Hello, We recently released version 22.1 of Oxygen XML Editor (and the corresponding SDK): https://www.oxygenxml.com/xml_editor/whats_new.html The list of newly added APIs is available here: https://www.oxygenxml.com/xml_editor/whats_new.html#22.1API As always, we kept Oxygen 22.1 backwards compatible with older and deprecated APIs so frameworks and plugins developed for older Oxygen versions should also work with the new version. Radu Coravu put together a blog post with an overview on the available Oxygen sample frameworks, plugins and add-ons: https://blog.oxygenxml.com/topics/all_about_oxygen_add_ons.html We hope you will enjoy our new release and we are looking forward for your feedback about how it works with your customizations. Best regards, Alin Alin Belu Oxygen XML Editor
