v0.9.0

What's New

This is one of the largest releases to date — 80 commits, 514 files changed, ~33k lines added and ~22k removed. Nearly every layer of the stack has been reworked: the runtime, the agent pipeline, the CLI, the web UI, deployment, and more.

---

Architecture: Companion App Removed

The Electrobun companion desktop app has been completely removed. All execution is now consolidated to the Docker Engine API directly from the server. This eliminates an entire deployment dependency and simplifies the architecture significantly — no more companion process, no more IPC bridge, no more Bun fetch workarounds needed for the companion communication layer.

Architecture: Runtime Migration

The server runtime went through a deliberate migration cycle:

• Bun → pnpm/Node: Added a providers abstraction layer, switched the test suite to Vitest, and moved CI to pnpm.
• pnpm/Node → back to Bun: After stabilizing the provider abstraction, migrated back to Bun for its performance characteristics while keeping the cleaner architecture.

Native fetch and AbortSignal.timeout are now used everywhere — all Bun fetch workarounds have been removed.

Agent Pipeline Overhaul

• Step-based execution: The agent pipeline has been refactored to a step-based execution model with a cleaned-up tool registry. This makes the execution flow more predictable and extensible.
• Plan mode: Agents can now enter a planning mode for conversations, allowing them to reason about approach before executing.
• Experiment loop: A new loop feature for running iterative experiments within agent sessions.
• Pending responses system: Async user input is now supported — agents can request input and continue when it arrives.
• The visualizer skill and all related UI components have been removed.

CLI Refactor

The chat and telegram CLI commands have been replaced with a new, more composable set of commands:

• embed — generate embeddings
• llm — direct LLM interaction
• message — send messages
• search — semantic search

Web UI Redesign

A ground-up redesign of the web interface:

• New layouts with improved responsive behavior across screen sizes.
• JSON-based custom theme engine with a visual theme picker — users can create and switch between fully custom themes.
• Project sidebar now stays visible when navigating to admin, settings, and help pages.
• Theme cards are single-column on mobile.
• File icons are now smaller with toned-down colorization.
• Execution settings UI is hidden when execution is disabled in admin.

Spreadsheet / Table Overhaul

The CSV and Excel spreadsheet viewer has been substantially reworked:

• Overhauled table rendering and edit actions.
• Sticky row-number column with correct z-index layering.
• Sticky header overlap fixes.
• Add-row restored as a table row; add-column rendered as a matching last column.
• Fixed the add-column header collapsing to zero width.
• Virtualized scrolling fixes for the fixed bottom bar and sticky columns using inline styles.

File Explorer Improvements

• Breadcrumb navigation added — shown at root and in subfolders, replacing the old item-count summary.
• Breadcrumb positioning iterated (moved from bottom to top, then below storage summary).
• Fixed empty-folder navigation and folder-switch flicker.

Project Management Features

• Star projects: Projects can now be starred, with a star indicator shown on project cards.
• Archive projects: Projects can be archived, with an archived-projects section on the dashboard.
• Credentials UI: New interface for managing project credentials, with project settings restyled to match the admin/account layout.

Push Notifications & PWA

• Push notifications with a full notification permission flow.
• PWA manifest and service worker for installable web app support.

Telegram Refactor

• Refactored to a global bot architecture with webhook-based message delivery.
• Added user linking so Telegram accounts map to platform users.
• Fixed double-buffering issues in the Telegram runner routes.

Authentication & Collaboration

• Passkeys (WebAuthn) support for passwordless login.
• OAuth provider integration.
• Invitations system for onboarding new users.
• WebSocket connections with presence indicators for real-time collaboration.

Deployment & Infrastructure

• OCD deploy manifests: Standalone deploy manifests added for both server and runner, with iterative fixes for build context, volume paths, and schema compliance.
• CD workflow: New GitHub Actions workflow to build and push the session container image to GHCR, with fixes for org name casing, image paths, and env var keys.
• Runner deploy improvements: Docker socket mounting, SERVER_URL injection, session network connectivity fixes.

Runner & Container Performance

• Runner pool: Added a runner pool for managing multiple runner instances.
• Session container cold start optimization — significantly faster container spinup.
• OOM fixes for small VPS (4GB):
  • Streaming snapshot and blob transfers end-to-end instead of buffering in memory.
  • Skip snapshot restore when a container is already running on the runner.
  • Reduced session container memory footprint.
  • Increased Node.js heap limit to 8GB as a safety net.
  • Added RSS memory bisection logging across the workspace, container, and bash tool layers for debugging.
• Removed buffered fallback in runner restore routes.
• Added runner socket directory volume mount for session container proxy.
• Extensive logging added across the runner service and admin connection lifecycle.
• Container log capture on CDP timeout (timeout increased to 45s).
• Fixed session container startup: disabled dbus, robust socat startup.

Dark Mode & UI Polish

• Fixed dark mode contrast for markdown rendering (streamdown tables, blockquotes, inline code).
• Fixed dark mode contrast for MDXEditor tables and popovers.
• Unified toast appearance: removed icons and left border colors for a cleaner look.

Full Changelog: v0.7.1...v0.8.0

v0.7.1

What's changed

• Docker setup reworked (macOS) — Removed automatic Homebrew/Colima installation. The app now detects existing Docker installations (OrbStack, Docker Desktop, Colima) and starts the daemon automatically. Users are guided to install Docker themselves if not found.
• macOS PATH fix — GUI apps now augment PATH with /usr/local/bin, /opt/homebrew/bin, and /opt/orbstack/bin so Docker and other CLI tools are discoverable.
• Setup 2FA flow fix — Setup now issues a temporary token first, with the full JWT only granted after 2FA is confirmed. Prevents authenticated access before 2FA is complete.
• Companion artifact — macOS companion download changed from .tar.gz to .dmg.
