ggcircular 0.1.0 (2026-06-04)

New features

• Added rose diagrams, circular density estimates, mean direction layers, circular scales, circular coordinates, movement helpers and simulated datasets.
• Added circular summaries, confidence intervals, Rayleigh and Watson-Williams helpers, and theoretical circular distribution overlays.

Experimental

• Added angular model diagnostics and optional helpers for CircularRegression.
• Added exploratory finite mixtures of von Mises distributions.
• Added optional helpers for momentuHMM, spherical summaries and posterior circular draws.
• Added repository support files for contributions, support and conduct.

Documentation

• Added a README with badges, examples and a package logo.
• Added pkgdown reference pages and articles for the main workflows.
• Added CRAN readiness notes to the README, validation vignette and cran-comments.md.

Validation

• Added testthat coverage for angle utilities, summaries, ggplot2 layers, diagnostics, movement helpers, circular tests, spherical/posterior helpers and von Mises mixtures.
• Added strict momentuHMM alignment checks to prevent silent truncation.
• Added a strict hard-dependency CI profile with _R_CHECK_FORCE_SUGGESTS_ set to false.

Known limitations

• Advanced model diagnostics, von Mises mixtures and optional ecosystem integrations are experimental.
• Automatic circular-density smoothing is heuristic.
• CRAN submission is planned after additional validation and dependency checks.
