sdrangel (3.11.0-1) unstable; urgency=medium
* AirspyHF: support
* RTL-SDR: refactored 8 bit samples shifting during decimation
* Refactored 8 bit samples shifting during decimation (RTL-SDR and HackRF Rx)
* RTL-SDR: implemented RF filter control (tuner bandwidth)
* GUI: show REST API URL in about dialog
