1. Raise PHP and Joomla Version Requirement
- Minimum PHP version now is PHP 7.4.0
- Minimum Joomla version requirement is now 4.4.0
2. Code Clean Up
In earlier version of Payment Form, we have to maintain old code to support Joomla 3. From this version, we drop support for Joomla 3, so we spent time to clean up code to use latest Joomla API, remove the code which is needed to have the extension works well with Joomla 3.
Also, support for Twitter Bootstrap 2 and Twitter Bootstrap 3 was removed because on Joomla 4 and Joomla 5, most customers are using Twitter Bootstrap 5 and UIKIT 3 (from Yootheme)
3. Convert Payment Form Plugins To New Structure
Joomla 4 introduce new plugin structure which make it faster for plugins to run. As we dropped support for Joomla3, we could convert all plugins in the extension to use new structure, result in cleaner code and performance improvement.
