[November 13, 2026] Changes in `phyloregion` version 2.1.0.

Revised and improved the function sdm to return the evaluation threshold.
Fixed sdm() failing with algorithm = “all” (the default) and algorithm = “GLM”.
sdm() now returns the continuous habitat suitability for every algorithm in raw_habitatsuit.
Replaced the deprecated structure(.Names = ) call in phylobeta_core (CRAN check NOTE).
New functions tpd_alpha(), tpd_beta_core() and tpd_beta() compute functional alpha diversity (richness, evenness, redundancy, community weighted means) and functional beta diversity split into unique (turnover-like) and nested components, using trait probability densities for any mix of continuous and categorical traits (Carmona et al. 2016).
New functions tpd_groups() and tpd_extinction() describe the trait spectra of groups of species (for example threatened versus non-threatened) and simulate the erosion of functional diversity under extinction scenarios, with random loss of the same number of species as a null model (Carmona et al. 2021).
New vignette: Functional diversity with trait probability densities.

[July 14, 2025] Changes in `phyloregion` version 1.0.9.

Prepared and updated package for CRAN.
Revised and updated plot_pie to plot_spatial_membership and now uses blended color visualization.
Automatically adjusts radius depending on the projection system (e.g., EPSG:4326 vs EPSG:6933).
Added new functions backg, randpoints, rast_quantile, rast_hotspot
Updated documentation and examples accordingly.

Prepared and updated package for CRAN.
Revised all spatial functions to use functions in terra throughout.
Discontinued use of raster, rgeos and sp packages.
pd and beta diversity functions now accepts a community matrix of class matrix

or an phyloseq object as input.

Removed plot_evoldistinct because the functionality is replaced with plot_swatch.
plot.phyloregion and the generic plot function are now exported and both produce the same result.
Changed title to “phyloregion: R package for biogeographic regionalization and macroecology”
Improvements in the vignettes with several examples.
