What is new in PeerBrush 0.30.1

- The macOS disk image shows PeerBrush next to Applications. Drag the app to Applications, then open the installed copy.
- On first launch, PeerBrush asks whether it should open PSD and PSB files by default. Choose **Not now** to keep your current editor. You can reopen the choice from **File → PSD/PSB default editor…**.
- macOS handles any required system confirmation. On Windows, PeerBrush opens Default apps for the final choice. On Ubuntu, PeerBrush uses the file handler registered by the DEB package.
