الموضوعات المخطط لها

• A breaking change makes a correctly working consumer fail or misbehave without the consumer changing.
• Usually compatible: adding an optional response field, a new endpoint, a new optional request parameter.
• Usually breaking: removing or renaming a field, changing a type or unit, making an optional input required, tightening validation, changing status codes or error shapes.
• Changing meaning (cents to decimal euros) is breaking even when the type stays the same.
• Direction matters: producers break consumers; consumers break producers by requiring more than was promised.
