-- Added an internally used piecewise barycentric Lagrange interpolator class
+- Added an internally used piecewise barycentric Lagrange interpolator (BLI) class
 - Added use of `shgofast` Python module for increased performance in SHGO.
 - Add notebook `A13-Gamma-Landscape.ipynb` that implements the point-of-interest
   (POI) sampling toy model.
+- Allow switching of PDF backend (explicit / BLI / Simpson).
+- Added CITATION.cff.
+- Added optional naive MPMath implementation of the posterior for crosschecking
+  purposes.
+- Check whether heat flow anomaly posterior is normalizeable.
+- Added facility to query internal state of `HeatFlowAnomalyPosterior`.
+- Add a function to compute the $P_{H,\mathrm{max}}$ possible throughout all permutations.
+- Added function `determine_restricted_samples` to determine fully (if possible)
