We are pleased to announce that TrueCrypt 4.3 has been released. Among the new features are full compatibility with 32-bit and 64-bit Windows Vista, support for devices and file systems that use a sector size other than 512 bytes (such as new hard drives, USB flash drives, DVD-RAM, MP3 players, etc.), auto-dismount when a host device (e.g., a USB flash drive) is inadvertently removed, and many more. In addition to new features, there are many significant improvements. Some portions of the TrueCrypt device driver have been completely redesigned and several bugs have been fixed.
