The PHP team is happy to announce that version 1.10.1 of the MongoDB PHP library is now available.
Release Highlights
This release changes the server selection logic for Database::aggregate() and Collection::aggregate() when the pipeline contains $out or $merge . The 1.10.0 release added support for executing these pipelines on 5.0+ secondaries, but introduced a bug that could cause a server selection failure in a mixed version replica set. With this change, a secondary will only be eligible if all servers in the topology are 5.0+; otherwise, the library will fall back to selecting a primary server.
