KeePass Edition Comparison

KeePass currently is available in two different editions: 1.x and 2.x. They are fundamentally different (2.x is not based on 1.x). They mainly differ in portability and functionality:

• KeePass 1.x: Runs on all Windows systems with GDI+ (already included in Windows XP and higher). Does not need to be installed; is portable. Fewer features than 2.x.
• KeePass 2.x: Runs on all Windows systems with Microsoft .NET Framework 2.0 or higher (already included in Windows Vista and higher) and other operating systems (Linux, Mac OS X, etc.) with Mono. Does not need to be installed; is portable.
