OpenTelemetry implementations are currently in beta status. This page tracks the overall release milestones as we move towards full releases for each language SIG. You can find more details about the milestones at this link.
Summary
Our current goal is to provide a generally available, production quality release by the second half of 2020. Currently, we are in the beta stage. What follows is a brief explanation of what we expect to be available, when.
0.2
This release included a functional tracing implementation. While the API may change, you should be able to use these releases to begin exploring and understanding the API and the SDK, and the changes that have been made from OpenTracing/OpenCensus. This release also included support for distributed context using the W3C TraceContext specification.
0.3 (first beta release)
v0.3 is expected to contain a functional metrics implementation. Again, you may see changes to the API and the SDK after this point, but it’s anticipated that these releases will allow you to explore and understand the changes that have been made from OpenCensus. In addition, this release is anticipated to include improvements to OpenTelemetry Context, various semantic conventions around trace and metric metadata, and a finalized OpenTelemetry protocol.
We are planning to take a wave of OpenTelemetry components to beta on or after March 16th 2020. These components include the Java, JavaScript, Python, Go, and .Net APIs and SDKs, along with the OpenTelemetry Collector, though more will be added if they’re able to meet their milestones in time.
We’ve set the following requirements for components to reach beta:
- All spec version <= 0.3 features must be implemented. For APIs and SDKs this includes all 0.3 features for traces, metrics, context propagation, and resource metadata. For the Collector this includes the OpenTelemetry proto format
- Smaller changes are already scheduled for the v0.4 and v0.5 versions of the spec, but they may be implemented during the beta. Presumably, beta feedback will create further changes
- All APIs will attempt to be final, with the goal of not introducing any breaking changes between beta and GA RC. If breaking changes must be introduced between beta and GA RC, they will be small
- Components must support the OpenTelemetry-native exporter. Components should support exporters for Jaeger, Prometheus, and Zipkin, though some of these might be added soon after the component enters beta. The Collector must also include receivers for these formats
- APIs must include at least one HTTP and gRPC integration, though these are packaged separately. APIs should include at least one SQL integration, and can include a web framework integration (this is a stretch goal)
<1.0 (additional beta releases)
These releases are expected to contain further improvements to the tracing and metrics API and SDK in response to feedback gathered during the prior alpha and beta releases. Additionally, we expect that the OpenTelemetry protocol will be fully implemented and languages will include an exporter to the OpenTelemetry Collector. At the end of these beta releases, we anticipate all APIs will be unlikely to change.
RC and GA
We anticipate that once the beta phase is complete, we’ll enter into a period of final stabilization work around the API, SDK, and other components. This includes benchmarking, profiling, interoperability testing suites, and other work to ensure that the final release is performant and of a high quality. This work is anticipated to complete by the second half of 2020.

Release v0.16.0
### Added - Add the `ReadOnlySpan` and `ReadWriteSpan` interfaces to provide better control for accessing span data. (#1360) - `NewGRPCDriver` function returns a `ProtocolDriver` that maintains a single gRPC connection to the collector. (#1369) - Added documentation about the project's versioning policy. (#1388) - Added `NewSplitDriver` for OTLP exporter that allows sending traces and metrics to different endpoints. (#1418) - Added codeql worfklow to GitHub Actions (#1428) - Added Gosec workflow to GitHub Actions (#1429) - Add new HTTP driver for OTLP exporter in `exporters/otlp/otlphttp`. Currently it only supports the binary protobuf payloads. (#1420) ### Changed - Rename `internal/testing` to `internal/internaltest`. (#1449) - Rename `export.SpanData` to `export.SpanSnapshot` and use it only for exporting spans. (#1360) - Store the parent's full `SpanContext` rather than just its span ID in the `span` struct. (#1360) - Improve span duration accuracy. (#1360) - Migrated CI/CD from CircleCI to GitHub Actions (#1382) - Remove duplicate checkout from GitHub Actions workflow (#1407) - Metric `array` aggregator renamed `exact` to match its `aggregation.Kind` (#1412) - Metric `exact` aggregator includes per-point timestamps (#1412) - Metric stdout exporter uses MinMaxSumCount aggregator for ValueRecorder instruments (#1412) - `NewExporter` from `exporters/otlp` now takes a `ProtocolDriver` as a parameter. (#1369) - Many OTLP Exporter options became gRPC ProtocolDriver options. (#1369) - Unify endpoint API that related to OTel exporter. (#1401) - Optimize metric histogram aggregator to re-use its slice of buckets. (#1435) - Metric aggregator Count() and histogram Bucket.Counts are consistently `uint64`. (1430) - `SamplingResult` now passed a `Tracestate` from the parent `SpanContext` (#1432) - Moved gRPC driver for OTLP exporter to `exporters/otlp/otlpgrpc`. (#1420) - The `TraceContext` propagator now correctly propagates `TraceState` through the `SpanContext`. (#1447) - Metric Push and Pull Controller components are combined into a single "basic" Controller: - `WithExporter()` and `Start()` to configure Push behavior - `Start()` is optional; use `Collect()` and `ForEach()` for Pull behavior - `Start()` and `Stop()` accept Context. (#1378) ### Removed - Remove `errUninitializedSpan` as its only usage is now obsolete. (#1360) - Remove Metric export functionality related to quantiles and summary data points: this is not specified (#1412) - Remove DDSketch metric aggregator; our intention is to re-introduce this as an option of the histogram aggregator after [new OTLP histogram data types](https://github.com/open-telemetry/opentelemetry-proto/pull/226) are released (#1412) ### Fixed - `BatchSpanProcessor.Shutdown()` will now shutdown underlying `export.SpanExporter`.
