DHARMa version 0.5.0 has changes in default simulations for GLMMs

Hi performance team,

Since you use the DHARMa package to calculate quantile residuals in some of your functions, we, from the DHARMa team, would like to inform you in advance that we are submitting DHARMa v0.5.0 to CRAN soon.

This new version has, among others, a major change that may interfere with your package:

• For hierarchical models (GLMMs), we changed the default simulations from the supported model's default (mostly unconditional) to conditional simulations (for most of the supported models and packages). This represents a major change in the calculated scaled residuals and is implemented to ensure higher power in dispersion and other tests. We expect different results for calculated residuals using this or older DHARMa versions. For compatibility, you can use the argument simulateREs = "user-specified" to change back to the model's default (older DHARMa versions). See the package vignette for more details.

You can check this and other changes on our GitHub.

Let me know if you need more info or help regarding this. If not, you can close the issue as you prefer.

Best,
Melina

Thanks, tests are updated and conditional on the forthcoming version.
