As you may have read already, Adobe has just released the update to Lightroom v.1.1 (You can download it here: Win, Mac). There are a number of discussions posted out there about what the new features are:And Scott Kelby has some news over on his blog about the new release as well as a free version 1.1 PDF update to his Lightroom Book called "My Lightroom 1.1 Update Kit" that should be uploaded tomorrow.
I downloaded the update last night before bed and then again this morning at work. I am about to finally get a chance to play with it and I'll do a P&P Workflow post about it later on today along with my first impressions of the improvements and new features.
