Breaking Changes

●Issue #1

Azure CosmosDB spans no longer include http.status_code tags; they are replaced by the db.response.status_code metric. Users relying on http.status_code tag on cosmosdb.query spans from ddtrace v4.8.0 must update their queries to use the new metric.

Migration Steps

  1. 1
    If you rely on the `http.status_code` tag on Azure CosmosDB query spans, update your monitoring queries to use the `db.response.status_code` metric instead.

Release Summary
