-## Troubleshooting
+## Driver Extensions
 
-The MongoDB driver depends on several other packages. These are:
+The MongoDB driver can optionally be enhanced by the following feature packages:
 
-- [bson](https://github.com/mongodb/js-bson)
-- [bson-ext](https://github.com/mongodb-js/bson-ext)
-- [kerberos](https://github.com/mongodb-js/kerberos)
-- [mongodb-client-encryption](https://github.com/mongodb/libmongocrypt#readme)
+Maintained by MongoDB:
+
+- Zstd network compression - [@mongodb-js/zstd](https://github.com/mongodb-js/zstd)
+- MongoDB field level and queryable encryption - [mongodb-client-encryption](https://github.com/mongodb/libmongocrypt#readme)
+- GSSAPI / SSPI / Kerberos authentication - [kerberos](https://github.com/mongodb-js/kerberos)
+
+Some of these packages include native C++ extensions.
+Consult the [trouble shooting guide here](https://github.com/mongodb/node-mongodb-native/blob/HEAD/etc/notes/native-extensions.md) if you run into compilation issues.
+
+Third party:
+
+- Snappy network compression - [snappy](https://github.com/Brooooooklyn/snappy)
+- AWS authentication - [@aws-sdk/credential-providers](https://github.com/aws/aws-sdk-js-v3/tree/main/packages/credential-providers)
 
-Some of these packages include native C++ extensions. Consult the [trouble shooting guide here](https://github.com/mongodb/node-mongodb-native/blob/HEAD/etc/notes/native-extensions.md) if you run into issues.

 The `keepGoing` option was a legacy name for setting `ordered` to `false` for bulk inserts.
 It was only supported by the legacy `collection.insert()` method which is now removed as noted above.
 
+### `bson-ext` support removed
+
+The `bson-ext` package will no longer automatically import and supplant the `bson` dependency.

 ### `BulkWriteResult` no longer contains a publicly enumerable `result` property.
