## Bug Fixes
- 💥 **Admin functions page crash fix.** The admin Functions tab no longer crashes when clicked, fixing a null reference error that occurred while the functions list was loading. #21661, Commit
- 💀 **Cyclic chat history deadlock fix.** Chat histories with circular parent-child message references no longer cause the backend to freeze when syncing usage stats. The system now detects and safely aborts when encountering cyclic message references. #21681
- 🔀 **Model fallback routing fix.** Custom model fallback now works correctly across all model types, preventing "Model not found" errors when the fallback model uses a different backend (pipe, Ollama, or OpenAI). #21736
- 🐛 **Default model selection fix.** Admin-configured default models are now properly respected when starting new chats instead of being overwritten by the first available model. #21736
- 👁️ **Scroll jumping fix.** Deleting a message pair after stopping generation no longer causes the chat to visually jump around, making message deletion smoother. #21743, Commit
- 💬 **New chat message handling fix.** Fixed a bug where clicking "New Chat" after sending a message would silently drop subsequent messages. The system now properly clears pending message queues when starting a new conversation. #21731
