A.F....... [ZBX-20613] returned the ability to edit the dependencies of inherited triggers; improved validation upon unlinking templates with triggers that have dependencies; improved performance of trigger dependency functionality; prevented the ability to fully replace trigger dependencies of inherited triggers if the new dependency was added to parent trigger; supplemented validation of trigger dependencies on templates to prevent linkage dead-ends
