Adobe Lightroom 2.3 is now available as a release candidate from the Adobe Labs website here:
ACR 5.3 is also available from:
The release candidate status it’s one step up from a beta version – it means that it’s been through some testing, but it would benefit from additional testing on a variety of different machines. It’s your opportunity to catch any bugs before it goes final, but it shouldn’t kill your machine.
New cameras: Nikon D3X, Olympus E-30.
It also fixes the Canon 5D MkII magenta shift on sRAW fileswhich was introduced with the Canon 1.0.7 firmware.
There’s a list of bug fixes in the readme file, but particularly notable are fixes (hopefully!!) for the memory issues that appeared in 2.2 for files with local adjustments.
There are also new languages supported: Chinese (Simplified), Chinese (Traditional), Dutch, Italian, Korean, Portuguese (Brazilian), Spanish & Swedish. There’s a little more work to do on the translations yet.
If you find any bugs, the Official Feature Request/Bug Report Form is just here.
