Enhanced network communication

A major focus of Roon 2.56 lies in network reliability. According to the developer, the automatic port-forwarding mechanism using UPnP and NAT-PMP has been redesigned to perform more consistently in complex or multi-router configurations. This directly benefits users running Roon Core in setups with layered firewalls or nested subnets, reducing connection dropouts and improving discovery of audio zones.

Stability improvements across all platforms

The update addresses several isolated stability issues reported by users in previous builds. These include occasional crashes under Apple macOS 26 “Tahoe,” missing audio zones after software updates, and intermittent network reconnections. Under Google Android, gesture navigation now behaves as expected again — particularly the back-swipe gesture within Roon Remote. Altogether, these refinements make the overall system experience smoother and more predictable in daily use.

Roon ARC – Efficiency and convenience refined

Released alongside the main update, Roon ARC 1.70 brings clear improvements for mobile users. The app now consumes less CPU power and battery, optimizing playback longevity on the go. Interface responsiveness has been refined, and artwork display in the “Now Playing” widget has been corrected. A new shuffle mode is now available in Apple CarPlay and Google Android Auto, giving users more flexibility while listening on the move.

Installation and update process

All systems running in the production branch of Roon will receive the updates automatically. For new installations, the latest builds are available via the official Roon download page. Updates for Apple iOS and Google Android are already submitted to their respective app stores and should appear shortly, depending on regional rollout schedules.

Price and availability

Roon 2.56 and Roon ARC 1.70 are free of charge for all existing users. The updates are distributed automatically for Roon Core, Roon Remote, and Roon ARC across all supported platforms.
