+
+### Features
+
+* azimuthal average of a centred diffraction pattern ([#39](https://github.com/mac4DSTEM/SimulatoKit/issues/39)) ([82ec3d0](https://github.com/mac4DSTEM/SimulatoKit/commit/82ec3d0bf0bc8fcf358b15c2484e7a092576435f))
+* Fourier-space image interpolation and integrateDisc(interpolate:) ([#41](https://github.com/mac4DSTEM/SimulatoKit/issues/41)) ([f39aa4b](https://github.com/mac4DSTEM/SimulatoKit/commit/f39aa4b71ca2afbe0380732c11c537a77f4fe485))
+* LineScan matched to a probe: end=None and Nyquist sampling defaults ([#40](https://github.com/mac4DSTEM/SimulatoKit/issues/40)) ([17346f9](https://github.com/mac4DSTEM/SimulatoKit/commit/17346f9c0cdf4097c90f282d1e017a6265eeb89b))
+* Poisson noise samples and frozen-phonon exit waves ([#33](https://github.com/mac4DSTEM/SimulatoKit/issues/33)) ([a40af46](https://github.com/mac4DSTEM/SimulatoKit/commit/a40af46aad8652618f0919ad750a566e69d2ea16))
+* ProjectedPotential.project and tiled, Potential.project ([#38](https://github.com/mac4DSTEM/SimulatoKit/issues/38)) ([78a6cd2](https://github.com/mac4DSTEM/SimulatoKit/commit/78a6cd250a4124d82abf90d5e0eff6390fc8e0ce))

+* Slicing.crystalSliceThicknesses, slices that follow the crystal planes ([#37](https://github.com/mac4DSTEM/SimulatoKit/issues/37)) ([4447588](https://github.com/mac4DSTEM/SimulatoKit/commit/444758803f978f6f472cc87991aeb939568dbea6))
+
+
+### Performance Improvements
+
+* generic odd-radix FFT pass for lengths with prime factors above 7 ([#45](https://github.com/mac4DSTEM/SimulatoKit/issues/45)) ([1f626b6](https://github.com/mac4DSTEM/SimulatoKit/commit/1f626b6ccee898176b7672f77efcf9f0ad9c8f67))
