  "message": "Refactored IsSet to examine keys\n\nThis patch refactors the IsSet function to examine the keys in order\nto see if a key is set instead of simply checking if a value is nil.\nThis change is necessary due to the fact that default values via\nflag bindings will result in the old logic always being true for\nthe IsSet function due to a type\u0027s default value such as 0 for an\ninteger or an empty string for a string. While a type\u0027s default\nvalue may be preferable when getting the value for a key, it\nresults in a false positive when determining if a key is actually\nset. This change enables users to detect whether a key is set by\nonly returning a flag\u0027s value if it has changed.\n",
