Microsoft has released an update to XNA Game Studio Express which adds new functionality, enhancements and performance improvements to the software. Officially dubbed the XNA Game Studio Express 1.0 Refresh, this release is an incremental update to the previously released XNA Game Studio Express 1.0.

The most significant new feature is the addition of XNA Packager, a utility which will allow users to build and share game binaries for both Windows and Xbox 360. Users can now easily package and share their games for Windows and Xbox 360 without having to share their project source code. The sharing of Xbox 360 games requires a subscription to the XNA Creators Club, which is available via Xbox LIVE Marketplace for $49 (U.S.) for a four-month subscription, or $99 (U.S.) for an annual subscription. The free update and a full feature list can be downloaded at here .
