DiffX: A Next-Gen Extensible Diff Format

Software developers are familiar with diff files, but existing formats like Unified Diff have limitations: lack of standardization, difficulty parsing metadata, and no support for binary patches. This article introduces DiffX, a new diff format that's fully backward compatible while adding structured metadata and extensibility. DiffX supports multiple commits, binary diffs, text encodings, and can be easily parsed and modified by modern tools, improving code review and patch management efficiency.
