What’s New in Lenses 5.0
- Wizard - First time installation without any helm / docker / api / cli / provisioning configuration will trigger Lenses Wizard. Lenses Wizard is an easy tool that will help user with Kafka and License configuration in a browser. After finishing Wizard, Lenses will start as usual.
- Core connections management - user can manage core connections (Kafka, Schema Registry, Kerberos, Kafka Connect, Zookeeper) in a real time. It means that now it is possible to add / test / update and delete core connection in much more friendly way without Lenses restart.
- License management - Lenses does not expect to find a license in a file. In case of migration Lenses will find license in the database (no additional action required). In case of new installation there is few other ways of providing license (check this ). License can be updated in the runtime (Admin -> License), without Lenses restart.
