This release fixes fixes a critical security problem that allowed any user that can create content with a file field to delete other files in the Drupal installation.
This version of FileField marks the complete stabilization of FileField APIs, fixes a critical bug concerning the display of FileFields within views, another critical bug regarding CCK not storing data properly, and several other smaller bugs.
Important upgrade note: The "FileField Token" module has been merged back into FileField so that it is no longer a separate module. When upgrading, delete the filefield_token directory entirely. All the functionality of filefield_token is now included in filefield.token.inc.
