 This script is the definitive, all-in-one integration for Anthropic models in OpenWebUI. It
 combines the best features from multiple community scripts into a single, robust, and
 future-proof solution.
+Changelog v8.5:
+- Removed cost tracking functionality (ENABLE_COST_TRACKING valve, MODEL_PRICING, cost calculation methods)
+- Removed cost display from responses and event emissions
+- Simplified _get_cache_info to only show token counts and cache hit percentage
+- Removed conversation cost storage and tracking
+
+Changelog v8.3:
+- Added comprehensive event emitter integration for user visibility
+- Implemented _emit_status() and _emit_message() helper methods
+- Added status updates for non-streaming requests (connecting, success, failure)
+- Added progress indicators for streaming responses (thinking, tool use, completion)
+- Made cache info visible at end of streaming responses (previously only logged)
+- Added event emissions for all error conditions with proper status updates
+- Enhanced user experience with real-time UI feedback throughout request lifecycle
+
 Changelog v8.2:
 - Improved cache control to use default 5-minute ephemeral caching (per Anthropic spec)
 - Improved content block normalization with dedicated helper methods
