Highlights
Internationalization & Right-to-Left (RTL) Support
- Persian (fa-IR) now renders with a full right-to-left layout — mirrored icons, panels, and reading direction across the entire app.
- Numbers, dates, and times now format according to the language you chose inside AionUi, not your OS locale — no more mismatched currency symbols or unexpected date orders.
- Filled in dozens of missing translations across French, German, Spanish, Portuguese and more; component strings in dropdowns and dialogs now render correctly in 11 of 13 supported languages instead of 5.
- Counted text (e.g. "1 file changed") now uses the correct plural form for each language, including Russian and Ukrainian's three-way plural rules.
- Scheduled task titles and file sizes now use locale-aware date and number formats instead of a hardcoded format.
Custom Theming
- Themes can now define a validated set of color tokens for light and dark mode, and a new custom-theme guide walks you through building your own. Try the bundled Neo-Brutalism example under Settings → Appearance.
Markdown Preview: Math Formulas
- Multi-line LaTeX/KaTeX math blocks in the file preview viewer no longer break apart mid-formula — math now renders cleanly in one piece.
Team Mode Improvements
- Added a model-refresh button next to the model picker, so a model switch made elsewhere is reflected immediately in the session.
- Added a runtime-restart control that rebuilds an agent's process to pick up configuration changes while keeping the chat history.
- Team leads can now clear a member's context with
/clear, and read all of a member's queued messages together instead of being interrupted one message at a time. - Team members now get their own bound MCP tools, matching regular sessions.
- A member's selected model now persists, and leads can interrupt a member's current turn and immediately send a new instruction.
- Fixed team members occasionally getting stuck in a "processing" state.
Engine Updates (AionCore v0.1.69)
- Claude tool-call steps are now labeled by what they actually do, making it easier to follow along in the conversation as tools run.
Bug Fixes
- Fixed AionUi's internal
PREBUILDS_ONLYsetting leaking into agent subprocesses, which could crash third-party CLIs (such as cursor-agent) with a "No native build was found" error on startup. - Fixed inconsistent send/draft action button colors in dark mode and removed a stray background artifact around the send button.
- Fixed directory paths in system settings being misaligned for left-to-right languages after a previous RTL fix.
