The MongoDB wire protocol opcodes used by the POCO MongoDB driver have been deprecated in MongoDB 5.0 (see [https://docs.mongodb.com/manual/reference/mongodb-wire-protocol/#std-label-wp-request-opcodes]). I stumbled across this when attempting to use Poco::MongoDB::InsertRequest to insert a document into a MongoDB 5.0 "time series" collection and it failed to work. These legacy opcodes have been replaced by the OP_MSG opcode introduced in MongoDB 3.6 with the associated wire transfer request and response changes.
Is the migration of the MongoDB driver from using legacy to modern protocols somewhere in the POCO roadmap?
