Retrieve the parts where availability has changed since the given timestamp.

Returns parts whose stock quantity has changed since the given `epochMilliseconds` timestamp — useful for keeping a local availability cache in sync without re-fetching the whole catalog. Pass `0`, or omit the parameter, to retrieve the full history. Results are capped at `recordCount` records per call (default 1,000); page through by re-calling with the timestamp of the last record you received.
