Arc 1.6.1
Arc 1.6.1 warns before likely credentials are sent, adds operator retraction for room and direct messages, and keeps current room state reliable through reconnects and storage changes.
Previous release
Safer messages, steadier room state
Windows 10/11 (64-bit), or macOS 11+ on Apple Silicon.
Highlights
- The composer checks a focused set of high-confidence credential patterns before send, then offers Review or an explicit Send anyway choice.
- Operators can retract their own room or direct messages. Arc replaces the current body with a tombstone and removes its attachment references.
- People, Work, Receipts, and room state rebuild from current authority after a disconnect, daemon restart, or storage replacement instead of accepting stale results.
Fixes and refinements
- Current-state responses are tied to the requested room and the exact running daemon generation and storage identity, with clear retry paths when that authority changes.
- Windows storage replacement now handles 64-bit file identities accurately even when their numeric index is larger than JavaScript can represent exactly.
System requirements
Windows 10/11 (64-bit), or macOS 11+ on Apple Silicon.
