Changes in version 0.8.3 (2024-03-14)                  

  - Changed the parameters of functions counterfactual and fairness. Now
    the method to simulate counterfactuals must be always specified by
    the user and condition_type is required if the method is "u_find".

                 Changes in version 0.8.2 (2023-12-19)                  

  - Fixed a bug in the interventions to missingness indicators (rflist).

                 Changes in version 0.8.1 (2023-11-18)                  

  - The content of simdata and simdata_obs revised when missing data
    mechanism is present.
  - Interventions can be applied also to background variables (uflist)
    and missingness indicators (rflist).
  - Added counterfactual identification via R package cfid.
  - Added tikz as an output format.
  - Updated the method for creating the package documentation. (I do not
    really understand this but it works now.)

                 Changes in version 0.8.0 (2023-06-12)                  

  - Added function fairness for fairness evaluation via counterfactual
    simulation.
  - Added new default method "u_find" to functioncounterfactual to
    simulate counterfactuals for continuous and discrete variables.
  - Added methods to R6 class SCM to add and remove vertices.
  - Added methods to R6 class SCM to obtain parents, children, ancestors
    and descendants of a set of vertices.
  - Added R6 class LinearGaussianSCM for random linear Gaussian SCMs.
  - Added functions analytic_linear_gaussian,
    analytic_linear_gaussian_conditining to work with linear Gaussian
    SCMs.

                 Changes in version 0.7.0 (2022-11-04)                  

  - Added R6 class ParallelWorld to enable more general counterfactual
    simulations.
  - Improved output control for simulations.

                 Changes in version 0.6.1 (2022-08-06)                  

  - A minor change due to change in the igraph package.

                 Changes in version 0.6.0 (2021-08-06)                  

  - The first version submitted to CRAN.
  - Added a NEWS.md file to track changes to the package.
