You can now search and created Pinned Searches based on the created_at or updated_at attributes on assets. This allows you to create a Pinned Search for something like "Recently Updated" and make it easier for users of your Brandfolder to find the assets they need.
Some example search queries using these new attributes:
Find assets created in the last 30 days
Find assets updated in the last 3 months:
Find assets updated on April 24, 2015:
::updated_at:>2016-4-24 AND updated_at:<2016-4-26
Find assets created in 2015:
::created_at:>2014-12-31 AND created_at:<2016-1-1
