Breaking changes:
* `predictions` returns predictions for every observation in the original
dataset instead of `newdata=datagrid()`.
* `marginalmeans` objects have new column names, as do the corresponding `tidy`
and `summary` outputs.
New supported packages and models:
* `brms::brm`
* `rstanarm::stanglm`
* `brglm2::brmultinom`
* `MASS::glmmPQL`
* `aod::betabin`
Misc:
* `datagrid` function supersedes `typical` and `counterfactual` with the `grid.type`
argument. The `typical` and `counterfactual` functions will remain available
and exported, but their use is not encouraged.
* `posterior_draws` function can be applied to a `predictions` or a
`marginaleffects` object to extract draws from the posterior distribution.
* `marginalmeans` standard errors are now computed using the delta method.
* `predictions` standard errors are now computed using the delta method when they are not available from `insight::get_predicted`.
* New vignette on Bayesian models with `brms`
* New vignette on Mixed effects models with `lme4`
* If the `data.table` package is installed, `marginaleffects` will automatically use it to speed things up.
* Contrast definition reported in a separate column of `marginaleffects` output.
* Safer handling of the `type` argument.
* Comprehensive list of supported and tests models on the website.
* Many bug fixes
* Many new tests, including several against `emmeans`
