Cytobank is a web application, and thus it can be updated and improved continuously without forcing you to update, reinstall, or reconfigure any software on your own computer. When you first log in to Cytobank after a new version of the platform has been released, you will see a popup box appear which outlines some of the new features in the latest version. The popup box will have multiple screens that you can view.
Once you close the box, it won't pop up again, but you can always get it back by navigating to the Help menu in the top right of your screen in Cytobank and clicking What's New.
You can also view release notes on the Cytobank website. If there is a video to accompany a release, it will be found there.
