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

Early Preview of Chat GUI #1309

A native AI chat interface built right into Superset — and it works with your existing Claude Code sessions. Pick up where you left off without switching windows.

Existing session support — scan and restore previous Claude Code sessions so you never lose context
Slash commands — type / to browse available commands with fuzzy search and keyboard navigation
File mentions — tag files with @ and fuzzy search to pull in exactly the context you need #1307
Rich tool rendering — tool calls display with specialized UI for bash output, web searches, file diffs, and user questions
Session persistence — chat sessions survive app restarts with local storage and automatic restore #1287

This is an early preview — general availability is coming next week. We'd love your feedback in the meantime.

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
