Ctrl for iPad is regularly updated to support the latest version of iPadOS to take full advantage of new features the operating system has to offer.
Ctrl for iPad currently supports all iPads capable of running iOS 11.0.0 and above, however ON LX Limited recommends running a minimum of iOS 11.3.0
iOS 11.3.0 introduced an 'iPad Charge Management Feature' to improve iPad battery life over a prolonged period of time, perfect for installations where the iPad is unlikely to be unplugged. More details can be found on Apple's Release Document
Before updating iPadOS version it is recommended all Ctrl workspaces are exported as bundled workspaces to act as backups in the unlikely event of an iPadOS update failure.
Note: If any significant compatibility issues are discovered during the iPadOS beta testing stage, users will be notified not to update their iOS version until a fix is made
