Apple is currently officially testing the betas of watchOS 10.4, iOS 17.4, iPadOS 17.4 and visionOS 1.1, among others. This way of testing new features through developers is effective because it allows Apple to debug the software and find new bugs. However, there may be other updates and new versions in development without needing to be in beta. Apparently, Apple is testing iOS 17.3.1 internally, an update that would arrive in the month of February for fix security bugs before the official launch of iOS 17.4 in March.

It is something that MacRumors has controlled for several years since they usually detect new versions by browsing their portal and, weeks later, they are officially launched. This is what happened a few months ago with iOS 17.2.1 or iOS 17.0.3.
