This rvslots is not documented on API:Revisions and I don't find an email mentionning a compatibility problem on this subject.

I tried the API Sandbox, but the documentation for rvslots is cryptic for me : " Which revision slots to return data for, when slot-related properties are included in rvprops. If omitted, data from the main slot will be returned in a backwards-compatible format."

Any understandable explanation on this parameter and what value should I put, and what difference should I expect in the result ?

Oops, sorry. I will fix the docs and send an announcement tomorrow. This is for new functionality that is being added to MediaWiki incrementally as part of the Multi-Content Revisions project [1].

You can safely ignore the warning for now. You can specify rvslot=main, which will give you the same data, but in a slightly different format (and some deprecated options will trigger an error). At this point in time, no other slots are supported. Wikimedia Commons will soon have another slot available, for structured media information - see the Structured Data on Commons project [2] for details.
