Changes in version 0.19.2 (2026-03-10)                 

  - Add experimental visualization functions: gf_resid_fun(),
    gf_square_resid_fun(), gf_sd_ruler(), gf_squareplot(),
    show_cutoffs(), and outer().
  - Rename gf_squaresid() to gf_square_resid() with deprecation warning
    for the old name.
  - Add coursekata.check_missing option to control the missing-package
    install prompt, with automatic suppression on Emscripten/WASM
    environments.
  - Add tidyverse-style conflict reporting on startup, showing which
    coursekata exports mask objects from other packages.
  - Relax ggplot2 version constraint to >= 3.5.2 to support
    Emscripten/WASM environments.
  - Improve performance of estimate extraction functions by bypassing
    supernova when using default arguments.

                       Changes in version 0.19.1                        

  - Upgrade to ggplot2 4.0.0 compatibility.

                 Changes in version 0.19.0 (2025-07-16)                 

  - Add gf_resid() and gf_squaresid() functions for residual and squared
    residual plots that layer onto ggformula::gf_point() plots.

                 Changes in version 0.18.1 (2024-12-12)                 

  - Add alternate name Fingers$Gender to Fingers dataset to prevent
    awkward naming in exercises.

                 Changes in version 0.18.0 (2024-08-16)                 

  - Remove dependency on pak. pak was initially used to manage and parse
    dependencies, but itself depends on curl. curl is not available on
    all platforms (e.g. WASM), so we have removed the dependency on pak
    and opted for pure R where possible (or remotes which has a pure R
    fallback).
  - Add FoodQuality to TipExperiment dataset.
  - Various CI improvements: update for compatibility with more rhub
    platforms, don't run vdiffr tests on CI, allow tests to run in
    parallel.
  - Fix CRAN note by adding missing package anchors to link targets

                 Changes in version 0.17.0 (2024-05-26)

                       Changes in version 0.16.1

                       Changes in version 0.16.0                        

  - Make fivethirtyeight and Lock5withR required packages using the
    Remotes field (this is non-standard, but we aren't on CRAN anyway)
  - Update to ggplot 3.5.0, which required some small changes to the
    theme parameters

                 Changes in version 0.15.0 (2023-12-14)

                 Changes in version 0.14.1 (2023-10-27)                 

  - Reduce calls to pak::pkg_status() to improve startup time
  - Address issue where require(lib.loc = ...) was sometimes being
    passed NA
  - Appropriately skip actions that require the user when running in
    non-interactive mode (and add related tests)

                 Changes in version 0.14.0 (2023-10-12)                 

  - Remove deprecated gf_model_old() function

  - Add coursekata.quickstart option, which can reduce load times
    significantly.
  - Reduce expensive lookups when attaching packages, further reducing
    load times.
  - Re-introduce gf_model tests for density plots now that upstream is
    fixed.
  - Add test_fit() simple model stats to help teachers evaluate student
    models.

                       Changes in version 0.12.0                        

  - Remove sse(), ssm(), ssr(), SSE(), SSM(), SSR() functions: they

    mask others)

    This has been fixed.

                        Changes in version 0.9.3
