Changes in version 0.6.1 (2026-10-30)                  

First CRAN submission.

  - Seeded steps (simulation, re-randomisation, multiple imputation,
    robust regression) restore the caller's random-number state on exit,
    so a seed argument never changes the global stream.
  - stress_report(), stress_tables() and stress_html() have no default
    output location; nothing is written unless a directory or file is
    given.
  - stress_verdict() and tipping_point() gain examples.
  - ORCID and copyright-holder role in Authors@R; the citation reads the
    version from the package metadata.

                        Changes in version 0.6.0                        

  - standard_plan() now shifts the tipping family at the contrast visit
    unless shift_visits is given; before, an omitted shift_visits
    shifted every imputed visit, which changed the tipping estimand
    silently.
  - stress_design(): design-stage use. Simulates a planned trial over a
    grid of sample sizes and effect sizes and reports the robustness
    power (significant and robust) next to the conventional power, the
    verdict rates among significant results, the one-subject fragility,
    and optionally the deletion search and the delta-adjustment margin;
    plot() draws power and robustness power against the sample size, and
    print() names the smallest sample size that reaches a target
    robustness power.

                        Changes in version 0.5.0                        

  - stress_ranktest(): Wilcoxon rank-sum and van Elteren tests at the
    contrast visit (model-free family).

  - simulate_trial() gains heavy-tailed errors, heteroscedastic visits,
    MNAR dropout and effect modification; stress_calibrate() passes them
    through.

  - Observed-margins weighting fixed for three or more arms.

  - Reference-based imputation seeds each draw on the worker, so results
    no longer depend on the number of cores.

  - The fitter reads the model matrix and covariance parameters through
    mmrm's public accessors.

  - Verdicts, reports and tables state how many refits did not converge.

  - mask_ids() replaces subject identifiers with sequence numbers; on by
    default in stress_html().

  - run_plan() starts one worker cluster and shares it across families.

  - stress_sap() and the installed template give the
    statistical-analysis-plan text for a pre-specified stress test.

  - Validation vignette; CITATION; Nathan Hogan credited for the SAS
    reference validation.

                        Changes in version 0.4.0                        

  - Specs from an mmrm fit (stress_spec_mmrm()) and from an ADaM BDS
    data set (stress_spec_adam()).
  - Three or more arms: active chooses the comparison; stress_visits()
    gives the contrast at every visit; run_plans() runs several
    endpoints or comparisons and summarises them together.
  - standard_plan(): the recommended, citable set of families.
  - stress_estimand(): intercurrent-event strategies (treatment policy,
    hypothetical, while on treatment, composite) derived from an event
    table.
  - stress_explain(): attributes an alternative's shift to subjects.
  - Deliverables: stress_tables() (CSV, Word, RTF), stress_log() (audit
    trail with the plan's hash), stress_html() (interactive report).
  - simulate_trial() and stress_calibrate(): pre-trial calibration of
    the verdict.
  - Vignettes: quickstart, interpreting the verdict, missing data, for
    SAS users.

                        Changes in version 0.3.0                        

  - Pre-specification: stress_plan(), run_plan(), stress_report().
  - stress_weights() and the weights setting (equal versus
    observed-margins least-squares means); cLDA estimator; fast path for
    the re-randomisation test.
  - Validation: rbmi cross-check of the reference-based imputation;
    re-randomisation and cLDA gates.

                        Changes in version 0.2.0                        

  - Reference-based multiple imputation (stress_reference()), the
    sensitivity/supplementary role, the greedy deletion search
    (stress_fragility()), the estimator-class family
    (stress_estimator()).

                        Changes in version 0.1.0                        

  - Engine, nine families, census, verdict and the three displays;
    validated against a SAS robustness package.
