3.9.4

✨ Enhancements

• F::move() now detects if the source and target are on different filesystems; it then copies the file and deletes the source on success instead of atomically moving the file #5124
• Removed noopener  where it's already implied by noreferrer #5138
• Inherit when for field groups (thanks @youngcut) #5143

fields:
  showit:
    type: toggle
  myGroup:
    type: group
    when:
      showit: true
    fields:
      myField1:
        type: text
      myField2:
        type: text

• Introduced new YAML handler that can be activated by setting the config option yaml.handler to 'symfony'. We plan to switch over to the Symfony handler in the next major releases. For now, 'spyc' remains the default.

<?php 

// File: /site/config/config.php
return [
  'yaml.handler' => 'symfony'
];
