                     28: 
1.1.1.6 ! root       29: To install TrueCrypt, run the file 'TrueCrypt Setup.exe'. It is not
        !            30: necessary to restart the operating system after the installation
        !            31: finishes.
        !            32: 
        !            33: If you are upgrading from an older version of TrueCrypt, it should not
        !            34: be necessary to uninstall it first. However, if the installer reports
        !            35: any errors, we recommend uninstalling the older version first
        !            36: (Start Menu -> Settings -> Control Panel -> Add or Remove Programs).
        !            37: Note that uninstalling TrueCrypt never removes any TrueCrypt volumes.
        !            38: You will be able to mount your TrueCrypt volumes again after you
        !            39: reinstall TrueCrypt.

1.1       root       50: 
1.1.1.6 ! root       51: Bug fixes:
1.1       root       52: 
1.1.1.6 ! root       53: - Data corruption will not occur when data is written to a volume
        !            54:   encrypted with Twofish or Serpent while another TrueCrypt volume
        !            55:   is mounted (applies also to volumes encrypted using a cascade of
        !            56:   ciphers, out of which one is Twofish or Serpent).
        !            57: 
        !            58: - Other minor bug fixes
        !            59: 
        !            60: 
        !            61: WHAT IS NEW IN TRUECRYPT 3.0
        !            62: 
        !            63: New Features:
        !            64: 
        !            65: - Ability to create and mount a hidden TrueCrypt volume (file container 
        !            66:   or partition/device). This allows solving situations where the user is 
        !            67:   forced by an adversary to reveal the password and cannot refuse to do 
        !            68:   so (for example, when the adversary uses violence).
        !            69:   
        !            70:   The principle is that a TrueCrypt volume is created within another 
        !            71:   TrueCrypt volume (within the free space on the volume). Even when the 
        !            72:   outer volume is mounted, it is impossible to tell whether there is a 
        !            73:   hidden volume within it or not, because free space on any TrueCrypt 
        !            74:   volume is always filled with random data when the volume is created 
        !            75:   and no part of the hidden volume can be distinguished from random 
        !            76:   data.
        !            77:   
        !            78:   The password for the hidden volume must be different from the password 
        !            79:   for the outer volume. To the outer volume, (before creating the hidden 
        !            80:   volume within it) you should copy some sensitive-looking files that 
        !            81:   you do NOT really want to hide. These files will be there for anyone 
        !            82:   who would force you to hand over the password. You will reveal only 
        !            83:   the password for the outer volume, not for the hidden one. Files that 
        !            84:   are really sensitive will be stored on the hidden volume. 
        !            85:   
        !            86:   As it is very difficult or even impossible for an inexperienced user 
        !            87:   to set the size of the hidden volume such that the hidden volume does 
        !            88:   not overwrite any data on the outer volume, the Volume Creation Wizard 
        !            89:   automatically scans the cluster bitmap of the outer volume (before the 
        !            90:   hidden volume is created within it) and determines the maximum 
        !            91:   possible size of the hidden volume.
        !            92: 
        !            93:   More information on the hidden volume feature may be found at:
        !            94:   http://truecrypt.sourceforge.net/hiddenvolume.php
        !            95: 
        !            96: - Serpent encryption algorithm (256-bit key)
        !            97: 
        !            98: - Twofish encryption algorithm (256-bit key)
        !            99: 
        !           100: - Forced/"brutal" dismount (allows dismounting a volume containing files 
        !           101:   being used by the system or an application).
        !           102: 
        !           103: - Cascades of ciphers added (e.g., AES-Twofish-Serpent, AES-Blowfish, 
        !           104:   etc.) Each of the ciphers in a cascade uses its own encryption key 
        !           105:   (the keys are mutually independent).
        !           106: 
        !           107: - Ability to mount a TrueCrypt volume that is being used by the system 
        !           108:   or an application (shared access mode). 
        !           109: 
        !           110: - Ability to encrypt devices/partitions that are being used by the 
        !           111:   system or an application (shared access mode).
        !           112: 
        !           113: - The 'Select Device' dialog and the 'Auto-Mount Partitions' facility 
        !           114:   now support devices that do not contain any partitions.
        !           115: 
        !           116: - Encryption Algorithm Benchmark facility added to the Tools menu and to 
        !           117:   the Volume Creation Wizard.
        !           118: 
        !           119: - A warning is displayed if Caps Lock is on when creating a new volume 
        !           120:   or changing a password.
        !           121: 
        !           122: - When /l is omitted and /a is used, the first free drive letter is used 
        !           123:   (command line usage)
        !           124: 
        !           125: - New command line option: /force or /f enables forced ("brutal") 
        !           126:   dismount or mounting in shared mode (i.e., without exclusive access).
        !           127: 
        !           128: - Drive letters are now displayed in the 'Select Device' window
        !           129:  
        !           130: 
        !           131: Bug fixes:
        !           132: 
        !           133: - 'Blue screen' errors (system crashes) will not occur when dismounting 
        !           134:   a volume (remark: this bug was inherited from E4M).
        !           135:   
        !           136: - The 'Select Device' dialog will display also partitions being used by 
        !           137:   the system or an application.
        !           138: 
        !           139: - Users without administrator privileges can now create file containers 
        !           140:   under Windows Server 2003.
        !           141:   
        !           142: - If the size of a partition/device was not a multiple of 1024 bytes, 
        !           143:   its last sector (512 bytes) was not used for TrueCrypt volume (the 
        !           144:   volume was 512 bytes shorter than the partition/device). Remark: This 
        !           145:   bug was inherited from E4M, so it applies also to encrypted 
        !           146:   partitions/devices created by E4M.
        !           147:   
        !           148: - FAT volumes that are exactly 129 MB in size will not have zero size of 
        !           149:   free space (129-MB FAT volumes created by the previous versions had no 
        !           150:   free space available). 
        !           151:   
        !           152: - Other minor bug fixes
        !           153: 
        !           154: 
        !           155: Improvements:
        !           156: 
        !           157: - The timestamp of a container (date and time that the container was 
        !           158:   last accessed, and last modified) will not be updated when TrueCrypt 
        !           159:   accesses the container (i.e., after dismounting, attempting to mount, 
        !           160:   changing or attempting to change the password, or creating a hidden 
        !           161:   volume within it). 
        !           162:   
        !           163: - The TrueCrypt Service is no longer necessary and has been removed 
        !           164:   because its functions are now handled by the TrueCrypt driver.
        !           165:   
        !           166: - When 'Never save history' is checked, Windows is prevented from saving 
        !           167:   the file names of the last accessed file containers to the 'Recent 
        !           168:   Documents' and File Selector history. 
        !           169:   
        !           170: - Other minor improvements
