Starting with release 2.0, VuFind was built on Zend Framework. During the development of VuFind 7.0, Zend Framework rebranded as Laminas, changing many class and package names but maintaining the same functionality.

Here are some helpful resources related to Laminas:

• Laminas Documentation - The official framework documentation.
• Zend Webinars - Many of these online videos deal with Laminas or Zend Framework issues.
• Using Zend Framework 3 (book) - This free book provides an introduction to Zend Framework 3, the precursor to Laminas. While the name has changed, the concepts remain the same.
