Adobe has released a wave of updates for its professional photography applications:
Adobe Photoshop CS5 12.0.2 (no release notes link, see download/updates link below)
Adobe Camera Raw 6.3 (click for release notes in PDF)
Adobe Photoshop Lightroom 3.3 (click for release notes in PDF)
As usual, you can read the release notes and download the installers from
To update Photoshop and Camera Raw directly, start Photoshop and choose Help > Updates.
To update Lightroom directly, start Lightroom and choose Help > Updates.
I may pull out some highlights from the release notes here later when I have more time, but for now you can refer to the links above.
