Canton 0.0.8 (2026-09-22)

Require an explicit, non-empty output directory in imagesave().
Validate unsupported plot objects before creating directories.
Make setfont() validation side-effect-free; code blocks apply temporary settings restored on exit, including errors and nested calls.
Remove persistent font hooks and platform font registration.
Retain resetfont() as a documented compatibility no-op.
Add a verified reference for the ggplot2 graphics framework.
Add regression tests for state restoration and export failure handling.

Added imagesave() for saving ggplot2, pheatmap/grid, ComplexHeatmap, recorded base R, lattice, and function-generated plots in one or more formats.
Added setfont() for checked, cross-platform plotting font configuration.
Added reusable figure_preset() settings for publication, single-column, double-column, high-resolution, and presentation output.
Added theme_canton() and discrete/continuous ggplot2 colour and fill scales.
Added fontlist(), fontcheck(), and resetfont() for safer font workflows.

Fixed hue() for unknown palettes and added case-insensitive matching.
Fixed using() with no arguments and added support for strings and character vectors.
Made mkdir() idempotent and added explicit validation and useful returns.
Updated package metadata, documentation, examples, and tests.
