ChangeSet Spec
The ChangeSet definition can be found here; it consists of a set of Change objects. Each Change contains:

an op (operation),
a path which conforms to jsonpath syntax,
an optional value parameter, used in certain op types
an optional index parameter, used in certain op types

Changes are applied in the order they are received.
Operation Types
The following operations are supported:
Delete: "del"
Deletes all json nodes specified in the change path
Init: "init"
For all json nodes specified in the change path, if that node doesn't exist, its value is initialized to the change value. Otherwise, ignores the existing node.
Primarily used to ensure an array exists in the object tree before invoking Array Insert commands.
Upsert: "ups"
For all json nodes specified in the change path, creates or replaces that node, setting the value to the change value
Replace: "rpl"
For all json nodes specified in the change path, replaces that node, setting the value to the change value
Array Insert: "arr_ins"
For all json nodes specified in the change path, which must be of type array, insert the change value at the provided index.
If index is null, appends to the end of the array.
