Over the next two weeks Google will be rolling out a major update to the android market client. The changes will greatly improver the user experience as well as the browse-to-purchase experience. It will also be possible to develop richer games with the increase of the max size of .apk files to 50MB.

The Android Market engineering team has been hard at work on improving the Android Market experience for users and developers. Today, I’m pleased to announce a significant update to the Android Market client. Over the next two weeks, we’ll be rolling out a new Android Market client to all devices running Android 1.6 or higher.

This new Market client introduces important features that improve merchandising of applications, streamline the browse-to-purchase experience, and make it easier for developers to distribute their applications.

With a focus on improving discoverability and merchandising, we’ve introduced a new carousel on the home and category screens. Users can quickly flip through the carousel to view promoted applications and immediately go to the download page for the application they want. Developers have been very active in creating great Widgets and Live Wallpapers. To make it easier for users to find their favorites, we’re introducing two new categories for Widgets and Live Wallpapers. Applications that include Widgets and Wallpapers will be automatically added to those new categories. We’ll also be adding more categories for popular applications and games in the weeks ahead. In addition, the app details page now includes Related content, which makes it easier for users to quickly find apps of similar interest.
