Changes in version 0.3.0 (2025-11-23)                  

NEW FEATURES

  - New function: annotation_graticule()
    Adds a projection-aware global graticule system with customizable
    spacing, labeling, and automatic antimeridian handling.

MAJOR IMPROVEMENTS

  - Major redesign of geom_world()
    Fully rebuilt global basemap system with bundled world polygons,
    coastlines, and boundaries; improved antimeridian handling; more
    reliable behavior under complex projections; and clearer, more
    consistent styling controls.

  - Major redesign of the external data workflow (check_geodata())
    The data-management system has been rewritten to meet CRAN size
    limits and improve reliability. Required datasets are now located or
    retrieved automatically using a priority search (local directories →
    package extdata → user cache), with retry, resume, mirror fallbacks,
    and fully graceful failure. All mapping functions now call this
    workflow internally.

IMPROVEMENTS

  - More robust CRS parsing, including reliable extraction of lon_0 from
    PROJ strings.
  - Better stability with coord_sf(), especially for global projections
    and shifted central meridians.
  - Updated documentation and examples, including usage of the new world
    dataset (world_countries.rda, world_coastlines.rda,
    world_boundaries.rda).
  - More consistent rendering across projections such as Robinson,
    Mollweide, and shifted longitude systems.
