◉ A new look: the app now follows Apple's own iOS design, in light and dark mode, on the iPad and the iPhone

◉ The band plan is shown on the Panadapter as a coloured ribbon
◉ Demo radio: try the app without a radio
◉ FlexRadio firmware 4.3: FreeDV modes FDVU / FDVL, filter presets from the radio (editable in the radio settings), advanced DSP settings, Auto AGC-T, Noise Floor Range, PTT Override and CW profiles (depending on the radio's licence)
◉ The radio keeps playing in the background, for example with the iPad cover closed or the screen locked
◉ Fixed: the audio didn't come back after a phone call or after opening the iPad cover
◉ FT8-Improved and JS8 work with a transverter (for example 2 m): they no longer switch the radio to a band it doesn't have

◉ PSK Reporter: changing the time, band or mode in the filter loads the list again
◉ Logbook: QSL "sent" marks of the iCloud log are no longer lost after an app update
