0.17.1

• gen_image has been deprecated; use nano_banana.
• gemini_searchR has been deprecated. See this
• Added documentation for the gemini.R package.
• Updated hexsticker

0.17.0

• Added nano_banana for image generation.

0.16.0

• API key transmission has been updated for improved security and compatibility. Previously, the API key was sent as a URL query parameter (e.g., ?key=YOUR_API_KEY). Now, all functions send the API key using the HTTP header x-goog-api-key, following Google Gemini API best practices.

• This change enhances both security and future compatibility. Users can continue to set their API key using setAPI(“YOUR_API_KEY”). There is no change to the user-facing function interfaces. The old method of passing the API key as a URL parameter is no longer supported.
