Adobe has announced the availability of Release Candidate versions of Lightroom 4 and Camera Raw 7 on Adobe Labs. Version 4.2 and 7.2 respectively add support for several new cameras including the Canon EOS 650D / Rebel T4i, Canon EOS M, Panasonic DMC-G5, Nikon 1 J2 and Sony DSC-RX100. Both versions also add new lens profiles, including the Zeiss Distagon T 1.4/35 ZE and 2/25 ZE. Lastly, they fix numerous bugs with both programs, including issues with stacked images, publishing, the Defringe control and metadata writing.

Camera Raw 7.2 and Lightroom 4.2 Release Candidates are free to download from Adobe Labs. The Release Candidate status means that these updates are “well tested but would benefit from additional community testing before it is distributed automatically to all of our customers.”
