Released September 14, 2021

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.
  • db.setSecondaryOk(), mongo.setSecondaryOk(), and rs.secondaryOk() methods are reintroduced but deprecated. These methods alias to mongo.setReadPref().
  • When you enter multiline input into the shell, single-line // comments are now preserved as /* comments */ in the history entry.

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.

Full release notes available on JIRA.

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.


    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

  • Miscellaneous other improvements.

Released July 9, 2021

New features in this release:

  • All the static methods of the Node.js driver BSON classes are now available. Specifically, you can use ObjectId.createFromTime(unixTimestampSeconds) instead of the legacy shell’s ObjectId.fromDate(dateObj).
  • When connected to an Atlas deployment, the default mongosh prompt displays Atlas instead of Enterprise.

Released September 15, 2020

Released September 14, 2020

This release adds support for:

  • New cursor methods
  • Query planCache methods
  • Error helper 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.


    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.


    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.
