Apr 1, 2025April 2025 highlights for truera/trulens: Delivered core observability and stability improvements across TruLens. Key feature: OpenTelemetry integration for get_records_and_feedback, enabling end-to-end tracing with spans for data retrieval and feedback processing; added OTEL tracing helpers, updated app ID computation and attribute extraction, and comprehensive unit tests. Major reliability work: CI/CD and test stability hardening, including higher Poetry timeout, sequential test execution to reduce race conditions, HuggingFace pytest markers, longer model timeouts, and dependency maintenance to deflake E2E pipelines. Quality and assets: improved documentation naming consistency; notebook assets cleanup including restoration/removal of notebooks, refreshed test notebook links, and LangGraph assets tracked with Git LFS. These efforts jointly reduce release risk, improve observability, and boost developer productivity.
