Ubuntu 7.10正式版终于出台了。我最关心的当然是其服务器版的新特性，瞧瞧吧：）

New Functionality

• Enhanced security – AppArmor provides significantly enhanced security which protects the server from intrusion. Common server applications such as Apache and Postfix are protected with default policies. Administrators can easily lock down programs and resources and add policies for their specific requirements.

• Virtualized kernel - A tailored kernel optimized for use in virtualized environments. This smaller and simpler kernel is particularly suited for virtual appliances. This new kernel includes many improvements for paravirtualization, one of which is VMI (Virtual Machine Interface), a new independent way for hypervisors to relate to the kernel.

• Tickless kernel - A new "tickless" idle mode resulting in reduced power consumption/heat emission - This feature results in significant energy and cost savings on machines running several virtualised instances.

• Messaging - Deployments of large mail servers benefit from significant improvements to Postfix's performance. The new stable release of Postfix takes advantage of the kernel's epoll functionality to reduce load and improve performance.

• Printing - Improved interoperability with CUPS now supporting automatic discovery and authentication for many more protocols, including LDAP with SSL, Kerberos, MacOSX Bonjour and Zeroconf.

• Programming - A new release of Python allows for a faster and more reliable interpreter. Additionally OpenMP is now supported in gcc 4.2, which gives shared-memory programmers a simple and flexible interface for developing parallel application.

Improved Compatibility

• LDAP authentication - Ubuntu Server is now fully supported as an LDAP authentication client. Additionally, a new profile based configuration utility (auth-client-config) makes setup of multiple servers easier than ever.

• File sharing - Enhanced Samba compatibility with Microsoft Windows clients, including Vista, that allows for better performances and off line login.

Enhanced Manageability

• Quick start profiles Three new quick start profiles have been added supporting Mail, Print and Database server set up. These profiles are in addition to the existing LAMP and DNS ones and significantly ease deployment, management and maintenance for common "edge of the network" functions.

• Landscape Management - Commercially supported users of Ubuntu Server can take full advantage of this web-based management tool for managing large deployments.

改天有空可以试试，看看之前碰到那些阻止我继续使用ubuntu的问题是否涛声依旧。
