Yesterday Adobe released a beta (unfinished testing) version of its next update to it's excellent photographic workflow management software, Lightroom.
The beta version of the software can be downloaded for free from the Adobe website over here and can be run alongside your existing install of Lightroom.
One of the more interesting developments in the new version is the addition of a new edit tool which allows the user to make changes to their photographs using a 'paintbrush' - much like in Photoshop.
Advanced users should take note that there is currently no infrastructure for using your existing plugins.
