Functions for break number\ndetection using the approximate marginal likelihood and WAIC\nare also provided. Version 1.1.0 includes high-performance C++\nimplementations via Rcpp/RcppArmadillo for 5-15x faster MCMC\nsampling, along with modern ggplot2-based visualizations with\ncolorblind-friendly palettes.",
