Bug Fixes

  • Fix requests remaining stuck beyond the idle timeout when a model response stream stops producing output and its transport ignores cancellation. by @tianyicui
  • Fix entire DeepSeek requests being blocked when plugin package metadata cannot be read or auxiliary request-extension preparation fails. by @turtle1999, @turtle2099
  • Fix uncaught errors after credential, configuration, and skill watchers close, and premature resource release during Agent shutdown. by @tianyicui, @kermanx
  • Fix editing or deleting model settings from stale data during refresh, including newly saved selections missing from the editor. by @tianyicui
  • Fix persistent PowerShell calls failing to settle promptly after large amounts of output scroll in some Windows environments. by @Chinesezjc
  • Fix the Claude Code Mods Blast Radius example executing tools after cancellation on Windows when the sleep command is unavailable. by @tianyicui
  • Fix Trajectory marking waiting, streaming, or retrying requests as completed and showing results before compaction tasks finish. by @turtle2099, @kermanx
  • Fix background workflows being marked interrupted while still running after their parent tool step or conversation turn ends normally. by @turtle2099
  • Restore image paste and drop in continuable subagent composers, including images sent while running and follow-ups after completion. by @ZiyaZhang

  • Fix corrupt small Finder icons for the macOS app and icons shown in application copy and replacement dialogs. by @07akioni
  • Fix PTY worker processes remaining after a terminal exits in Windows Desktop. by @winewill
  • Improvements

    • Add General settings for independently choosing fonts and sizes for interface text, code and tool output, and sidebar terminals. by @turtle2099
    • Add microphone selection to voice input, with an input-device selector and live levels for the selected device in plugin details. by @yudshj
    • Allow Web to bind to a specific IPv4/IPv6 address and configure native HTTPS listeners through --tls-cert and --tls-key. by @oraluben
    • Support scrolling and copying full commands in Shell and plugin installation details, and expand background Bash inputs and launch receipts. by @tianyicui
    • Improve previews of files containing overlong source lines, rendering those lines without syntax colors while regular lines retain highlighting. by @turtle2099
    • Improve automatic session titles by retaining adequate titles for same-topic follow-ups, additional details, and requests to continue. by @tianyicui, @ZiyaZhang

    • Add migration guidance to sidebar forks and subagent catalog browsing, directing users to open the original session when migration is required. by @imccyu

    Chores

    • Apply Session filesystem sandbox policies to Python PTC; custom compositions require sandbox and sandboxPolicy services. by @tianyicui
    • Remove the both mixed tool-presentation mode, leaving native and ptc. Update configurations and API calls that use the removed mode. by @tianyicui
    • Remove the per-row dshHome setting from agent-instructions and resolve instruction directories from the process DSH_HOME or its default. by @tianyicui
    • Unify subagent execution and completion notifications, with tools returning child IDs immediately. Custom SDK runtimes must support session/wait. by @Dudu-0223
    • Deliver Agent Team messages directly to the target Inbox, removing the separate outbox, automatic retries, and resend deduplication. Migrate affected configuration and result fields. by @Dudu-0223
    • Change the default SDK profile from a fixed coding-agent persona to a general AI Agent identity for general-purpose tasks. by @Dudu-0223
    • Support optional plugins in Minimal mode and allow Claude Code and Codex bundles in headless, SDK, and ACP profiles. by @turtle2099
    • Update runtime utilities, MCP protocol integrations, image processing, and client-rendering dependencies with compatible security fixes. by @tianyicui
    • Update pi-ai to 1.0.2, including upstream model-catalog updates and adapter fixes. by @tianyicui
