Backward compatibility
Backward compatibility is a property of a system, product, or technology that allows forinteroperability with an older legacy system, or with input designed for such a system, especially in telecommunications andcomputing. Backward compatibility is sometimes abbreviated to BC, or calleddownward compatibility.[1] Modifying a system in a way that does not allow backward compatibility is sometimes called breaking backward compatibility.[2] A complementary concept is forward compatibility, which is a design philosophy, usually based on open standards, that strives for methods that will continue to work with newer and future products. Design that is forward-compatible usually has a roadmap for compatibility with future standards and products.[3]

Compiler backward compatibility may refer to the ability of a compiler of a newer version of the language to accept programs or data that worked under the previous version.[7][page needed]
A data format is said to be backward compatible with its predecessor if every message or file that is valid under the old format is also valid, and retains its meaning, under the new.[8]
