What's New

Configurable Agent Settings #2495

Agent behavior is now configurable from the desktop settings UI. You can override built-in presets, preview prompt templates, and reuse the same agent definitions everywhere you launch work without editing config files by hand.

• Adjust model, labels, descriptions, commands, and prompt templates from one settings page
• Changes save immediately and can be reset back to defaults
• The same shared agent presets now power workspace creation and task launch flows

Streamlined Workspace Modal #2391 #2506 #2500 #2513

The workspace modal now keeps project selection, prompts, images, PRs, and issues in one flow, so it is faster to launch a workspace with complete context.

New workspace modal

• Prompt-first creation flow with project selection built directly into the modal
• Project avatars, GitHub owner details, and inline Add from GitHub in the selector
• Prompt text, image attachments, linked PRs, linked issues, and selected agent all live in the same streamlined flow
• Prompt text, attachments, and selected agent persist when you close and reopen the modal
• Branch prefix previews, better long-name truncation, and PR lookup by pasted GitHub URL

Tab and Pane Enhancements #2488 #2487

Desktop layouts are more flexible now. You can merge an entire tab into another pane layout with drag-and-drop, and rename pane headers inline to keep dense workspaces organized.

Drag tab into pane

• Drag a top-level tab onto another tab's split zones to merge it left, right, top, or bottom
• Source tabs are removed cleanly after the merge, preserving pane ownership and layout state
• Double-click pane headers to rename them directly in place

Improvements

• V2 workspace sidebar - Workspaces are grouped by project in the redesigned sidebar, with the newer project-first flow feeding directly into that structure #2399
• Linked Linear issue pills - Linear issues referenced in agent tasks now render as inline pills with the issue title and status, so you can reference tasks in chat without leaving context #2383

Improved Chat View — Now Generally Available #1876 #1973 #1983

The redesigned chat interface is now generally available to all users. Previously behind early access, the new chat view features refreshed tool call visuals with collapsible panels, improved diff rendering, and cleaner file views. Superset's own MCP tools—tasks, workspaces, and agent sessions—now render as rich, interactive cards directly in the chat. Superset Chat is also available as a first-class agent option with its own launch config and icon.

Open Worktree with Prompt #1882 #1912

The new workspace modal has been redesigned with a send-to-agent flow. When creating a worktree you can now write a prompt that gets sent directly to an agent in the new workspace—describe what you want built and the agent starts working as soon as the workspace is ready. The modal also includes a project selector, an import flow for cloning repos, and auto-generated branch names derived from your prompt.

Open worktree with prompt

• Write a task prompt when creating a new workspace

Custom worktree location settings

New Project Page #1623

Project creation now has a dedicated full-page experience instead of a dialog. Navigate to it from the welcome screen or sidebar footer and choose between two options available now: create an empty Git repo or clone from a URL. A template starter tab is visible and marked "coming soon." A directory picker defaults to ~/.superset/projects with a native browse button.

Chat UI Overhaul (Early access only) #1693 #1697

The chat interface got a significant visual refresh. Streaming messages now animate with a progressive typing effect, tool output panels are collapsible to reduce noise, and loading/thinking states use a unified compact shimmer.

Chat - Still in preview #1413

Chat got a major upgrade this week. Streaming responses now support interactive tool-approval flows, so you can review and approve each tool call as it happens. A new multi-provider model picker lets you choose between providers and models. Agent and tool calls render as expandable UI blocks with tool-specific displays, and a new web search tool lets Claude fetch and reference live content.

We also shipped a series of fixes to MCP connectivity — replacing the stagnant mcp-handler library with a direct SDK transport #1518, fixing OAuth connections through the reverse proxy #1512, and resolving SDK version conflicts that caused session failures #1515 #1516.

Chat with tool approval

New Diff View, Powered by diffs.com #1308

The Changes view has been completely rebuilt with Pierre Computer's diffs.com engine — delivering a drastically improved diff experience in both UI and performance. Large changesets that previously lagged now render instantly, and the new interface makes reviewing diffs feel native and fluid.

The new viewer includes an edit mode toggle — switch between read-only review and live editing, and hit Ctrl+S to save changes directly from the diff.

• Workspace-scoped base branch — base branch selection is now per-workspace instead of global, so diffs always compare against the right branch #1329
• Preserved file explorer state — expanded folders, scroll position, and selection persist when switching between Changes and Files tabs #1297
• Compact tab buttons — Changes and Files tabs collapse to icon-only mode with tooltips when the sidebar is narrow #1334

Powerful Preset Settings #1320

Terminal presets now have granular auto-apply controls. Configure when presets run independently for workspace creation and new tabs — so you can auto-run setup commands on new workspaces without them firing every time you open a tab.

• Apply preset on workspace creation — controls initialization commands when spinning up workspaces
• Apply preset on new tab — controls whether presets run when opening new tabs, panes, or splits
• Explicit preset launches via hotkey or menu always work regardless of these settings

Improvements
