[0.9.90] - 2026-05-08

Added

• Added reasoning mode support for Anthropic/OpenAI with thinking/reasoning parameter passthrough, cache control, and prompt caching markers.
• Added browser plugin capability with IPC for cookie cleanup and tool re-registration on project switch.
• Added new DAO interfaces for querying user messages only and for reverse-lookup run changes by sessionId and toolUseIds.
• Added reasoning effort mapping directly supporting xhigh without client-side normalization.

Changed

• Refactored streaming chat and tool chain to be runtime-state-driven: removed legacy long_running_mode field, now driven by current runtime state and configuration.
• Narrowed theme presets to the default only; removed global theme panel, SSH terminal theme panel, and redundant session title display. Settings migration falls back to default theme on old versions.
• Simplified message list to always load all session messages at once; removed "load earlier messages" button, auto-fill, and scroll anchor recovery. Added session-level deduplication to prevent duplicate tail tool restores.
• Completed Anthropic SSE/usage handling: unified message_start/message_delta/message_stop and data.type, aggregated input/output/cache read/cache creation/reasoning token stats, with cache writes billed per 5m/1h buckets. Tool call end events flush at stream end; message_end acts as fallback.
• Rewrote Clarify mode prompt as a strict "clarify first, then plan" flow with enforced AskUserQuestion/EnterPlanMode/ExitPlanMode closure.
• Enhanced file edit tool to preserve original line-ending style (CRLF/LF), avoiding mixed line endings.
• Tool output with structured errors is now recognized as failure instead of success.
• Run change queries expanded from exact runId match to also support sessionId and toolUseIds reverse-lookup.
• Improved stream rendering with new typing render pool, finer-grained animation classes, and progressive Markdown/table/component reveal.
• AssistantMessage now binds run changes precisely via tool_use ids, filtering out failed file tool results.
• Cron recovery marks still-running background runs as aborted on app restart to prevent hanging states.
• Enhanced request header forwarding security to avoid duplicating body-managed headers.

Fixed

• Fixed multi-line code block and local path recognition in Markdown rendering.
• Stopped duplicate tail tool restoration when resuming sessions.
