-
-Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.

+== Upgrading from 2.x
+
+The 4.0 MongoDB Java Driver does no longer support certain features that have already been deprecated in one of the last minor versions.

+
+| `<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
