Remember that clients should not be depending on the specific query
string data returned inside the query-continue or continue nodes. Clients should be treating the returned key-value pairs as opaque data to be returned to the server with the subsequent query.
Interested users may also wish to review the discussion thread from when a similar change was made last year.
To finish fixing bug 24782, Gerrit change 103589 changes the names and values of various items under the continue or query-continue node in the API response. Specifically,
* list=allimages will always use aicontinue, rather than sometimes using aistart. The formatting of the value for the modes that formerly used aistart will differ from that used by the modes that already used aicontinue.
