> **This is the final AionUi build distributed through GitHub Releases.** From here on, installers and updates come from the official website. See [A note on distribution](#a-note-on-distribution) at the bottom for what this means for you, your data, and the open-source repo.

##### Highlights

###### In-App Browser, Controllable by the Agent

- Web pages now open as tabs in the preview panel, and you share one persistent session with the agent — sign in by hand once, and the agent carries that session into whatever it does next.
- The agent reaches the browser through a new built-in MCP server (`aionui-browser`), so it can navigate, click, and pull data on its own.
- On safety: the obvious way to let an agent drive Chromium is `--remote-debugging-port`, but that switch is application-wide with no per-target ACL — it would expose *every* WebContents, including the main window and its preload bridge, to any local process with no authentication. Instead this ships a single-target CDP bridge that exposes only the browser view. Nothing is written to config or the database; the bridge's port and access token travel down the process-inheritance chain, so multiple app instances never cross wires.

###### Conversation Forking

- A branch arrow on the message hover row forks the conversation at that message into a new one and drops you into it — useful for exploring a different path without disturbing the original.
- Where the entry appears follows what the backend can actually do: Codex can fork at any turn, Claude and ACP agents fork at the latest message only (so the copied history matches what the forked session really remembers), and agents without a fork surface don't show the entry at all.

###### Agent-Driven Conversation Naming

- Agents that support it now propose conversation titles automatically. A name you set yourself is never overwritten — only default and derived names stay replaceable.

###### Fixes & Improvements

- The message anchor rail introduced in v2.1.46 now stays clear of message text and covers the full conversation history.
- Database rebuild is gated behind a second confirmation, so a misclick can't wipe your local data.
- GPU-process crash noise is suppressed, and the app now tells you when hardware acceleration has been auto-disabled. The underlying crashes come from end-of-life GPUs with very old drivers rather than a code regression, and the misleading crash reports made that hard to see.
- The workspace toggle stays in the title bar where it belongs.
- Team run state handles omitted slot work instead of getting confused by it.
- Preview file I/O migrated to ChatFileRef `/content` endpoints; PDFs now load via a stream URL, and Office files resolve through ChatFileRef.

###### Engine updates (AionCore v0.1.57 → v0.1.58)

- Conversation forking and agent-driven session naming are backed end-to-end here — the backend half of both features above.
- Claude session cost now stays cumulative across process respawns instead of resetting.
- Progress cards settle correctly through session teardown and resume. Previously, if the idle reaper removed a task mid-flight while the underlying work kept running, the stored row stayed `running` — leaving a View Steps spinner turning for hours over a task that had already succeeded.
- Resumed conversations keep the thought-level picker.
- The managed Node version probe now retries transient failures instead of giving up on the first miss.

##### A note on distribution

AionUi and its commercial counterpart share a package name but use different signatures, and operating systems refuse overwrite installs across signatures. In-app updating simply cannot carry you across, so this build ships in "discontinued mode": startup auto-checks are silenced, and the manual update check opens a migration letter pointing to the official website instead.

**When you do move over:**

- **Your conversations and files stay local.** The agent runs on
