Bug fixes and performance improvements 1. Added support for DeepSeek V4 Pro thinking blocks 2. Added support for transferring search actions to the Google Search Engine (API key required) 3. Fixed the advice issue in the latest Claude Code version 4. Fixed minor tool-calling issues with the DeepSeek V4 Pro model

• Web search now supports multiple providers — switch directly from the menu bar • Improved Claude Code compatibility with layered thinking block handling • New cost tracking shows real-time savings across providers

bug fixes.

Branch Coordination & Response Replay When multiple requests target the same conversation branch, ModelProxy now coordinates them: the first request proceeds normally while subsequent requests wait and receive a cached replay, avoiding redundant upstream calls. Session Lineage Persistence Conversation branch history now persists to disk. Branch transcripts survive app restarts, so context about which model handled which turn is retained across sessions. Streaming Reliability - SSE normalizer resets all state on finish, making repeated use safe - Malformed JSON events in SSE streams pass through instead of dropping - Copy-on-write protection prevents data loss if persistence fails mid-write New Configuration Options - Signing domain editor per vendor - Replay policy editor for fine-tuning branch replay behavior Under the Hood - Replay capture extracted into dedicated BranchReplayRecorder with 1MB size limit - Lineage data stored as JSON in Application Support directory - Narrowed internal types for better type safety - Swift 6 concurrency improvements
