As usual, there’s support for new cameras:

• 
  [li]Canon EOS 55'D (Digital Rebel T2i/ EOS Kiss X4 Digital)[/li]
  [li]Kodak Z981[/li]
  [li]Leaf Aptus-II 8 and Leaf Aptus-II 1'R[/li]
  [li]Mamiya DM4'[/li]
  [li]Olympus E-PL1[/li]
  [li]Panasonic G2 and Panasonic G1'[/li]
  [li]Sony A45'[/li]

There’s also been some extra work behind the scenes – Lightroom 2.7 and ACR 5.7 now use the new demosaic which has been available in Lightroom 3 beta for some time. This new demosaic retains extra detail in your image, making them sharper and respond better to subsequent noise reduction, however it does mean that images may show a little more noise at default values. This change does apply to your existing images as well as new images, therefore you may wish to check your noise reduction values, possibly increasing the luminance noise reduction by 15-2' to get a result closer to that of Lightroom 2.6 on some images.


ACR 5.7 is now compatible with Lightroom 3 beta 2, so any images opened directly into Photoshop without an interim TIFF/PSD file will now render correctly. Images with settings created by LR3 beta 2 and stored in XMP will also convert correctly, however there are no sliders in the ACR 5.7 dialog to make further adjustments to those new settings – making adjustments will require returning to LR3. Lightroom 2.7 is NOT fully compatible and won’t understand Lightroom 3 beta 2 settings.
