- Fix Invalid Date display in Dashboard notifications - Fix timezone offset (8 hours) in Trading Records time display - Fix position closing failures due to commission discrepancies (fetch actual exchange position size for reduce_only orders) - Fix IBKR connection error 'no current event loop in thread' by ensuring asyncio event loop exists - Fix duplicate orders on same candle by extending signal deduplication to close signals - Add responsive design for Profile page (mobile-friendly) - Remove unused strategy_code module and database table - Fix LLM service to support multiple providers (OpenRouter, OpenAI, DeepSeek, Grok, Google) - Add auto-detection of configured LLM provider based on API key availability - Fix AI code generation to use unified LLMService with proper provider selection - Fix crypto symbol format handling (ETH/USDT no longer becomes ETH/USDT/USDT) - Fix Commission display showing '0E-8' in Trading Records - Fix P&L display for signal-only trades (show '--' for unrealized P&L) - Fix OAuth login not updating last_login_at for new users - Add migration script for notification_settings column - Update env.example with new LLM provider configurations - Remove ESLint rule that was not defined in config
