🌱 A new release!
6.3.0 (2023-11-15)
The MongoDB Node.js team is pleased to announce version 6.3.0 of the
mongodb
package!Release Notes
New client option
serverMonitoringMode
added.For users that want to control the behaviour of the monitoring connection between each node in the topology, a new option,
serverMonitoringMode
, has been added. This defaults toauto
but can be forced into a specific mode by providing a value ofpoll
orstream
. A polling monitor periodically issues ahello
command to the node at an interval ofheartbeatFrequencyMS
. A streaming monitor sends an initialhello
and then will automatically get a response from the Node when a change in server configuration occurs or at a maximum time ofheartbeatFrequencyMS
. The value of that option defaults to 10000 milliseconds.This new option can be provided in the connection string or as an option to the
MongoClient
.GridFS fields deprecated
The GridFS
contentType
andaliases
options are deprecated. According to the GridFS spec, applications wishing to storecontentType
andaliases
should add a corresponding field to themetadata
document instead.Fill in title or leave empty for no highlight
Fix connection leak when serverApi is enabled
When enabling serverApi the driver's RTT mesurment logic (used to determine the closest node) still sent the legacy hello command "isMaster" causing the server to return an error. Unfortunately, the error handling logic did not correctly destroy the socket which would cause a leak.
Both sending the correct hello command and the error handling connection clean up logic are fixed in this change.
