Repository navigation
Modesto v0.4.0 — Berkeley
Berkeley is the redesign release. It packages the product, navigation, customization, and reliability work completed in the latest development pass—not the earlier foundation migration.
A redesigned workspace
- Rebuilt the sidebar around projects, chats, Copilot sessions, GitHub identity, and faster task navigation.
- Redesigned the chat landing page, composer, conversation-mode controls, tabs, model picker, traits picker, approval panels, and message timeline.
- Added a new Modesto wordmark, refreshed icons, cleaner menus and popovers, and a broader visual-system pass across the application.
- Simplified heavy animated and 3D surfaces in the welcome, authentication, automations, and device experiences.
- Standardized open/close motion across disclosures and collapsible regions.
Settings and customization
- Rebuilt Settings with new navigation, breadcrumbs, search coverage, panel layouts, and restore controls.
- Added a large theme catalog sourced from OpenCode and VS Code palettes, with improved previews and editor synchronization.
- Added terminal appearance controls and file-icon preferences.
- Added Copilot customization pages for preferences, palettes, skills, and session behavior.
- Added a full notification-sound library, settings, transitions, and playback coordination.
- Added dedicated Claude, Codex, and Cursor interface styles with provider-matched layouts, light/dark palettes, and preserved Modesto account controls.
Chat, artifacts, and tools
- Improved folder-free Chat and repository-scoped Work behavior throughout navigation and composer flows.
- Added stronger spawned-agent/session presentation and artifact targeting.
- Improved inline visual rendering, Canvas behavior, Markdown output, Monaco editing, and the Files panel.
- Added navigation helpers and more predictable right-panel state across Browser, Terminal, Files, Changes, Canvas, and Artifacts.
- Expanded slash-command and command-palette behavior.
Providers and models
- Redesigned provider and model selection, ordering, grouping, and availability states.
- Expanded custom OpenAI-compatible endpoint validation and model-router settings.
- Improved Codex session handling, Gemini provider behavior, ACP support, and provider command recovery.
- Added clearer provider update and model-release notifications.
Reliability and desktop integration
- Strengthened chat state transitions, approvals, handoffs, project intent, and reconnect behavior.
- Added projection persistence changes for project kinds and more reliable orchestration snapshots.
- Added desktop IPC support for native system sounds.
- Moved stable updates to a Modesto-owned feed while preserving default manifests for older Modesto installations.
