|a Changes in chromosome numbers are a prominent driver of plant evolution, impacting ecological diversification, stress tolerance, and phenotypes. ChromEvol is a widely used software tool for deciphering patterns of chromosome-number change along a phylogeny of interest. It evaluates the fit of alternative models to the data, estimates transition rates of different types of events, and infers the expected number of events along each branch of the phylogeny. We introduce ChromEvol v.3, featuring multiple novel methodological advancements that capture variation in the transition rates along a phylogeny. This version better allows researchers to identify how dysploidy and polyploidy rates change based on the number of chromosomes in the genome, with respect to a discrete trait, or at certain subclades of the phylogeny. We demonstrate the applicability of the new models on the Solanaceae phylogeny. Our analyses identify four chromosome-number transition regimes that characterize distinct Solanaceae clades and demonstrate an association between self-compatibility and altered dynamics of chromosome-number evolution. ChromEvol v.3, available at https://github.com/anatshafir1/chromevol, offers researchers a more flexible, comprehensive, and accurate tool to investigate the evolution of chromosome numbers and the various processes affecting it
