Changes, Improvements, and Fixes

Improvement: Precondition Checks for Tunnel Start

OPERATORSERVICE PROVIDER

To improve usability and reduce failed connection attempts, the Start Tunnel button is now disabled when essential preconditions for the selected tunnel configuration are not met.

New Features

Remote Access without a Service Case context

Registering a new version of an application no longer triggers the deactivation of previous versions - previous versions can now be manually deactivated or otherwise remain in the published state. This makes it possible, for example, to publish different versions of the same application - with different machine compatibility settings - at the same time.
