In our 7.6 release, we added the ability to create new types of libraries, including one for Responsibilities. This library is intended to replace the Responsibilities & Attributes library, which we no longer offer. But if you were using them previous to 7.6, we recommend recreating that content in a new Responsibilities library. Check out the Create one of the new types of libraries article to learn how to set one up.
While we encourage you to remove Responsibilities & Attributes libraries, they are still supported in the Libraries and Jobs modules. You can still view and manage Responsibilities & Attributes in Libraries. You can still add items from these libraries to a job. Jobs have been redesigned with an expandable section and icon for each type of library you've created in your site and assigned to Jobs, so we've added a matching section for Responsibilities & Attributes.
