Adobe's latest version of Lightroom, the photo management and editing tool, was released as beta back in January. Now it's been officially released as Lightroom 4, and brings with it a big drop in price; the full version now costs around £110 instead of the £250-of-so.
In terms of features, Lightroom 4 brings with it the option of assembling and ordering photo books directly from the software, location-based organization, baked-in Facebook and Flickr functionality, and new highlight and shadow editing features.
Existing Lightroom users can upgrade for £60-odd, while a new license costs around £110. [Adobe]
