New features:
- Full compatibility with 32-bit and 64-bit Windows Vista:
- Support for User Account Control (UAC).
- All .sys and .exe files of TrueCrypt are now digitally signed with the digital certificate of the TrueCrypt Foundation, which was issued by the certification authority GlobalSign.
- When moving the mouse on a single-CPU computer while reading or writing data to a TrueCrypt volume, the mouse pointer stopped moving for a second every few seconds. This will no longer occur. (Windows Vista issue)
- Other minor compatibility-related changes.
- TrueCrypt volume is automatically dismounted if its host device is inadvertently removed.
Important: You should always dismount the volume in TrueCrypt and then use the "Safely Remove Hardware" function (built in Windows) before you physically remove the host device (e.g. a USB flash drive).- Support for devices and file systems that use a sector size other than 512 bytes (e.g., new hard drives, USB flash drives, DVD-RAM, MP3 players, etc.)
- Support for devices with a GPT partition table (GUID partitions). (Windows Vista/2003/XP)
- After a partition is successfully encrypted, the drive letter assigned to it (if any) is automatically removed. (Windows)
- Volume name (label) is displayed in device/partition selector. (Windows)
- New hotkey: 'Wipe Cache'. (Windows)
- New command line switch '/q background' for launching the TrueCrypt Background Task. (Windows)
Improvements:
- Portions of the TrueCrypt device driver redesigned.
- Maximum allowed size of FAT32 volumes increased to 2 TB (note that NTFS volumes can be larger than 2 TB).
- Traveller Disk Setup improved. (Windows)
- Volumes hosted on read-only media will always be mounted in read-only mode. (Windows)
- Improved support for big-endian platforms.
- Other minor improvements (Windows and Linux)
Bug fixes:
- The built-in FAT format facility now functions correctly on big-endian platforms.
- Improved handling of partitions and devices during volume creation. (Windows)
- Improved handling of low-memory conditions. (Windows)
- Fixed bug that rarely caused system errors when dismounting all volumes. (Windows)
- Tray icon is recreated when Windows Explorer is restarted (e.g. after a system crash).
- Other minor bug fixes (Windows and Linux)
Security improvements:
- Improved security of set-euid mode of execution. Volume can be dismounted only by the user who mounted it or by an administrator (root). (Linux)
Removed features:
- It is no longer possible to create new volumes encrypted with 64-bit-block encryption algorithms (Blowfish, CAST-128, and Triple DES). 64-bit block ciphers are being phased out. It is still possible to mount such volumes using this version of TrueCrypt. However, it will not be possible to mount such volumes using TrueCrypt 5.0 and later versions (this applies also to volumes encrypted with AES-Blowfish and AES-Blowfish-Serpent, which have been in the process of being phased out since TrueCrypt 4.1). If you have such a volume, we recommend that you create a new TrueCrypt volume encrypted with a 128-bit-block encryption algorithm (e.g., AES, Serpent, Twofish, etc.) and that you move files from the old volume to the new one.
Improvements:
* Full support for custom screen DPI settings. (Windows, GUI)
* Other minor improvements. (Windows and Linux)
Bug fixes:
* Fixed bug that in some cases caused the 'Safely Remove Hardware' function to fail.
* In Windows Vista, it is now possible to read data from file-hosted TrueCrypt volumes located on UDF-formatted media mounted in read-only mode.
* All Volume Creation Wizard GUI elements are now correctly displayed on systems with custom DPI settings. (Windows, GUI)
* Other minor bug fixes. (Windows and Linux)
Security improvements:
* Linux: When running without administrator privileges, TrueCrypt automatically attempts to elevate its access rights (if necessary) using the sudo command. The Linux version of TrueCrypt no longer supports the set-euid root mode of execution. This change also fixes all discovered and undiscovered (if any) security issues related to the set-euid root mode of execution, including an issue affecting all previous Linux versions of TrueCrypt where a local non-administrator user could cause a denial of service or gain administrator privileges.
Miscellaneous:
* If dismount is forced on a TrueCrypt volume when TrueCrypt runs in traveller mode, the TrueCrypt driver will not be unloaded when TrueCrypt exits (it will be unloaded only when the system is restarted or shut down). This prevents various problems caused by a bug in Windows (for instance, it would be impossible to start TrueCrypt again as long as there are applications using the dismounted volume). (Windows)
Die wohl Interessanteste Änderung ist, das TC jetzt auch pre-boot encryption unterstützt - zumindest für Win 2k3/XP/Vista.
5.0a / February 12, 2008
Improvements:
The memory requirements for the TrueCrypt Boot Loader have been reduced by 18 KB (eighteen kilobytes). As a result of this improvement, the following problem will no longer occur on most of the affected computers: The memory requirements of the TrueCrypt Boot Loader 5.0 prevented users of some computers from encrypting system partitions/drives (when performing the system encryption pretest, the TrueCrypt Boot Loader displayed the following error message: Insufficient memory for encryption).
Bug fixes:
- On computers equipped with certain brands of audio cards, when performing the system encryption pretest or when the system partition/drive is encrypted, the sound card drivers failed to load. This will no longer occur. (Windows Vista/XP/2003)
- It is possible to access mounted TrueCrypt volumes over a network. (Windows)
- TrueCrypt Rescue Disks created by the previous version could not be booted on some computers. This will no longer occur. (Windows Vista/XP/2003)
- Note: If your TrueCrypt Rescue Disk created by TrueCrypt 5.0 cannot be booted on your computer, please upgrade to this version of TrueCrypt and then create a new TrueCrypt Rescue Disk (select 'System' > 'Create Rescue Disk').
- Many other minor bug fixes. (Windows, Mac OS X, and Linux)
Was macht überhaupt der TrueMounter?
Der TrueMounter ist ein Zusatzprogramm für Benutzer von TrueCrypt. Es
erweitert die Funktionalität von TrueCrypt um einiges. Die ursprüngliche
Hauptfunktion war das Mounten eines TrueCrypt-Laufwerks mit Hilfe eines
USB-Sticks. Doch dann sind noch einige Features hinzu gekommen, wie
z.B. der automatische Download eines Keyfiles von einem FTP Server oder
das Starten von Programmen nach dem Mounten.
Funktionen:
- automatisches Mounten von TrueCrypt Laufwerken mit Hilfe des USB-Sticks
(Beim Einstecken des Sticks wird gemountet, beim entfernen wird getrennt)
- Verwendung von Keyfiles oder Textdatei mit Passwort die sich auf dem Stick
befinden
- Mounten über FTP Server (mit SSL Unterstützung). Keyfile oder Textdatei muss
sich auf dem Server befinden
- Programme nach dem Mounten automatisch Starten und vor dem Trennen wieder
beenden
