brms 2.11.0

New Features

• Support grouped ordinal threshold vectors via addition
  argument resp_thres. (#675)
• Support method loo_subsample for performing approximate
  leave-one-out cross-validation for large data.
• Allow storing more model fit critera via add_criterion. (#793)

Bug Fixes

  sample_new_levels = "uncertainty" thanks to Dominic Magirr. (#779)
• Fix problems when using pp_check on
  censored models thanks to Andrew Milne. (#744)
• Fix error in the generated Stan code of multivariate
  zero_inflated_binomial models thanks to Raoul Wolf. (#756)

  argument subset thanks to Ruben Arslan.
• Fix out-of-sample predictions of AR models when predicting
  more than one step ahead.
• Fix problems when using reloo or kfold with CAR models.
• Fix problems when using fitted(..., scale = "linear") with
  multinomial models thanks to Santiago Olivella. (#770)
