For many photographers, Lightroom has become a pretty important part of the photographic workflow. Now, the new version, Lightroom 5, is available to try before the final code is ready. There is no new RAW process with this version of Lightroom, so your images won't look noticeably different than they did in the previous version. One of the big jumps from version three to version four was the new process, so don't expect to see a change in your images right off the bat. They have added some nifty new tools, though.
