.NET Driver 2.16.0 Released

This is the general availability release for the 2.16.0 version of the driver.

The main new features in 2.16.0 include:

Support for MongoDB server version 6.0.0
[BETA] Support for Queryable Encryption
Support for creating collections with clustered indexes
Use count command for estimatedDocumentCount
LINQ3 bug fixes and improvements

Support for limit in $filter expressions
Support point-in-time pre-/post-images in change streams
Preemptively cancel in-progress operations when SDAM heartbeats timeout

EstimatedDocumentCount and Stable API

EstimatedDocumentCount is implemented using the count server command. Due to an oversight in versions 5.0.0-5.0.8 of MongoDB, the count command, which EstimatedDocumentCount uses in its implementation, was not included in v1 of the Stable API. If you are using the Stable API with EstimatedDocumentCount, you must upgrade to server version 5.0.9+ or set strict: false when configuring ServerApi to avoid encountering errors.

For more information about the Stable API see:
