Adobe has revoked Lightroom 1.4 and Camera Raw 4.4 upgrades from the site due to an error in EXIF timestamp information being changed by the application. Adobe is recommending that those users who upgraded to revert back to Lightroom 1.3.1 and Camera Raw 4.3.1. What a mess, and crazy that they are actually changing original raw EXIF timestamps. Looks like either Adobe employees are slacking off or the competition from Apple is getting to them!
