[oXygen-sdk] [Ann] Oxygen XML Editor version 21.1 release

Hi everybody, We released a couple of days Oxygen XML Editor version 21.1 and the corresponding Author SDK. Our list of API improvements can be found here: https://www.oxygenxml.com/xml_editor/whats_new.html#21.1API As always we tried to keep Oxygen as backwards compatible as possible with plugins and we added no incompatible change in this release. Although it still comes bundled with Java 1.8 (which is still the recommended Java version to run Oxygen) Oxygen 21.1 was tested and should work also with Java 11 or 12 without any changes.
