iOfficeAI/AionUi v2.1.61 on GitHub

Highlights

Settings → Appearance now lets you choose the typeface across four regions — app, chat, markdown and code — from a searchable list of fonts installed on your machine, plus a matching font-weight control (Light/Regular/Medium/Semibold/Bold, or system default) for each region.

The archived conversations list now pages in the rest of each group instead of silently truncating it — a "load more" button reveals older archived chats a page at a time.

The agent's plan / to-do snapshot moves out of the message stream into a collapsible bar pinned above the send box, and a bug that could duplicate the plan card while destroying a neighboring message is fixed.

The preview panel gains a maximize/restore toggle that hides the chat area and gives the preview the full width; restoring is instant.
Right-clicking a preview tab no longer opens an invisible off-screen menu, and the menu now includes Close and Close Unmodified actions (with Cmd/Ctrl+W support scoped to the panel).

The slash-command menu in the chat send box now accepts the highlighted command with Tab/Shift+Tab, and a race that could send the raw /command text instead of selecting it on fast typing is fixed.
Markdown now renders WaveDrom/WaveJSON timing diagrams inline, with the same pan, zoom and click-to-zoom interactions already available for Mermaid diagrams.

Model selection for Claude sessions is now applied the same way the Claude CLI applies it, so the app and the CLI agree on which model is actually running.
Session JWTs now last 30 days to match the cookie lifetime, avoiding unexpected re-authentication.
Plan snapshots are now persisted with the conversation so they can be restored later, and archiving a conversation properly tears down its agent process.
Skill descriptions injected into the agent context are trimmed to fit the injection budget, reducing overhead on startup.

Fixed conversations started from an empty message showing a blank, unclickable title — the title area is now always clickable to rename, even when empty.
Fixed markdown tables without explicit alignment markers rendering with a centered header above left-aligned body rows; headers now align left like the rest of the table.
Fixed a case where an unpicked model silently inherited a stale choice from a previous session instead of letting the agent start on its own default.
