V1.7.0 Changelog:

• Added auto-squelch
• Auto-gain added (note fixed gain may still best in most situations as auto gain can overload easily)
• Added ROOT-MUSIC algorithm (useful if you only need a single bearing output, but may provide poor results when used with the app)
• Various bugfixes
• Underlying code refactored

V1.6.1 Changelog:

• Fix issue with timestamping
• Add FIR order setting in web gui. Setting a higher FIR order may improve results especially when dealing with multiple narrowband signals close to one another. The trade-off is higher CPU usage.
• Add beta features for FM demod. Warning: Is beta, so demod quality is poor. Can fill up the SD card rapidly, which could result in a boot failure.
• Minor UI fixes
• Numba removed in some functions, may result in higher CPU usage, but seems to make things more stable

V1.6 Changelog:

• Various bug fixes, code refactors
• Improved logging (Credit: @godsic)
• Fix center freq bug (Credit: @redradist)
• Optimizations to the receiver memory transfer code
• Python and Numba Cache is cleared by default now to avoid corruptions or mismatches, so the first boot may take a little longer than others. This should hopefully fix the spectrum randomly freezing that some people have been seeing.
• Cleaned up apt and pip cache to save SD card space

V1.5 Changelog:

• Algorithms implemented by @godsic added. These are experimental decorrelation algorithms that could help when there is a lot of multipath. See the Decorrelation heading under https://github.com/krakenrf/krakensdr_docs/wiki/05.-KrakenSDR-Web-Interface-Controls#doa-configuration for more information.
• Fix peak-hold. Thanks @godsic
• Add num sources menu. If you know for sure that there is more than one signal on the same frequency, you can set the number of sources here. But setting it higher than the actual number of sources can cause bad results. Thanks @godsic
• Cleaned up conda install, removed a bunch of installation packages to reclaim disk space
