Whether you're using Anima on your browser or the Desktop application, you can see which version of the application you're currently using on the top left hand corner.
Anima will automatically update when a new version is available and you will receive notice in advance via in-app notifications and email. We advise having local IT support on hand to approve any required installs or address any IT permission.
For the Desktop application, you can easily check for software updates by navigating to Settings > Check for desktop app update.
