Definitions
The gradual decline in usefulness, reliability, or maintainability of software as dependencies change, assumptions age, and upkeep falls behind. It is often used interchangeably with code rot, but can describe broader operational or product decay as well.
In plain English: Software becoming harder to maintain or use as it ages and changes around it.
Example: "The admin panel suffered software rot once the browser support assumptions drifted out of date."
