New Features

  • Support different Gaussian process kernels in gp terms. (#234)
  • Support stratified cox models via the new addition term bhaz. (#1489)
  • Support futures for parallelization in the cmdstanr backend. (#1684)
  • Add method loo_epred thanks to Aki Vehtari. (#1641)
  • Add priorsense support via create_priorsense_data.brmsfit thanks to Noa Kallioinen. (#1354)
  • Vectorize censored log likelihoods in the Stan code when possible. (#1657)
  • Force Stan to activate threading without altering the Stan code via argument force of function threading. (#1549)
  • Support moment matching loo prediction methods. (#1674)

Bug Fixes

  • Fix a bug that led to partially duplicated Stan code in multilevel terms thanks to Henrik Singmann. (#1651)
  • Fix problems with parallel executions of post-processing functions sometimes leaving unused R instances behind. Thanks to Andrew Johnson, Aki Vehtari, and Noa Kallioinen. (#1658)
  • Fix several minor bugs. (#1648, [#1644], [#1672], [#1642], [#1634], [#1666], [#1664])

Other Changes

  • Refactor some of the internal code base to avoid evaluating many data-dependent quantities several times. (#1653)
  • Smartly access internal functions when evaluating non-linear formulas. (#1635)
  • Improve the documentation in several places.
  • Make argument loo optional in loo_moment_match.
  • Change the output format of loo_predict and loo_linpred to be more consistent with other post-processing functions.
