- N.744 Fixes concurrent modifications (example: a user modifies a team, another user modifies a person related to that same team). Still NOT fixed with the customer portal.
- N.849 Fixes links edition in the case some data are not allowed to the current user (organization silos) -TO BE TESTED
- #1145 Fixes the creation of duplicate links in one step (Server to NW Device)
- #1147 Fixes the update of duplicate links
