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 without any prerequisites. 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 installed. Does not need to be installed; is portable.
