AndroidCentral is reporting that some of their users are experiencing a "silent updated" market. This update is mostly reported by Galaxy S device owners, so people like me that have a Fascinate should have this on our devices. The problem with this news is even AC themselves could not confirm because apparently their device does not have the new 2007 version but still have the older 1714 release. This update apparently gives you a simple and more assistive search feature, and a slightly improved UI for the market itself but the full changes were not specified.
If you have a fascinate or an Elcair device, check and see if you are experiencing some new improved market features.
