Background Subagents by Default

Quieter Transcripts by Default

The TUI now summarizes each run of tool calls and thoughts into one collapsible activity row, so the answer is easier to follow. To see every step again, set Verbosity to medium or high in settings, or set session.verbosity in your TUI config; an existing setting is kept.#63207

Jump to an Earlier Prompt

In the desktop app, open Jump to message from the command palette or press Cmd+Alt+G (Ctrl+Alt+G on Windows and Linux) to search prompts across the current session and jump directly to one.#63585

Improvements

• CoreAdded experimental support for MCP events, behind the mcp_events flag.#63254#63261#63269
• CoreShell commands now survive server handoffs and keep their output when interrupted.
• CoreAdded experimental support for moving a shell command to the background when its timeout expires, behind the shell_timeout_background flag. With the flag on, an explicit timeout on a background command stops it.#63024#63703
• CoreLocal Windows shell commands now run through the process daemon.
• CoreAdded support for freeform tool input on compatible models.
• CoreAdded LM Studio decision-model support.
• CoreAgents are now told when their session is a fork. Thanks @hasta84.#63235
• CoreTool output truncation now keeps the beginning of the output and preserves a usable preview if the full output cannot be saved.
• CoreTail reads no longer load the entire file into memory.
• CoreProviders can present a client certificate for gateways that require mutual TLS. Set settings.tls with cert, key and an optional passphrase on the provider; values accept {file:} and {env:} like apiKey.#61832
• CoreWhen a subagent goes idle while its own background work is still running, its report to the parent now says it is still running, so the parent waits for the final report instead of treating the partial answer as done.#63675
• CoreCode Mode gets simpler structured results from file and skill tools: write and edit return their confirmation as a string, patch returns an empty result, and skill returns the skill's directory and content.#63616#63635#63618#63623
• TerminalSession IDs found in messages can now be opened directly.
• TerminalActivity tabs are clickable and open the correct view.
• TerminalShell mode has its own prompt color under the new designs.
• DesktopAdded the experimental Recent sessions sidebar, with cross-server recency, local pins, reordering, and standard session-row actions.
• DesktopRecent sessions are limited to the last seven days and 30 rows, and can be hidden or muted.
• DesktopAdded an experimental customizable sessions sidebar.
• DesktopMermaid diagrams can now be maximized for zooming and panning.#59250
• DesktopAdded Alt+Enter to place a follow-up first in the queue and Mod+Enter to steer the next queued prompt.
• DesktopHolding the modifier key now shows tab shortcut numbers.
• DesktopEach server’s terminal shell can be selected from its menu.
• DesktopAdded a free-limit panel in place of the composer when applicable.
• DesktopSession IDs are easier to find and copy.
• SDKEvent subscriptions can now receive experimental.mcp.event events from MCP event subscriptions.
• SDKModel capability schemas now advertise supported freeform tool-input formats.
• SDKSession throughput is now measured from the first streamed token.
• SDKSession creation documentation now clarifies the parentID field.
• ExtensionsPromise-based tools can cooperatively stop through ToolContext.signal.
• ExtensionsAdded the experimental session.fork hook.
• ExtensionsPromise plugin cleanup failures no longer prevent subsequent plugin replacements.
• Extensions@opencode/plugin/effect now exports Tool, so an execute.before hook can reject a call with Tool.Error without importing @opencode/schema/tool.#63698

Fixes

• CoreFixed case-only file renames in patches on case-insensitive filesystems.
• CoreFixed stale thinking being retained after Claude Agent prompts or tools change.

• CoreFixed saved API keys being omitted from local-model discovery.
• CoreLocal model discovery (Ollama, LM Studio, vLLM) waits up to 15 seconds per request instead of 1, so remote or tunnelled endpoints list their models, and a slow endpoint no longer delays other endpoints or config reloads.#63700
• CoreIn Code Mode, calling a namespace as if it were a tool now suggests up to three real tools under it.#63697
• CoreFixed retryable provider streams losing completed work when interrupted.
• CoreFixed GitHub Copilot requests using the wrong endpoint before models finish loading.
• CoreFixed exhausted request rate limits being treated as terminal. Thanks @Kyle-j-bush.#59816
