Arc 1.9.6
Arc 1.9.6 gives replies the full conversation width and prevents managed agents from posting the same final answer twice in one turn.
Current release
Replies that read clearly
Windows 10/11 (64-bit), or macOS 11+ on Apple Silicon. Bundled Local AI requires macOS 26+.
Fixes and refinements
- Replies stay readable with the sidebar open or interface zoom increased. Copy, retry, and edit controls, expanded menus, and edit panels sit below the message.
- When a managed agent posts an answer and repeats it in its final response, Arc reuses that turn’s existing message while preserving file links and retry history. Distinct updates and later replies remain separate.
System requirements
Windows 10/11 (64-bit), or macOS 11+ on Apple Silicon. Bundled Local AI requires macOS 26+.
