Hi, I try to write mechanism of fetching new data using your API. And I am confused, because API response in recent changes endpoint includes "rccontinue" like this: "20181222184231|119590". What is it? I mean this "|" and second value.

It's meant to be included in the followup request, to continue the list of changes from where you have left off. See https://www.mediawiki.org/wiki/API:Query#Continuing_queries

The value is meant to be opaque to the client. It's the combination of rc_timestamp and rc_id.
