+What's New in 2.27
+------------------
+
+The 2.27 driver release includes the following new features:
+
+- Adds support for the ``$sample`` aggregation operator.
+
+- Implements the ``Equals()`` method for serializers in LINQ3.
+
+- Ensures that read and write concerns are not applied to Atlas Search Index
+  Helper commands to avoid errors.
+
+- Disallows the use of the comma character in ``authMechanismProperties``
+  connection string values when using the ``MONGODB-OIDC`` authentication
+  mechanism. 
+
+- Fixes a translation bug that caused an error during serialization involving
+  numbers of different sizes.
+
+- Adds support for Linux distributions that use the ``libdl.so.2`` library.
+
+For more information about this release, see the :github:`v2.27 release notes
+</mongodb/mongo-csharp-driver/releases/tag/v2.27.0>`.
