Changes in version 0.2.2                        

  - Change default value of argument max_shifted_ratio from 2 to 5
    throughout.
  - Bump up minimum versions of dependencies sl3, hal9001, and
    haldensify.

                        Changes in version 0.2.1                        

  - Change all instances of default shift being shift_additive_bounded
    to use shift_additive instead, since the former is incompatible with
    the simpler identifying functional under the modified treatment
    policy definition.

                        Changes in version 0.1.9                        

  - Change Spec_shift object to use point treatment helpers from tmle3.
  - Support missing data functionality based on updates to tmle3.
  - Change conditional density estimation in tests and vignettes to rely
    on Lrnr_density_semiparametric over Lrnr_haldensify to reduce time.
  - Remove reliance on Lrnr_rfcde since package appears unstable.

                        Changes in version 0.1.8                        

  - Change default for MSMs to use identity-based weighting over
    variance-based, improving stability of estimates.
  - Bug fixes for cross-validation: cv_fold -> fold_number.

                        Changes in version 0.1.7                        

  - Addition of cvtmle = TRUE in Updater objects as the default.
  - Bug fixes to bounding of conditional densities at the natural
    exposure value.
  - Tweaks to cvtmle option and fold_number argument to match tmle3
    updates.

                        Changes in version 0.1.6                        

  - Addition of HAL-based conditional density estimation as an option.
  - Addition of random forest-based conditional density estimation as an
    option.
  - Addition of bounding to Spec objects for variable importance
    measures.
  - Addition of bounding for conditional density and likelihood objects.
  - Minor bug fixes, including to vignettes.

                        Changes in version 0.1.5                        

  - An initial stable release of the package.
