-== Upgrading from 2.x
-

-
-| `<mongo:mongo-client />`
-| Used to create a `com.mongodb.MongoClient`
-| Now exposes a `com.mongodb.client.MongoClient`
-
-| `<mongo:mongo-client replica-set="..." />`
-| Was a comma delimited list of replica set members (host/port)
-| Now defines the replica set name. +
-Use `<mongo:client-settings cluster-hosts="..." />` instead
-
-| `<mongo:db-factory writeConcern="..." />`
-| NONE, NORMAL, SAFE, FSYNC_SAFE, REPLICAS_SAFE, MAJORITY
-| W1, W2, W3, UNAKNOWLEDGED, AKNOWLEDGED, JOURNALED, MAJORITY
-|===
