Changes in version 0.2.0                        

Chat integration

  - Require shinychat >= 0.5.0 and ellmer >= 0.4.1. Streaming,
    cancellation, and attachments are now delegated to
    shinychat::chat_server(), which relies on ellmer's stream
    controller. Conversation history stays disabled until it can restore
    the canvas and registry together. The package no longer imports
    {promises} directly (#17, #21).
  - Greetings now use the shinychat welcome message API and disappear
    after the first user message. They remain display only and are not
    sent to the model (#21).
  - Use shinychat::tool_result_display() for tool results and present
    tense titles for running tools. The mtcars example uses the input
    toolbar to keep its prompt buttons above the composer (#21).

Examples

  - Example and acceptance test apps now read their model and reasoning
    effort from the required SHINYGENUI_MODEL and SHINYGENUI_EFFORT
    environment variables instead of relying on defaults (#9).
  - The 01-mtcars-explorer example now offers prompt buttons above the
    chat composer. A click fills and focuses the composer without
    submitting (#10).

Documentation

  - The README now includes a recording of the mtcars explorer example
    (#11).
  - Code examples now consistently use the same model provider while
    continuing to support any ellmer provider (#8).

Branding

  - Add a hex sticker logo with a p5.brush watercolor polygon background
    (#14, #15, #24).

                 Changes in version 0.1.0 (2026-09-09)                  

New features

  - Use genui_component() to define a component and genui_catalog() to
    collect components into a catalog. Each component becomes an ellmer
    tool with validated arguments.
  - Use genui_canvas() and genui_server() to let the model add
    components to a running app. The included tools let it update or
    remove a component, clear the canvas, and inspect the current
    canvas.
  - Every call from the model passes through genui_dispatch() before it
    can change the canvas. If a call fails, the model receives the error
    and the Shiny session keeps running.
  - genui_components_bslib() provides a value box, Markdown card, data
    table, scatter plot, and histogram with a slider for the number of
    bins. genui_card_row() provides a container for arranging these
    components.
  - genui_trace() records each successful call. genui_replay() can
    rebuild the canvas from that record without an LLM.
