One of the best ways to keep up with Lightroom’s latest announcement is to read the Lightroom Journal. (Thanks to Tom Hogarty and the Lightroom team.)

I just purchased the new Canon 5D Mark III and was wondering when it will be compatible with LR4? Thank you!
You can download the Lightroom 4.1 Release Candidate from the Adobe Labs site today or wait until we make the 4.1 update official. But I don’t have a timeframe to give you on that date.
