Now there is an option to assign operator to department/department group and at the same time exclude him from auto assignment workflow.
E.g You have operators who works only with VIP department, but when they don't have much to do they want to accept chats manually from lower level departments. With that option you can do that.
For update just follow standard update procedure For manual update it's update_278.sql
