The great news is that current versions of all of our After Effects and Premiere Pro CC 2019-compatible plug-ins will continue to work in the new version. There is no need to update any of our tools.
Of course, if you want to make sure your Red Giant software is up-to-date, you can always get the latest installers on our Product Downloads page.
As always, if you have any issues, please reach out to our support team for help. We are here for you.
