Changes in version 1.4.0 (2024-04-04)                  

Major changes

  - Substantial updates to the package documentation, including both the
    vignettes and the function reference.

Minor changes

  - Deprecated the use of the add_to_tid environment variable in
    run_on_cluster().
  - Additional error handling to prevent invalid names.

                 Changes in version 1.3.0 (2023-10-26)                  

Major changes

  - Added an option for the summarize() function to calculate Monte
    Carlo standard errors and confidence intervals for all inferential
    summary statistics. For summary statistics meant to estimate a
    population quantity (e.g., the bias of an estimator), the Monte
    Carlo standard error quantifies variability due to running a finite
    number of simulation replicates.

Minor changes

  - Fixed a bug associated with function scoping; see
    https://github.com/Avi-Kenny/SimEngine/issues/92.

                 Changes in version 1.2.0 (2023-02-27)                  

Major changes

  - Added the batch() function, which allows for sharing of data or
    objects between simulation replicates. Essentially, it allows you to
    take your simulation replicates and divide them into "batches"; all
    replicates in a given batch will then share a single set of objects.
    The most common use case for this is if you have a simulation that
    involves generating one dataset, analyzing it using multiple
    methods, and then repeating this a number of times. See the
    documentation for more info.
  - Overhauled and simplified the interface of the summarize() function
    and added several summary metrics (correlation, covariance, n_reps);
    see the documentation for more info.
  - Users can now run multiple simulation replicates per core when
    running code on a CCS using run_on_cluster().

Minor changes

  - Added results of a call to sessionInfo() to vars().
  - Changed sim_id to rep_id to avoid confusion with sim_uid.
  - Removed the option for a user to specify a subset of sim_uids.
  - Removed the keep_extra option from update_sim() and
    update_sim_on_cluster().
  - Removed the .add option from set_levels().
  - Added a constraint to set_levels() to prevent changing of level
    variables once they are initially set.
  - Fixed a bug associated with functions that have a NULL environment
    (e.g. as.integer).
  - Fixed bugs that previously prevented users from running a simulation
    with no levels.
  - Various minor bug fixes.

                 Changes in version 1.1.0 (2022-04-27)                  

Major changes

  - Removed the add_* functions, as we ultimately deemed these
    unnecessary to the workflow: add_creator(), add_method(),
    add_constants(). Instead, functions declared in the parent frame of
    the new_sim() call are automatically added to the simulation object.
    It is now recommended that simulation constants are stored and
    referenced in the same way as levels; see "Advanced Usage" on the
    SimEngine website (https://avi-kenny.github.io/SimEngine/).

Minor changes

  - Fixed a bug related to the use of closures added via add_method().
  - Added more info in the documentation about how to properly load
    packages via set_config() (since this was a source of confusion
    among some users).
  - Fixed a few minor issues with the documentation.

                 Changes in version 1.0.0 (2021-09-27)                  

Major changes

  - Initial package release
