3.5

• New multipleQueries() method at index level
• Fix cancellation of requests: in some edge cases, the completion handler could be called after cancellation
• Fix potential crash when cancelling requests (unsafe assertions were made)

The following changes are for the offline mode only:

• New offline fallback strategy. Warning: breaking change: preventive search no longer supported.
• Offline requests now also work for disjunctive faceting
• The searchMirror() method has been renamed to searchOffline(), for better consistency with the newly introduced searchOnline() method.
• Improve detection of non-existent indices
