+
+=== Fixed Issues
+
+* https://issues.couchbase.com/browse/NCBC-3340[NCBC-3340]: 
+When an op timed out, the socket connection was closed and then recreated.
+With a large number of unexpected timeouts, many sockets could be left in `TIME_WAIT`.
+Making `ChannelConnectionProcessor` reuse connections after timeout shoeld reduce the number of file descripters and local ports left open.
+* https://issues.couchbase.com/browse/NCBC-3356[NCBC-3356]: 
+Cluster level `query_context`, which is not supported by Server versions earlier than 7.0, has been removed for these versions.
+* https://issues.couchbase.com/browse/NCBC-3343[NCBC-3343]: 
+Fixed a bug where `SelectBucket` may not be called on the internal node used as the bootstrapping endpoint. 
+This resulted in a `BucketNotConnected` error for certain ops -- which will now no longer occur.
+
+=== New Features and Behavioral Changes
+
+* https://issues.couchbase.com/browse/NCBC-3309[NCBC-3309]: 
+Handled `query_context` changes by adding to every index manager request.
+* https://issues.couchbase.com/browse/NCBC-3348[NCBC-3348]: 
+When ConnectionString hosts are null, the SDK now throws an exception, with a more explicit error message.
+* https://issues.couchbase.com/browse/NCBC-3353[NCBC-3353]: 
+Removed build targets for out-of-support versions of .NET Framework.
