100.16.0 Changelog

Released 2026-04-01

We are pleased to announce version 100.16.0 of the MongoDB Database Tools.

The highlight for this release is MongoDB Server 8.3 support, as well as support for new server features. There are a few important changes to note:

• When running against MongoDB 8.3, mongoexport no longer supports exporting collections in the system.buckets. namespace.

• When running against MongoDB 8.3 with authentication enabled, mongodump requires the performRawDataOperations permission in addition to find. The built-in backup role contains this permission.

Investigation:

• TOOLS-4039 - Explicitly replicate multikey writes in a multi-doc transaction

Build Failure:

• TOOLS-4108 - Fix missing document in capped collection during mongodump testing

• TOOLS-4141 - Fix failing QA tests on Windows for MongoDB 8.2

Bug:

• TOOLS-4145 - mongorestore failure when batch size exceeds maxMessageSizeBytes

• TOOLS-4154 - mongorestore is not handling empty partialFilterExpression option correctly

Task:

• TOOLS-4120 - Ignore "cu" type oplog entries for dump/restore

• TOOLS-4127 - Add pre-release 8.3 version to testing matrix

• TOOLS-4130 - Run passthrough tests with 8.1 and 8.2

• TOOLS-4134 - Add basic time series tests for import/export

• TOOLS-4136 - Add passthrough tests for 8.3

• TOOLS-4146 - Add support for rawData CRUD API to mongodump/mongorestore and mongoimport/mongoexport

• TOOLS-4147 - Remove workaround for rawData on admin database

• TOOLS-4150 - Ensure tools work with changes in SPM-4355

• TOOLS-4153 - Enable 8.3 in Linux package repos

• TOOLS-4158 - All tools should properly escape database and collection names in output
