New Features 新功能

• Support for hibernation on computers where the system partition is encrypted in Windows Vista/XP/2008/2003.支持休眠状态的电脑上如果系统分区进行加密，在Windows vista/xp/2008/2003 。
• Ability to mount a partition that is within the key scope of system encryption without pre-boot authentication such as a partition located on the encrypted system drive of another operating system that is not running in Windows Vista/XP/2008/2003.能力挂载分区是关键的范围，系统加密，没有开机前验证，如分区设于加密系统驱动器上的另一个操作系统是没有运行在Windows vista/xp/2008/2003 。 Feature useful for users who want to backup or repair a TrueCrypt encrypted operating system from another operating system.功能非常有用的用户谁不想备份或修复truecrypt加密作业系统从另一个操作系统。
• Command line options for creating new volumes in Linux and Mac OS X.命令行选项为创造新的卷在Linux和Mac OS X

Improvements 改善

• Increased speed of AES encryption and decryption in Windows.增加的速度， AES加密和解密在Windows 。
• Faster booting when the system partition is encrypted in Windows Vista/XP/2008/2003.更快的开机时的系统分区进行加密，在Windows vista/xp/2008/2003 。
• When the system partition/drive is encrypted, the TrueCrypt Boot Loader is now stored in a compressed form and is, therefore, smaller.当系统分区/驱动器加密， truecrypt开机载入现正存放在一个压缩的形式和，因此，规模较小的。 If a non-cascade encryption algorithm is used (ie, AES, Serpent, or Twofish), the TrueCrypt Boot Loader is now small enough so that a backup of the TrueCrypt Boot Loader can be (and is) stored in the first drive cylinder.如果一个非级联加密算法是用来（即原子发射光谱法，蛇，或twofish ） ， truecrypt启动加载器是现在小到足以使一个备份的truecrypt启动加载器，可（是）能储存在第一个驱动器缸。 Whenever the TrueCrypt Boot Loader is damaged, its backup copy is run automatically instead.每当truecrypt启动加载器损坏，其备份是自动运行。

  As a result of this improvement, the following problem will no longer occur: Certain inappropriately designed activation software (used for activation of some third-party software) writes data to the first drive cylinder, thus damaging the TrueCrypt Boot Loader.由于这方面的改善，以下的问题将不再发生：某些不适当地设计激活软件（用于激活一些第三方软件）将数据写入第一个驱动器气缸，从而损害了truecrypt启动加载器。 The affected users had to use the TrueCrypt Rescue Disk to repair the TrueCrypt Boot Loader.受影响的用户已使用truecrypt救援磁盘修复truecrypt启动加载器。 This will no longer be necessary after upgrading to this version of TrueCrypt (provided that the system partition/drive is encrypted using a non-cascade encryption algorithm, ie, AES, Serpent, or Twofish).这将不再需要后，升级到这个版本的truecrypt （只要系统分区/驱动器加密使用非级联加密算法，即原子发射光谱法，蛇，或twofish ） 。

  Note: If your system partition/drive is currently encrypted using a non-cascade encryption algorithm (ie, AES, Serpent, or Twofish), a backup copy of the TrueCrypt Boot Loader will be automatically stored in the first drive cylinder when you upgrade to this version of TrueCrypt.注意：如果您的系统分区/驱动器是目前加密使用非级联加密算法（即原子发射光谱法，蛇，或twofish ） ，备份的truecrypt启动加载器会自动储存在第一个驱动器缸当您升级到这个版本的truecrypt 。

• The minimum memory requirements for the TrueCrypt Boot Loader (AES) have been reduced from 42 KB to 27 KB (twenty-seven kilobytes) in Windows Vista/XP/2008/2003.最低内存要求为truecrypt启动加载器（ AES ）的已显着降低，从42 KB到27 KB （下27千字节）在Windows vista/xp/2008/2003 。 This allows users to encrypt system partitions/drives on computers where the BIOS reserves a large amount of memory (provided that the AES encryption algorithm is used).这使得用户加密系统分区/驱动器的电脑的BIOS储备了大量的记忆体（提供AES加密算法是使用） 。

Resolved Incompatibilities 解决不兼容问题

On some computers running Windows Vista/XP/2008/2003, when performing the system encryption pretest, Windows failed to display the log-on screen.在某些计算机上运行Windows vista/xp/2008/2003 ，当执行系统加密试验，在Windows无法显示登录屏幕上。 This will no longer occur.这将不再发生。

Bug Fixes 错误修正
