what's new for iOS 18.4

In iOS 18.4, several new features and improvements have been introduced, particularly in the area of device management and app management. Here are some of the key updates:

Managed Apps: Managed apps have been officially taken out of beta. A new managed app framework is available for app developers, allowing organizations to securely deploy app configurations, including settings, passwords, certificates, and identities. This framework provides more control over app experiences and secure retrieval of API access tokens.
App Update Control: IT teams now have more control over app updates. The managed app configuration allows defining update behavior on a per-app basis, enabling enforcement or disabling of automatic updates. Apps can be pinned to specific versions, and real-time visibility into app installation progress and version information is provided.
Declarative Device Management: This feature is now available for deploying App Store apps, custom apps, and packages on macOS, with the ability to deploy them as required or optional.

These updates are part of Apple's ongoing efforts to enhance device management capabilities and provide more control and security for organizations using iOS devices. For more detailed information, you can refer to the session What’s new in Apple device management and identity.
