Changes in version 1.1.0 (2025-11-21)                  

Function adjustments

  - simdata() now includes the new jitter.base parameter, which allows
    controlled stochastic perturbations of site-level parameters. This
    feature increases variability among simulated communities,
    particularly in nested designs (e.g., sites within regions), where
    previous versions tended to generate unrealistically similar
    communities. By applying mild randomness to occurrence and abundance
    probabilities, simdata() produces simulated data sets with
    multivariate dispersion closer to empirical expectations.

  - The use of jitter.base is optional (default jitter.base = 0), so
    existing workflows remain unchanged. Users who wish to reproduce the
    behavior of earlier versions can simply ignore this parameter. For
    reproducibility, remember to use set.seed() before calling
    simdata().

                 Changes in version 1.0.2 (2025-04-24)                  

Changes requested by CRAN

  - Updated cross-references in .Rd files to use explicit package
    anchors (e.g., \link[ggplot2:ggplot2-package]{ggplot2}) as requested
    by the CRAN team.
  - Removed all \link{} usages without package anchors in documentation
    files.
  - Ensured compatibility with HTML reference manuals.

Documentation improvements

  - All .Rd documentation files were migrated to the roxygen2 format.
  - Improved consistency and accuracy in the documentation of function
    arguments and outputs.
  - Added missing imports in the NAMESPACE to fix visibility issues
    (ggplot, geom_point, specnumber, etc.).
  - Removed unused @importFrom tags and documented only necessary
    dependencies.

Code adjustments

  - Replaced use of rel() in plot_ssp() to avoid dependency on
    grid::rel, which is not exported.
  - Reformatted long lines in examples to comply with
    CRAN’s 100-character limit.

Testing and validation

  - devtools::check() returns 0 errors | 0 warnings | 1 notes (only
    minor ones related to timestamp verification).
