Release Highlight
Fix retryability criteria for write concern errors on pre-4.4 sharded clusters
Previously, the driver would erroneously retry writes on pre-4.4 sharded clusters based on a nested code in the server response (error.result.writeConcernError.code). Per the common drivers specification, retryability should be based on the top-level code (error.code). With this fix, the driver avoids unnecessary retries.
