== X.Org server 1.6 ==

The latest [[http://www.x.org|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.

== Font size optimization ==

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...}}}


== New style for notifications and notification preferences ==

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:

Alpha 5 includes the 2.6.28-8.26 [[http://kernel.org|kernel]] based on 2.6.28.7.

== Ext4 filesystem support ==

Alpha 5 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.

Alpha 5 adds Ext4 support to gparted (Curtis Gedak).

Introduction

The Ubuntu developers are moving quickly to bring you the absolute latest and greatest software the Open Source Community has to offer. The Jaunty Jackalope Alpha 5 is the fifth alpha release of Ubuntu 9.04, bringing with it a number of new features to improve daily computing.

Upgrading from Ubuntu 8.10
