Viewfinder 1.5.4 has been released. This new version is an emergency software update for Viewfinder. Today, a Flickr API authentication problem was reported to us by a customer. We were quickly able to determine that Viewfinder’s ‘API key’ had indeed been invalidated.
To fix this, 1.5.4 uses a new API key. What this means is that Viewfinder 1.5-1.5.3 will no longer be able to search for and download photos.
Viewfinder 1.5.4 is a free upgrade for all customers and is available through our normal software update channels. Customers are encouraged to update immediately. 1.5.4 runs on OS X Lion 10.7.3 and later, including OS X Mountain Lion, OS X Mavericks, OS X Yosemite, and OS X El Capitan.
