New Features

  • Support regression splines with fixed degrees of freedom specified via s(..., fx = TRUE).
  • Reuse user-specified control arguments originally passed to the Stan backend in update and related methods. (#1373, [#1378])
  • Allow to retain unused factors levels via drop_unused_levels = FALSE in brm and related functions. (#1346)
  • Automatically update old default priors based on new input when when updating models via update.brmsfit. (#1380)
  • Allow to use dirichlet priors for more parameter types. (#1165)

Other Changes

  • Improve efficiency of converting models fitted with backend = "cmdstanr" to stanfit objects thanks to Simon Mills and Jacob Socolar. (#1331)
  • Allow for more O1 optimization of brms-generated Stan models thanks to Aki Vehtari. (#1382)

Bug Fixes

  • Fix problems with missing boundaries of sdme parameters in models with known response standard errors thanks to Solomon Kurz. (#1348)
  • Fix Stan code of gamma models with softplus link.
  • Allow for more flexible data inputs to brm_multiple. (#1383)
  • Ensure that control_params returns the right values for models fitted with the cmdstanr backend. (#1390)
  • Fix problems in multivariate spline models when using the subset addition term. (#1385)
