Release v2.1.19 · iOfficeAI/AionUi

Highlights

This release sharpens team mode and assistants, and fixes Office preview on web-server deployments.

Stop controls are now slot-scoped: pausing one teammate no longer cancels the whole team, and each pane's send box is gated independently.
Team chats now prefer the assistant's identity (avatar/name) when one is set, and the team workspace display correctly prefers the persisted team workspace, falling back to the leader's only when empty.

Fixed assistant cron and Guid flows: cron tasks now show the right assistant avatar/name, selected skills are kept on Aionrs conversations, and assistant metadata is preserved through team creation.
Removed leftover Star Office UI remnants from the assistant area.

Stable auto-updates now read their metadata from the CDN instead of the GitHub API, for more reliable update checks and downloads, plus a desktop "report installation diagnostics" action next to "download latest" when an install looks broken.

Office (PPT/Word/Excel/CSV) preview now works on Linux server deployments — the auto-installed officecli component requires libicu, which Debian-based images (including the runtime base) don't ship, so previews were broken until now.
When officecli is missing or fails to install in web mode, AionUi now shows the exact server-side install command instead of pointing remote users at the wrong machine.

Fixed a 2.1.18 regression where a custom OpenAI-compatible STT endpoint that can't stream returned "No speech detected" — recording now keeps going and falls back correctly when streaming fails to establish.

ACP runtime model, mode, and thought-level selectors now reflect the options the backend actually advertises, and remember your preference.
Windows: local CLI agents launched from the desktop/start menu are now detected reliably (the GUI process PATH is hydrated from registry and shell profiles before startup).
Disabled custom agents stay visible (greyed, with a working re-enable toggle) in Settings → Agents instead of disappearing entirely.
The "AionUi" wordmark in the sidebar now acts as a back-to-chat / home control.
The AI message copy row no longer flickers mid-stream — it appears once the reply finishes.
