Support for Drupal 7 is ending on 5 January 2025—it’s time to migrate to Drupal 10! Learn about the many benefits of Drupal 10 and find migration tools in our resource center.
I was just monitoring some additions being made to our project, and spotted
create mode 100644 sites/all/modules/contrib/lightbox2/js/prototype.js
create mode 100644 sites/all/modules/contrib/lightbox2/js/scriptaculous.js
which made me sad. I'm paranoid about library conflicts.
The project page says that a migration to jquery happened ages ago. Which made me happy again.
Scanning the code shows that these two libraries are not even called from code. lightbox2_add_files() has them commented out
Are they just source-control left-overs? Can they be safely removed from the project?
