" mechanism designed for personal use: if it's not working, cool it down and try the next one.

Core Changes

• Model Cooldown: Any upstream failure triggers a 300-second cooldown. Cooled models are skipped in routing, and the request fails over to the next available model.
• Auto-Recovery on Success: A successful request automatically clears the cooldown state.
• User Controls Are Sacred: The enabled toggle is only controlled by the user. The system never automatically disables an entry �� it only sets cooldown timers.
• Simplified Strategy: Removed auto-disable status codes, auto-retry status codes, auto-disable keywords, and the 504/524 no-retry hardcode.

New Features

• API pool status indicators: ?? Normal / ?? Cooling down / ? Disabled
• "Usage Guide" sidebar menu linking to GitHub documentation
• Toast notifications replacing alert() dialogs

Improvements

• Test chat now sends requests directly to the upstream via Tauri command, bypassing the proxy port �� no fallback, no interference
• Log page: click any row to expand details, removed chevron icons
• Tray menu auto-refresh on cooldown/recovery/reorder/toggle
• Database startup compatibility check: auto-add new columns, missing config keys, and migrate old defaults

Upgrade Notes

• Fully backward compatible �� existing databases are automatically migrated on startup
• Default cooldown parameters: 1 failure �� 300s cooldown (old default of 4 failures/60s is auto-migrated)
• Settings page circuit breaker card now only shows "Failure Threshold" and "Recovery Wait Time"
