    • Set author of the post depending on a condition. For example, you can change the author of the post if the post has a specific category.

16.6. v1.10.1 - 25 August 2020

  • Make it compatible with the major changes made in WordPress 5.5. WordPress 5.5 does not include jQuery Migrate, which lets deprecated jQuery functions be used for backward compatibility. This caused the plugin’s some JavaScript features to not work properly. This version removes the usage of any deprecated jQuery functions. Additionally, as instructed by WordPress’s official Test jQuery Updates plugin, the plugin has been thoroughly tested with all of the 4 specified combinations of jQuery, jQuery Migrate, and jQuery UI.
