FuXi 0.1.6 Release Announcement

Release Date: September 7, 2026

FuXi 0.1.6 is now available. This release focuses on core experience consistency and stability: unified session and message handling, hardened login flow, cross-platform compatibility improvements, and a number of stability fixes.

New Features

  • Unified session & message handling: chat messages are consolidated into a single message model, removing inconsistencies between multiple handling paths; message parent-child chains are preserved more completely, and partially-compacted history survives session resume.
  • Hardened login flow: cross-process token refresh is serialized to prevent token-chain failure; tokens are refreshed proactively before expiry to avoid forced re-login; login no longer times out — it waits until the user cancels.
  • Model selection validation: the /model command now validates that the selected model is supported by the current endpoint, giving clear feedback when an invalid model name is entered.

Improvements & Fixes

  • Engine: empty responses automatically retry via non-streaming requests; fixed repeated injection of external file changes and conditional memory; coordinator queue drained before every request; gateway length errors correctly recognized as context-window overflows.
  • Bash / Windows: unified command-line parsing reduces misclassification; strict UTF-8 subprocess output on Windows avoids garbled text; nested-heredoc crash fixed; startup git-bash check and working-directory exclusion added.
  • UI & Rendering: markdown rendering improvements, box-drawing table format, sidebar reasoning state and session cost, and chat lag fixed on huge content; CJK character-width handling now applies only to legacy Windows consoles.
  • Tasks / Agent: standardized task IDs and output paths; notification queue priorities (immediate / later / next); stricter stop-task conditions; agent_busy claim check.
  • Files & Search: more accurate search timeouts; staged protection for very large file reads; Grep content checks and UNC path handling fixed.
  • MCP: /mcp toggle persisted per-project; improved port allocation and lock-backoff; staged truncation for tool output.
  • Permission & Sandbox: static directory rules support subtree matching; sandbox configuration now takes effect with settings; unified session grant logic.
  • Context compaction: staged decision for file restore after compaction; improved shared-cache partial compaction.
  • Image recognition: recognition configuration is endpoint-scoped and no longer affects the main model's vision judgment; recognition-model refusals are never cached.
