gghdx 0.2.0

• Incorporate the 2025 HDX website redesign into the package’s colors, fonts, and default theme.
• Add the primary, brand, neutral, success, warning, and error color scales from the new HDX design tokens to hdx_color_list, accessible through hdx_colors(), hdx_hex(), and hdx_color_names(). The original sapphire, mint, tomato, and gray scales are kept for backwards compatibility. hdx_color_names() and hdx_hex() now cover all 94 legacy + 2025 color names (previously 17); hdx_colors() still defaults to just the original 17 for backwards compatibility, unless specific scales are requested.
• Add hdx_pal_primary(), hdx_pal_brand(), and hdx_pal_error(), along with matching scale_color_hdx_...(), scale_fill_hdx_...(), and scale_..._gradient_hdx_...() functions, superseding hdx_pal_sapphire(), hdx_pal_mint(), and hdx_pal_tomato() respectively.
• Add load_hdx_fonts() to load Merriweather (display/title font) and Roboto (body font), replacing Source Sans 3 as the package’s default fonts. load_source_sans_3() is kept for backwards compatibility.
• Update theme_hdx() with a new title_family argument (default "Merriweather") applied to titles, subtitles, and strip text, while base_family (default "Roboto") applies to body text. Gridlines, axis lines, and ticks now use the new hairline gray, and axis text uses the new muted gray. If only base_family is supplied, title_family now follows it automatically instead of defaulting to "Merriweather", so pre-2025 code such as theme_hdx(base_family = "Source Sans 3") continues to work without also loading Merriweather.
• Update hdx_geom_defaults() so points, lines, and other default geometries use the new primary blue, and area/bar/ribbon fills use the new institutional data-grid blue, instead of the original sapphire/mint colors.
• geom_text_hdx() and geom_label_hdx() now default to the Roboto font family instead of Source Sans 3.
• Add a design = c("2025", "legacy") argument to gghdx(), theme_hdx(), hdx_geom_defaults(), and hdx_pal_discrete() (and a matching design argument on scale_color_hdx_discrete()/scale_fill_hdx_discrete()). design = "legacy" restores the exact pre-2025 theme, geometry defaults, and 12-color discrete scale, since much unpinned downstream code depends on this package’s defaults and previously had no way to opt back out of the redesign.
• title_family and design were appended at the end of the theme_hdx() and gghdx() argument lists (after horizontal), preserving the original positional argument order so existing positional calls like theme_hdx(10, "sans", FALSE) still work as before.
• Update maintainer in DESCRIPTION to Giulia Martini. Since this changes the CRAN maintainer contact, coordinate with Seth Caldwell in advance of the next CRAN submission, as CRAN will email the account listed at submission time for confirmation.
• Add a design = c("2025", "legacy") argument to geom_text_hdx() and geom_label_hdx() so design = "legacy" uses Source Sans 3 instead of hardcoding Roboto, completing the design = "legacy" escape hatch for plots using text or label geoms.
• Move design after ... in scale_color_hdx_discrete() and scale_fill_hdx_discrete(), fixing the same positional-argument hazard already fixed in theme_hdx()/gghdx() (e.g. scale_color_hdx_discrete("red", "Legend name") no longer binds "Legend name" to design).
• Improve the error raised when a font isn’t loaded to mention the 0.2.0 default font change and point at load_hdx_fonts() or design = "legacy".
• Tests, examples, and the vignette no longer fail when Merriweather, Roboto, or Source Sans 3 can’t be downloaded from Google Fonts (e.g. no internet connection or the curl package is unavailable); they now skip or fall back to sans instead.

gghdx 0.1.4

• Export number_hdx() to provide users simple access to number formatting outside the labeling use case.

gghdx 0.1.3

• Implement label_number_hdx() function to improve numeric scales labeling to match the data visualization guidelines.
• Switch develop continuous NA fill value to be "transparent" so it appears better when plotting continuous rasters.
• Check installed {ggplot2} version to pass the scale_name argument to remove warnings and errors.

gghdx 0.1.2

• Use anonymous function format function() in hdx_display_pal().
• Add gghdx_reset() and ggplot2_geom_defaults() functions to allow user to remove all defaults set by gghdx().
• Improve load_source_sans_3() so local installations of Source Sans 3 are used when an internet connection is unavailable.
• Update tests to not break with release of {ggplot2} 3.5.0.

gghdx 0.1.1

• Switched base font family from Source Sans Pro to Source Sans 3.
• Fixed links flagged in CRAN checks.
• Revamped all documentation for clarity and ensuring return values and examples are provided, based on CRAN review.
• First CRAN release, as we have reached some stability!

gghdx 0.1.0

• Right adjusting y-axis labels in theme_hdx().
• Replace deprecated size argument from ggplot2 calls.
• Move ultra-light colors to end of hdx_pal() discrete palette.
• Make output of hdx_hex() unnamed to avoid errors in ggplot2 and allow both grey and gray spellings of colors.
• Change ..._gradient_... scale functions to have white as the low color.
• Add display_hdx_pal() function to allow visualizing the HDX color palettes.
• Improved error catching when fonts are not available.
• Added gray color palette, hdx_pal_gray().

gghdx 0.0.2

• Cleaned df_covid for consistent days between dates on x-axis plots.
• Changed NA colors from white to gray.

gghdx 0.0.1

• Added a NEWS.md file to track changes to the package.
• Implemented scale_fill...() and scale_color_...() functions for easy application of HDX palette to aesthetics and hdx_colors(), hdx_pal(), and hdx_hex() for user access.
• Released theme_hdx().
• Added gghdx() to apply session level defaults for plotting.
• Developed default text plotting through geom_text_hdx() and geom_label_hdx().
• Built vignette and main README.md.
