Changes in version 0.2.0 (2026-07-10)                  

User-facing change

  - aigra_generate_items() now uses a data-frame-only interface. Users
    should load CSV or XLSX templates into R first and pass the
    resulting data frame through data = ....

  - Added aigra_read_template() to read AIGRA CSV and XLSX templates
    into R.

  - Added aigra_generate_from_data() as an alias for data-frame
    generation.

  - Added internal UTF-8 temporary CSV handling before calling the
    Python backend. This reduces common encoding problems for
    non-English item banks.

  - Added validation for required AIGRA tabular columns before backend
    execution.

Breaking change

  - The direct file_path argument has been removed from
    aigra_generate_items(). Use aigra_read_template() first, then call
    aigra_generate_items(data = ...).

                 Changes in version 0.1.2 (2026-06-05)                  

  - Added aigra_generate_items() as a simplified generation wrapper
    around aigra_generate_tabular_items().
  - Added direct API-key arguments: gemini.API, openai.API, groq.API,
    and anthropic.API.
  - Added aigra_set_api_keys() so provider keys can be supplied directly
    from R.
  - Added aigra_backend_help() to provide clearer guidance for
    configuring the external AIGRA_BACKEND folder.
  - Improved first-time user guidance for backend configuration and
    API-key handling.
  - Fixed documentation and namespace issues related to the new
    user-facing functions.
