Haroon Gondal migrated the Guess the Shape example notebook in the google-gemini/cookbook repository to use a new SDK, focusing on improving compatibility and maintainability. He updated the pip install command, revised import statements, and adapted the content generation call to align with the new SDK structure. Working primarily in Python and leveraging Jupyter Notebooks, Haroon consolidated all changes into a single migration commit, which streamlined future updates and reduced maintenance overhead. The work addressed the need for consistent SDK usage across the repository, ensuring that downstream projects could more easily adopt updates and maintain compatibility with evolving SDK standards.
