- Redesigned file browser navigation — configurable path bar with breadcrumb and text modes, folder autocomplete with keyboard navigation, and fully clickable file rows without a loading overlay
- Consolidated create-new dropdown replaces separate New File and New Folder buttons
- Inline rename and new-folder creation in the shared footer input row, with modal rename preserved for external callers
- Preserved file tree ancestors — parent folders stay clickable during nested navigation; starting folder is now configurable and defaults to /a0
- Canvas and picker lifecycle fixes — opening a file picker no longer blanks a live canvas listing, and live browsers navigate in place for path links instead of stacking windows
- File permissions and ownership preserved when applying editor patches — executable bits and host-user ownership are no longer replaced with root-owned 0600 files
Agent Zero by Agent Zero s.r.o.

What changed: recent Agent Zero releases
10 stable releases in the last 90 days · Full changelog
- Enforced negotiated WebSocket payload ceilings with a symmetric checksummed transfer protocol for large operations, including bounded transfer state, disk spooling, and automatic cancellation on…
- Made workspace HTTP file transfers atomic with streaming uploads into partial files, size verification, fsync, and SHA-256 download receipts
- Bounded remote connector tool payloads with explicit continuation metadata for large content, rejecting oversized inline artifacts before base64 expansion and routing bulk files to authenticated…
- Documented connector payload contracts including WebSocket ceilings, transfer state machine, cancellation lifecycle, and remote text limits
- Added independent, lazily loaded directory trees to Files and Editor in canvas and modal modes with unified styling, lighter panel backgrounds, and flat toolbar controls
- Unified text and code editing in the shared Editor with ACE syntax highlighting, line numbers, native source search, and Markdown preview — removing the legacy file-editor modal
- Context Window Usage Indicator — A bundled plugin showing a composer usage ring, responsive breakdown popover with token counts, percentages, free-space reporting, and provider-reported…
- Context Doctor — Automatically repairs malformed tool-call JSON before dispatch, handles incomplete or thoughts-only responses, supports XML suppression, and persists repaired output in WebUI…
- Vision Sidecar Integration — Strict per-preset sidecar slot with Main-first routing, one-call multi-image analysis, parallel-worker image resolution, configurable timeout/max-token controls, and…
- Result Extension Point — Extensions can now normalize or consume completed model results before default history and tool processing. Repeat detection and empty-response handling are split into…
- WebUI Plugin Slots — New extension slots beside the model/profile strip and at the end of interface visibility controls, allowing plugins to register responsive UI affordances.
- Responses now render with safe Markdown and LaTeX throughout live streaming, removing the raw-to-formatted swap at completion.
- Interactive viewport: The internal Browser now renders a live, interactive session via Xpra with CDP screencast and snapshot fallbacks, replacing static screenshot-only interaction.
- Shared runtime: All chats route through a single persistent Chromium, Xvfb, and Xpra instance. Sign-ins are shared across chats while tab ownership and limits remain per-chat.
- Bot detection hardening: Chromium now runs headful through Patchright on a private Xvfb display, significantly improving resilience against bot detection.
- Tab restore: Browser tabs are automatically persisted and restored per-chat and in shared scopes, without showing Chromium's crash advisory on restart.
- Browser model preset: The configured Browser model preset is now correctly activated after the first Browser tool call and cleared at monologue end.
- Annotation and UI improvements: Added DOM hover feedback, multi-page annotation batches, compact composer-style controls, and microphone/arrow controls in the annotation dialog.
- New Agent Editor UI with Easy and Advanced modes for editing agent identity, prompts, model presets, tool policies, skill visibility, and avatars — all without destructive overwrites or model calls.
- Project-scoped profiles: switch between Global and project scope when managing agents; sparse reads, writes, resets, and policy configs stay bound to the selected layer.
- Profile lifecycle management: per-scope availability, duplication, active-profile status, inline project selection, scoped restore for inherited profiles, and synchronized profile switching across…
- Reusable profile commands: create profiles quickly via /profile in chat or through the Connector API, then open a fresh chat with the new profile in the selected scope.
- /permissions slash command: opens the current profile's Agent Editor directly from chat.
- Tools, MCPs, and Skills get explicit default switches with segmented per-item policy controls, preserving sparse overrides.
- Stop button and /stop API — Cancel a running agent context without deleting it. The chat bar now shows a stop button while the agent is working, and a new /stop endpoint is available for…
- UI asset bundler and service worker — A new build-time bundler discovers same-origin HTML, CSS, and JS assets and delivers them as a versioned JSON bundle. A service worker pre-populates a…
- WebUI extension manifest — The bundler and server now support an extension manifest, allowing enabled extensions to inject their own entry files into the bundle. The index page is rendered with…
- Chat-naming and pin-to-top plugins — Chat renaming has been extracted from core into a dedicated chatnaming plugin with its own API, prompts, UI modal, and Utility Model integration. A new…
- Lazy chat rendering and pagination — messages.js has been refactored to support lazy rendering of chat messages, improving performance for long conversations.
- Slash commands exposed through skills — The Commands plugin now handles scoped command discovery, and the skills tool can list or read effective slash-command definitions without invoking them. A…
