Published: 2026-07-05 Tags: release feature enhancement fix

NextClaw v0.22.0 is an NPM stable minor release. This note separates what is new, what improved, what was fixed, and what changed in defaults or compatibility.

Features

• You can queue another message while an agent run is active; queued drafts are sent in order after the current run completes.
• show_file, show_url, and show_panel_app now provide clearer display entry points.
• Local HTML can open as a rendered preview in the right workspace panel, with scripts and relative assets behaving closer to a normal browser.
• The new view_image agent tool lets models read local PNG, JPEG, WebP, and GIF files.

Enhancements

• Long conversations now have a floating action to return to the latest message, and completed reasoning or tool-process content collapses behind a summary.
• show_url opens in browser-like tabs with address, refresh, and external-open controls; source and rendered previews for the same file can stay open separately.
• File previews now support syntax highlighting, and breadcrumbs can browse nearby folders directly.
• Night theme is now available, with readability improvements for Markdown, status surfaces, error notices, switches, attachment tokens, marketplace details, and session metadata.
• SideDock, DocBrowser, auto-collapsing sidebar behavior, compact tabs, and Slash panel interactions are more stable and consistent.

Fixes

• Uploaded files, uploaded images, and pasted images are no longer dropped when sending a message.
• Image attachments no longer send a default detail: "auto" value that some OpenAI-compatible providers reject.
• Failed session previews now appear in the chat detail view, not only in the session list.
• Abort signals during tool calls now propagate to NCP/MCP tool execution.
• Session activity previews no longer show false failure states as easily.

Defaults and Compatibility

• The learning loop is disabled by default for new configs. Existing explicit user settings are preserved.
• NCP events now include standard timing and message lifecycle fields, making process duration and completion state easier to track.
• This is an NPM stable minor release available through the normal NextClaw NPM install or update flow.
