Released September 20, 2022

Full release notes available on JIRA.

Released July 31, 2022

Fixes a potential data corruption bug in KeyVault.rewrapManyDataKey() when rotating encrypted data encryption keys backed by Azure or GCP key services.

In previous versions of mongosh, this bug occurs when an Azure-backed or GCP-backed data encryption key being rewrapped requires fetching an access token for decryption of the data encryption key.

As a result of this bug, all data encryption keys being rewrapped are replaced by new randomly generated material, destroying the original key material.

To mitigate potential data corruption, upgrade mongosh to v1.5.4 or higher before using KeyVault.rewrapManyDataKey() to rotate Azure-backed or GCP-backed data encryption keys. You should always create a backup of the key vault collection before key rotation.

Released July 29, 2022

New features in this release:

  • You can now run sh.status() when not connected to a mongos, for example when connected to a config server.

  • The Aggregation Pipeline parameter is now optional for db.collection.watch(), db.watch(), and Mongo.watch()

Bug Fixes in this Release:

  • mongosh now runs aggregations with $out or $merge immediately, and not lazily once the result of the aggregation is accessed.

  • Using the legacy NumberLong() method no longer truncates numbers outside of the 32-bit range.

Released August 12, 2021

New features in this release:

  • You can use config.set('maxTimeMS', <number>) to set a default maxTimeMS value for operations. maxTimeMS specifies a time limit in milliseconds within which the operation must complete.

    Note

    config settings persist across sessions.

  • On Windows, you can start mongosh by double-clicking on the .exe file. When you do, mongosh prompts you for a connection string to connect to your deployment.

  • The log files created by mongosh follow the format of the mongod, mongos, or mongocryptd. Meaning, the log files are newline-delimited JSON with the same set of fields used by the server.

Released August 4, 2021

New features in this release:

  • mongosh now uses version 4.1.0 of the Node.js driver, with full support for connections to load balancers and MongoDB Atlas serverless instances.

  • Miscellaneous other improvements.

Released July 9, 2021

This release adds support for:

  • New cursor methods

  • Query planCache methods

  • The following helper commands:

    • show users

    • show profile

    • show logs

    • show log[<name>]

This release includes an .rpm artifact which can be downloaded from the MongoDB Download Center.

Whenever a command's output includes { ok: 0 }, mongosh throws an exception and does not return the raw output from the server.

The legacy mongo shell error handling is not consistent between commands. mongosh standardizes the user-facing behavior for a more consistent experience.

  • MONGOSH-323: getUser() userId field is outputted as binary.

  • MONGOSH-337: Linux tarball is not gzipped.

  • MONGOSH-341: Wrong values with NumberLong for numbers > Number.MAX_SAFE_INTEGER. As a result of this fix, values passed to NumberLong and NumberDecimal must be strings.

    Important

    The fix for MONGOSH-341 is a breaking change when compared to behavior in the legacy mongo shell.

  • MONGOSH-346: Ctrl+C does not terminate the currently running command in the shell.

    Note

    Ctrl+C terminates the process in the shell, but does not terminate the process on the MongoDB server.

Released August 31, 2020

This release adds support for the following APIs:

  • Credentials are now properly redacted in logging and history.
