New Features

Support $lookup in CSFLE/QE (RUBY-3611 | PR)

You can now use $lookup in aggregation pipelines that reference CSFLE- and QE-enabled collections.

Allow keyAltName in encrypted fields map (RUBY-3773 | PR)

When defining the encrypted fields for a collection (for use with Queryable Encryption), you may now specify the key via the keyAltName field, instead of by directly referencing a keyId.

Deprecate legacy retry tuning options (RUBY-3703 | PR)

The following options are deprecated when set on a Mongo::Client:

  • :max_read_retries
  • :read_retry_interval
  • :max_write_retries

These relate only to the legacy retry feature, which is itself deprecated and slated for removal. Modern
retryable reads and writes are enabled by default and ignore these options.

Deprecate server version 4.2 (RUBY-3811 | PR)

MongoDB server version 4.2 is EOL, and support for it will be removed from the driver in a future driver release. If you are using MongoDB server version 4.2, please upgrade to a newer version soon.
