Adobe released a free downloadable update to Lightroom 2 (bringing it to version 2.2), that adds support for some recently released cameras (including the Canon 5D Mark II, , a number of Panasonic cameras, and the Canon G10), along with some bug fixes (for a list of the bug fixes, visit Lightroom Product Manager Tom Hogarty’s blog by clicking here).
Also, (and this is big), this update includes the final versions of the Camera Profiles which will now be available in the Calibration panel (those of you who attended my Lightroom 2 Live Tour know about the Beta versions of these).
To get the free update, go under Lightroom’ 2’s Help menu and choose “Check for Updates.”
