Quoi de neuf dans la dernière version ?

• TNC selection view: Make it possible to manually configure TCP KISS TNCs by entering an IP address and a port (or a hostname and a port).
• New real-time oscilloscope in the software AFSK modem. Implemented with Metal/GPU so that the CPU usage is not affected noticeably. Refresh time (T) and decay (D) buttons adjust the scope.
• Waterfall! Now when the modem scope runs on the GPU, we can have a hardware accelerated waterfall view, too. Tap the OSC / WF button to switch between scope and waterfall. Waterfall is disabled on older hardware which does not support the current GPU acceleration configuration.
• Remove audio sample format conversions in the software AFSK modem.
• Slightly smaller CPU use when the software AFSK modem is running in the background.
• Fixed two different crashes seen in the wild (once each)
• Localisation updates: NL, JA. Thank you!
