Released 2021 March 03 (build 44.24.18)
Contact person added for Library items
Librarians/All users: A slot for a Contact person has been added to the Info panels for all Library items. This makes it easier for users to know who best to contact about a Library item (especially helpful when an item has multiple Volume Librarians) and make the process of doing so much quicker as well.
A Contact person will automatically be assigned to all existing Library items. By default, it will be the person who last modified the item. If an item hasn't been modified, then it will be the person who added the item.
The Contact person can also be edited at any time by any of an item's Volume Librarians via the Info panel.
INCLUDES 57 other bug fixes and/or performance enhancements.
