MongoDB 3.2.0-rc1 has been released as the culmination of the 3.1.x development series and is now available for testing, following a bug hunt with $2000 in prizes and tickets to MongoDB World 2016 up for grabs. This release candidate fixes several issues including collection scan errors during concurrent move-update operations, replication code misunderstandings, support for replica set config servers with various storage engines, and performance improvements.
