Users now have the option to lock documents in order to protect the associated document file from being updated by another user. A document may only be unlocked by the user who locked it; although a method to override the lock can be made available to a subset of users as desired.
A historical record of all uploaded files for documents is also now available. The new Upload History tab for Documents allows the user to interact with a list of files previously associated with the document record. This version history also includes a snapshot of other important document attributes of the record at the time the file was updated.
