6.19.0 (2025-08-26)
The MongoDB Node.js team is pleased to announce version 6.19.0 of the
mongodbpackage!Release Notes
Experimental Support for Queryable Encryption Text Field Prefix, Suffix and Substring Queries
Important
Substring, prefix and suffix search are in preview and should be used for experimental workloads only. These features are unstable and their security is not guaranteed until released as Generally Available (GA). The GA version of these features may not be backwards compatible with the preview version.
When using Queryable Encryption with both automatic encryption and explicit encryption, text fields can now be queried using prefix, suffix and substring queries. This feature requires
mongodb-client-encryption@>=6.5.0.Allow a
secureContextfor Auto Encryption and Client Encryption TLS optionsThis can be provided in the
tlsOptionsoption both both objects.collection.findOne()andcollection.find()will no longer potentially leave open cursors on the serverThe
findOnecommand will now always set thelimitoption to1andsingleBatchtotrue. Thelimit,noCursorResponseandbatchSizeoptions have also been deprecated, and the command will guarantee no more cursors can be orphaned and nokillCursorscommand will be potentially executed.findwill now setlimittobatchSize + 1when both options were equal, to avoid leaving cursors open.Clients no longer send a ping on connect
When authentication is enabled, the
MongoClientwill no longer send apingcommand when connecting since it is unnecessary. Instead it will check a connection out of the pool to force the initial handshake, and check it back in.Features
