One of the good things about Adobe is that it has been diligent in releasing timely updates to Lightroom and Camera RAW in order to read the RAW files of the newest batch of cameras released, as well as provide new lens profiles and other fixes.
For those who may not know, Adobe typically releases a “Release Candidate” (RC) so early adopters can test it out and give feedback. It is essentially the finished version of the software update and for most users, the difference between the Release Candidate and the final version will be unnoticeable. The only caveat with the RC version is that there is an expiration date that coincide the release of the final version. In this case, the Lightroom 4.4 and Camera Raw 7.4 Release Candidates will expire on April 30th, 2013.
And of course, if you bought yourself a new Hasselblad Lunar (really!) or the other handful of new cameras supported, or just want to take advantage of the new fixes made in Lightroom and ACR, then you should download the new versions, as well.
