Hey, if you read my journal and have LightRoom you definitely need to know about this. If you upgraded to LightRoom 1.4 get that sucker off your computer right away. Some bugs got through in the update that will mess up your RAW and JPG files and EXIF data. If you converted anything in LightRoom 1.4 to DNG god help you, you'll need to use another converter to correct the error LightRoom introduced (time consuming).
Here's a link to the write up on this-
http://blogs.adobe.com/lightroomjournal . In the comments section for the second post you can read all the problems this has caused. The update has been pulled from Adobe's site now. I hope this heads up helps before some one converts all their files to DNG. Please send this to other photography communities you belong to as it looks like this is going to cause many people major headaches.
Really damned annoying that they have not posted this at the head of their site. It is however up at photoshop news however.
