                 Changes in version 5.1.0 (2026-06-26)

Documentation

  - Fix the GenePattern HeatMapImage documentation link used by
    rgb_gsea() (#89).

Maintenance

    (#87).

                 Changes in version 5.0.0 (2026-04-17)                  

New features

  - Add Gephi generative discrete color scales for an arbitrary number
    of categories via gephi_palettes(), pal_gephi(),
    scale_color_gephi(), and scale_fill_gephi() (#82).
    
    This adds 17 presets adapted from Gephi's palette engine to generate
    visually distinct category colors on demand. Since the generator
    respects R's current random number state, call set.seed() before
    plot evaluation for reproducible results.

                 Changes in version 4.3.0 (2026-04-09)

    Drive. These palettes are now usable by pal_iterm(),
    scale_color_iterm(), and scale_fill_iterm().
    
    Additionally, the color values for Cursor Dark have been updated to
    match the latest upstream color specifications, and the Builtin
    Solarized Dark and Light palettes have been removed.

    variations, Matte Black, Poimandres variations, and Selenized Black.

                 Changes in version 4.0.0 (2025-09-23)                  

New features

  - Add the Atlassian Design System palette in scale_color_atlassian()
    and scale_fill_atlassian() (#64).
  - Add 400+ iTerm palettes in scale_color_iterm() and
    scale_fill_iterm() (#67).

Improvements

  - Add example_scatterplot() and example_barplot() to simplify discrete
    scale examples in documentation. This reduces boilerplate code and
    makes it easier to maintain the examples. Also improves graphical
    appearance of the examples by using a minimalist theme with
    alternative data subsets (#61).

Maintenance

  - Refactor the logo generation script from an R script to a shell
    script and move it into tools/ (#66).

    and scale_fill_tw3() (#19).

Improvements

  - Move internal color palette data from R/sysdata.rda to R/palettes.R.
    This change enhances package development transparency, reduces
    unnecessary indirection, and simplifies contributions by avoiding
    the construction of the palette data using the R script in data-raw/
    (#42).
  - For continuous palette examples, remove the reshape2 dependency and
    use more compact grid layout to reduce output image size (#45).

                 Changes in version 3.1.0 (2024-05-21)

  - The BMJ color palettes are implemented in scale_color_bmj() and
    scale_fill_bmj() (thanks, @huichen99, #32).

Documentation

  - Convert Rd syntax to Markdown in roxygen2 documentation. This
    simplifies documentation formatting and makes it much easier to add
    new color scales for contributors (#35).

                 Changes in version 3.0.3 (2024-03-25)                  

Improvements

  - Detect ggplot2 version at runtime to determine if the argument
    scale_name is needed for all discrete_scale() calls. This ensures
    ggsci always works regardless of the ggplot2 version installed
    (thanks, @flyingicedragon, #29).

                 Changes in version 3.0.2 (2024-03-18)                  

Improvements

    argument has been deprecated in ggplot2 3.5.0 (thanks, @DanChaltiel,
    #25).

                 Changes in version 3.0.1 (2024-03-02)                  

Improvements

  - Expand the FAQ vignette to include a solution for customizing color
    selection and ordering in a palette with self-defined color scale
    functions (#23).
  - Fix "lost braces" check notes on r-devel by using Unicode characters
    (nanxstats/ggsci@a91faf1).

                 Changes in version 3.0.0 (2023-03-08)                  

New features

  - Added three Flat UI color palettes in
    
      - scale_color_flatui()
      - scale_fill_flatui()
    
    and one color palette inspired by the logo of frontiers.org in
    
      - scale_color_frontiers()
      - scale_fill_frontiers() (thanks, @clarajegousse, #14).

  - Added three COSMIC color palettes in
    
      - scale_color_cosmic()
      - scale_fill_cosmic()
    
    (thanks, @jhrcook, #5, #7).

Improvements

  - Use a proper, three-component version number following Semantic
    Versioning.
  - Reduce output figure size in vignettes and README.Rmd by switching
    to the ragg PNG device and using pngquant for compression.
  - Added a new vignette on frequently asked questions.
      - A simple solution to interpolate the color palettes when the
        data has more categories than the number of colors in a discrete
        color scale.
      - A note on using a color scale consistently for multiple ggplot2
        plots by setting global options (thanks, @DanChaltiel, #13).
  - Replace size with linewidth in code examples for ggplot2 >= 3.4.0.
  - Replaced the previous logo with a new hex sticker logo.
  - Replaced previous CI/CD solutions with GitHub Actions workflows.
  - Fixed broken or moved links in function documentation and vignettes.
  - Removed the LazyData field from DESCRIPTION.

Improvements

  - Use system font stack instead of Google Fonts in vignettes to avoid
    pandoc SSL issue.
