Adobe Labs just announced that the Lightroom 5.3 Release Candidate is out. The biggest thing you’ll find in this “dot” release is support for some new cameras (especially Sony’s A7’s and the new Nikon cameras). There’s a few bug fixes too, but none were anything that I ran into. I personally don’t usually install release candidate versions of the software, but if you’ve got one of those new cameras and want Lightroom support it’s worth it. Here’s the link if you want to check it out.
