Release of v3.2.5-alpha2
Remove all backward compatibility issues, so JCB will not need the [Backward Compatibility] plugin to run. Added new import powers for custom import of spreadsheets. Move the setDocument and _prepareDocument above the display in the site view and custom admin view. Update the trashhelper layout to work in Joomla 5. Add AllowDynamicProperties (Joomla 4+5) to view class to allow Custom Dynamic Get methods to work without issues.
