• New Feature: The software can now process both plain text and URLs as user input. If a URL is entered, the software will automatically extract the text from the webpage for processing.
• Improvement: Enhanced user feedback with a new message that informs users when an API call is being made.
• Refactor: Removed dependency on the networkx library, simplifying the codebase and reducing the software's footprint. This change does not affect the software's functionality.

"In the land of code, where the shadows lie,

We removed a package, with a satisfied sigh.

Now URLs we handle, with a keen eye,

Making our code, as light as a butterfly. 🦋"
