The notes on this page highlight special changes that require separate mention beyond the release notes. This applies in particular when upgrading to a new Nuclos release requires certain additional preceding or subsequent measures that must be observed to avoid unwanted behavioral changes or side effects introduced by new features.
Generators (work steps) can be assigned permissions (NUCLOS-585)
An update of Nuclos therefore causes all generators to be initially hidden from all users. To make the generators visible and executable for users again, the assigned user groups must first be permitted for the generators. A user with the "Superuser" flag (e.g. the user "nuclos") always sees all work steps.
Record shares must be explicitly assigned to user groups (NUCLOS-595)
In earlier releases all record shares were automatically effective for all users, which quickly made the configuration of record-share data sources complex when different restrictions had to be made for different user groups. So that existing record-share data sources remain effective after an update of Nuclos, they must first be explicitly assigned to the user groups. For users with the "Superuser" flag (e.g. the user "nuclos") no record shares apply at all
