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) Improvements - Synchronize the iTerm color palettes with upstream (#79). This update adds 36 new palettes to iterm_palettes(): Aizen variations, Cursor Light, Dalton Dark, Dogxi Misty, Kanagawa Lotus, Kanso variations, Modus variations, Monospace variations, Onenord variations, Pierre variations, SeedFlip variations, and Sunset 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. Changes in version 4.2.0 (2025-12-17) Improvements - Synchronize the iTerm color palettes with upstream (#75). This update adds 8 new palettes to iterm_palettes(): branch, No Clown Fiesta variations, novmbr, One Dark Two, owl, traffic, and urban. These palettes are now usable by pal_iterm(), scale_color_iterm(), and scale_fill_iterm(). Changes in version 4.1.0 (2025-10-25) Improvements - Synchronize the iTerm color palettes with upstream (#72). This update adds 8 new palettes to iterm_palettes(): Hot Dog Stand variations, Matte Black, Poimandres variations, and Selenized Black. These palettes are now usable by pal_iterm(), scale_color_iterm(), and scale_fill_iterm(). Additionally, the color values for 40+ existing iTerm palettes have been updated to match the latest upstream color specifications. Documentation - Add the ggsci iterm palettes microsite link to vignette("ggsci") (#70). This microsite helps users preview all iTerm color palettes available in ggsci. Changes in version 4.0.0 (2025-09-23) New features - Add the Primer design system (from GitHub) palette in scale_color_primer() and scale_fill_primer() (#62, #63). - 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). - Use standard static imports workflow (#58). Changes in version 3.2.0 (2024-06-17) New features - Add the Observable 10 palette in scale_color_observable() and scale_fill_observable() (#41). - Add Bootstrap 5 color palettes (continuous) in scale_color_bs5() and scale_fill_bs5() (#18). - Add Tailwind CSS color palettes (continuous) in scale_color_tw3() 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) New features - 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 - Remove scale_name from all discrete_scale() calls because the 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. Changes in version 2.9 (2018-05-14) Improvements - New URL for the documentation website: https://nanx.me/ggsci/. Changes in version 2.8 (2017-09-30) Improvements - Use system font stack instead of Google Fonts in vignettes to avoid pandoc SSL issue. Changes in version 2.7 (2017-06-12) New features Two new discrete color palettes: - JAMA - Tron Legacy One new collection of continuous palettes with 19 color options: - Material Design Changes in version 2.4 (2017-03-08) New features Four new discrete color palettes: - NEJM - LocusZoom - IGV - Star Trek Changes in version 2.0 (2016-11-21) New features Two new discrete color palettes: - D3.js (v3) - Futurama (Planet Express) The first continuous color palette: - GSEA GenePattern Changes in version 1.0 New features Eight discrete color palettes (2016-04-01): - NPG - AAAS - Lancet - JCO - UCSCGB - UChicago - The Simpsons (Springfield) - Rick and Morty (Schwifty)
