Changes in version 0.1.1 (2025-08-23)                  

  - Models: restrict built-in presets to the OpenAI GPT-5 family (gpt-5,
    gpt-5-mini, gpt-5-nano); remove previous presets (gpt-4o,
    gpt-4o-mini, gpt-4.1, o1, o3-mini).
  - API compatibility: avoid 400 “unsupported_value” by omitting
    temperature for GPT-5 models (treated as simplified in this
    release).
  - UI/Settings: remove the temperature control and related logic; all
    conversations use the model’s default temperature. Documentation and
    tests updated accordingly.

                 Changes in version 0.1.0 (2025-04-24)                  

  - Initial Release to CRAN.
  - Provides an RStudio Gadget (run_llm_chat_app()) for interactive chat
    with OpenAI models (e.g., GPT-4o, GPT-4.1).
  - Supports multiple, tabbed conversations.
  - Allows uploading .R, .pdf, and .docx files as context for models
    supporting attachments.
  - Enables setting the model, temperature, and system message per
    conversation (before the first message).
  - Features asynchronous API calls to keep the R console responsive.
  - Includes helper functions for managing conversation history and
    settings (create_new_conversation, get_active_chat_history,
    set_conversation_model, etc.).
  - Requires an OPENAI_API_KEY environment variable for API access.
  - Added basic unit tests using testthat.
  - Added README.md and an introductory vignette
    (vignettes/PacketLLM-introduction.Rmd).
