+  `sdr.h1()`, `sdr.p_d()`, `sdr.p_fa()`, and `sdr.threshold()`.
+- Added support for real/complex signals and linear/square-law detectors to `sdr.non_coherent_gain()`.
+- Added calculation of minimum required SNR to achieve specified detection performance in `sdr.min_snr()`.
+- Added Peebles's approximation of non-coherent gain using a square-law detector in `sdr.peebles()`.
+- Renamed `sdr.h0_theory()` to `sdr.h0()`.
