刚刚收到Android Market 的电邮通知，表示在几日后Market 会有更新。
这次更新包括：
1. 程式的简介页上方会显示宣传图示 (promotional graphics)，这些宣传图示是由程式开发商为程式设定的。
2. 用户可根据内容评级筛选程式。即是早前介绍过的 All, Mature, Teen, Pre-teen 分类。若程式开发商未有为程式内容评级，就会被介定为 Mature。
3. 退款时限会缩短至 15 分钟。这个对用家很大很大影响，之前可以试用程式一排，遇到问题或不妥，可以在 24 小时内退款，现在是15分钟。15 分钟实在太短，点够时间试用呀！
4. 程式的APK档案由过往最大25MB 增至 50MB。即是，更复杂更大型的程式也可以在Market找到！
5. Market 会根据屏幕大小和GL texture 压缩程度进行过滤。即是不合符屏幕大小的程式，将不会显示。
6. Market 会将所有附有Wallpaper 和 Widget的程式，自动加至 “Dynamic” 分类。
Over the next several days, we’ll be updating Android Market on devices running Android 1.6 or higher. We’re writing to alert you to several changes being introduced with the update that may affect your applications:
* The details page for every app will now utilize and display the app’s “Promotional Graphic” assets at the top. If you haven’t done so already, we recommend uploading “Promotional Graphic” assets for your apps as soon as possible.
* Users will be able to filter applications by content rating. If you haven’t added a content rating for your published apps, you should do so immediately at the Publisher site by December 15 — applications or games without a rating will be treated as “Mature”.
* We will be reducing the purchase refund window to 15 minutes.
* We will be increasing the maximum size for .apk files to 50MB, from the current 25MB.
* Market will support filtering based on screen sizes and densities, as well as on GL texture compression formats. Filtering is based on
and elements in an app’s manifest. * If your app includes wallpapers or widgets, Market will automatically add them to new “dynamic” categories, based on their manifest files.
