• Add family logistic_normal for simplex responses. (#1274)
• Add argument future_args to kfold and reloo for additional control over parallel execution via futures.
• Add families beta_binomial & zero_inflated_beta_binomial for potentially over-dispersed and zero-inflated binomial response models thanks to Hayden Rabel. (#1319 & #1311)
• Display ppd_* plots in pp_check via argument prefix. (#1313)
• Support the log link in binomial and beta type families. (#1316)

Other changes
