Last week the latest version of simmer was released on CRAN: v3.1.1.

This version allows adding attributes to arrivals (and basing decisions on their values).

Also, the rollback activity was introduced, enabling you to roll back a trajectory with n steps.

In addition, a new priority param for the seize() command was introduced. This allows ordering a resource queue based on the arrival’s seize priority.

Check the vignettes on simmer’s CRAN page to get started.
