X.Org server 1.6新版本更新

The latest X.Org server, version 1.6, is available in Jaunty. For a little while, this will again cause increased instability for some users while the proprietary video drivers catch up.

字体大小优化设置

Font dot-per-inch settings are now optimized based on your monitor's capabilities, rather than defaulting to 96 dpi. You can further customize your dpi settings via System → Preferences → Appearance → Fonts → Details... 

新的通知及设置样式设计

Included in Jaunty is a simple menu which can be used to set preferences for notification icons, such as where they pop up on the taskbar. There is a possibility that Ubuntu 9.04 will get a whole new notification system, as shown in the Flash movie here:

更新的内核Linux kernel 2.6.28

Alpha 6 includes the 2.6.28-8.26 kernel based on 2.6.28.7. 

Ext4 文件系统支持

Alpha 6 supports the option of installing the new ext4 file system. ext3 will remain the default filesystem for Jaunty, and we will consider ext4 as the default for the next release based on user feedback.

Ext4 support in gparted has been provided by Curtis Gedak.
