Changes in version 0.5.0                        

  - Add circular_regression() as the main fixed-effect modeling
    interface.
  - Add angular_two_step() as an explicit consensus-then-homogeneous
    workflow.
  - Add S3 methods for coefficients, fitted values, residuals,
    predictions, summaries, plots, log-likelihoods and information
    criteria.
  - Improve consensus numerical stability for large Bessel-function
    arguments.
  - Add validation for finite angles, non-negative modifiers, weights,
    controls and initial values.
  - Align logLik.consensus(), AIC.consensus() and BIC.consensus() with
    the full von Mises log-likelihood by including the normalizing
    constant. This changes absolute consensus likelihood and
    information-criterion values but does not change the fitted
    estimates.
  - Add summary.angular_re() and print.summary.angular_re().
  - Preserve model-frame na.action information in angular() objects.
  - Replace the draft overview vignette with two reproducible HTML
    vignettes.
  - Add pkgdown configuration and a workflow diagnostics article.
  - Add a package-data workflow vignette for R Journal reviewer support.
  - Add a minimal GitHub Actions R CMD check workflow.
  - Clarify random-effects and special-wrapper documentation.
  - Clarify documented provenance for noshiro and the remaining
    provenance limitations for multiplebison.
  - Add a related scientific reference for the multiplebison study
    context.
  - Expand tests for simulation recovery, predictions, NA handling,
    weights, modulo invariance and small-sample fits.

                        Changes in version 0.4.0                        

  - See CHANGELOG_0.4.0.md in the development repository for development
    notes. That file is not included in the CRAN build.

                        Changes in version 0.1.1                        

  - Improve stability of angular and consensus estimators with QR-based
    updates and better handling of reference-only models.
  - Implement observation weights in consensus() and remove the
    deprecated model argument across the API.
  - Make angular_re() usable without workarounds, add Hessian
    conditioning checks, and provide more robust predictions.
  - Refresh documentation and vignette examples, and add an automated
    test suite covering key model features.
