This is major release with several infrastructural changes that will make future development of dynesty easier, as well as significant speedups. The release also deprecated some rarely used options. Major refactor of the code that makes it easier to add new samplers. Major speedup of the uniform sampler when sampling in parallel You can now provide samplers as classes as arguments NestedSampler(sample=RWalkSampler(walks=44)) Convergence statistics are saved for each iteration that can help diagnose sampling issues You can now save the function evaluation history for all function calls throughout the sampling, even when doing it in parallel The Hamiltonian slice sampler was removed because of lack of proper testing and not being mantainable The notebook highlights some of the key changes.
