-Maximization mode for a larger waterfall and spectrum. -Squelch on the main screen. -The last selected frequency remains selected after restarting the application. -Noise reduction controlled by the NR knob has been adjusted for all clients, except for KiwiSDR/Web-888, where a dedicated control remains. -The app reopens on the receiver and client you last used. -OpenWebRX: Band chip on the spectrum - tap to see and switch the receiver's profiles. Tuning arrows stay within the current band. -Free version: S-meter dBm no longer wraps with larger system fonts. -Fixed a crash on iPhone that could make the app freeze and then close, especially while playing audio in the background.
