Each entry identifies the Python layer version and, when applicable, the shared exporter version it ships with. Nov 28, 2025 Python layer 29 · Lambda Telemetry Exporter 1.2.1 Improved Updated libraries used by the shared Lambda Telemetry Exporter. May 26, 2026 Python layer 32 Improved * Updated upstream OpenTelemetry Python instrumentation to `0.63.0`, including the AWS SDK, ASGI, Django, FastAPI, Flask, gRPC, Redis, SQLAlchemy, and database instrumentations. * Inspected and patched SDK libraries for FIPS environments. May 19, 2025 Python layer 26 Fixed Fixed an unhandled exception when `PutObject` is called with a non-ASCII payload. Apr 29, 2025 Python layer 25 · Lambda Telemetry Exporter 1.2.0 New * Added combined telemetry export, which sends logs, traces, and metrics in one request when `CX_COMBINED_TELEMETRY_ENABLED=true`. * Retries are now limited to eligible telemetry delivery errors. * Fixed broken SQS trigger span links. Apr 7, 2025 Python layer 24 · Lambda Telemetry Exporter 1.1.0 Improved * Added resource-attribute and `cx_metadata` controls, including `CX_LOGS_METADATA_INCLUDE_TRACE_REF`, `CX_LOGS_METADATA_INCLUDE_EXECUTION`, `CX_LOGS_METADATA_INCLUDE_INVOCATION_ID`, `CX_*RESOURCE_BUILT_IN_ATTRIBUTES`, and `CX_*RESOURCE_EXTRA_ATTRIBUTES`. * Added platform-log trimming controls: `CX_PLATFORM_LOGS_INCLUDE_REQUEST_ID` and `CX_PLATFORM_LOGS_HIDE_DEFAULT_VALUES`. * Supports splitting telemetry delivery between an OpenTelemetry URL and Firehose. Mar 25, 2025 Python layer 23 Improved Added Python 3.13 support and updated instrumentation packages to `0.52.0b`. Feb 5, 2025 Python layer 20 · Lambda Telemetry Exporter 1.0.1 Improved Made Firehose delivery errors more verbose. Jan 20, 2025 Python layer 19 · Lambda Telemetry Exporter 1.0.0 Fixed Ensured OTLP server sockets open before the extension registers with AWS. Dec 13, 2024 Python layer 18 · Lambda Telemetry Exporter 0.9.2 New Added `CX_PLATFORM_LOGS` to selectively disable platform event logs. Dec 5, 2024 Python layer 17 · Lambda Telemetry Exporter 0.9.1 Improved Added exporter warm-up spans. Nov 6, 2024 Python layer 16 · Lambda Telemetry Exporter 0.9.0 Fixed * Fixed the arm64 `GLIBC` issue and processing of spans received after `runtime_done`. * HTTP/2 is assumed when telemetry is sent to Coralogix or `CX_OTEL_URL`; re-enable ALPN with `CX_OTEL_APLN_ENABLED=t` when required. * Added the `ap-southeast-5` AWS Region. Oct 14, 2024 Python layer 15 · Lambda Telemetry Exporter 0.8.0 New * Added OOM detection for `Runtime.OutOfMemory` errors. * Added `CX_OTEL_LOGS_URL`, `CX_OTEL_TRACES_URL`, and `CX_OTEL_METRICS_URL` to route individual telemetry signals independently. Aug 2, 2024 Python layer 14 · Lambda Telemetry Exporter 0.7.0 New * Added early trigger and invocation spans for timeouts and function crashes. * Added telemetry metric reduction; set `CX_OTEL_METRICS_MODE=direct` to disable it. * Fixed OOM detection when memory use exceeds the configured limit. Jun 29, 2024 Python layer 13 · Lambda Telemetry Exporter 0.6.5 Fixed Fixed consumer spans not being recognized as the main function span. May 27, 2024 Python layer 12 · Lambda Telemetry Exporter 0.6.4 New Added `CX_SERVICE_NAME` to customize the default service name. Mar 29, 2024 Python layer 8 · Lambda Telemetry Exporter 0.6.3 Fixed Fixed `CX_TRACING_MODE=disabled` and `CX_TRACING_MODE=telemetry_api` forwarding OpenTelemetry traces. Only `CX_TRACING_MODE=otel` forwards them. Nov 30, 2023 Python layer 7 · Lambda Telemetry Exporter 0.6.2 Fixed Fixed truncation of logs containing multi-byte UTF-8 characters. Nov 27, 2023 Python layer 6 · Lambda Telemetry Exporter 0.6.1 Changed * Renamed `CX_PRIVATE_KEY` to `CX_API_KEY`; the previous name remains supported. * Fixed an incorrect missing-span warning. Oct 25, 2023 Python layer 5 · Lambda Telemetry Exporter 0.6.0 Improved * Added AWS Secrets Manager API key retrieval with `CX_SECRET`. * Redesigned telemetry delivery to improve shutdown and timeout reliability. Oct 5, 2023 Python layer 4 · Lambda Telemetry Exporter 0.5.2 Improved * Added `CX_EXCLUDED_SPAN_ATTRIBUTES` to filter sensitive span attributes. * Wrapper-and-exporter layers automatically select OpenTelemetry tracing mode when instrumentation is present. * Improved high-volume delivery and shutdown behavior. Sep 13, 2023 Python layer 3 · Lambda Telemetry Exporter 0.5.1 Improved Added `out_of_memory` to report logs, improved diagnostics, and propagated `telemetry.sdk.language`. Aug 11, 2023 Python layer 2 · Lambda Telemetry Exporter 0.5.0 New * Added experimental Firehose delivery and controls to selectively disable logs, traces, or metrics. * Improved failure handling, startup performance, OTLP support, debug logs, initialization-span creation, and telemetry reporting during fatal failures.
