We're very excited to announce the first alpha release of Swift OTel, based on the refined public API discussed in "[Swift OTel: Proposed revised API for 1.0 release](https://forums.swift.org/t/swift-otel-proposed-revised-api-for-1-0-release/80214)". Thanks again to the community for providing feedback 🏎 We just tagged [1.0.0-alpha.1](https://github.com/swift-otel/swift-otel/releases/tag/1.0.0-alpha.1) and would love for you to take it for a spin in your applications. ## πŸ†• What's new in Swift OTel 1.0? - **Complete public API overhaul:** We massively simplified and reduced our public API to provide a much friendlier bootstrapping. This makes it trivial to set up observability for your Swift applications. - **Logging support:** Logging is the latest signal added to Swift OTel, completing our support for the three pillars (Logging, Metrics, and Tracing). It's "one library to export them all"β„’. - **OTLP/HTTP+Protobuf and OTLP/HTTP+JSON exporters:** In addition to the gRPC-based exporter (which is now on 2.0), we added support for exporting via HTTP, sending either Protobuf or JSON encoded data. Some observability tools like Prometheus only support `http/protobuf` and Swift OTel now enables you to use them directly. - **Flexible configuration** : We expanded the supported configuration options to match the OpenTelemetry spec as close as possible, including support for mTLS. ## 🌱 Getting started Our updated documentation is available on the [Swift Package Index](https://swiftpackageindex.com/swift-otel/swift-otel/main/documentation/otel). We also expanded the [examples directory](https://github.com/swift-otel/swift-otel/tree/main/Examples) to highlight various Swift OTel set ups like using mTLS, exporting via different protocols, and disabling some of the signals. ## πŸ“‹ Call for Feedback We're looking forward to hearing how Swift OTel 1.0 is working for you! Please reply here directly or [open an issue on GitHub](https://github.com/swift-otel/swift-otel/issues/new). We're aiming to finalize the 1.0 release process within the next couple of months. ## πŸ… Shoutouts Let me end this post with a quick shoutout to everyone that helped this alpha come to live. Ginormous special shoutout to @beaumont who not only contributed Metrics support last year but also helped out tremendously with the new public API, examples, HTTP support, and countless more PRs. Also big thanks to @Honza_Dvorsky, @ktoso, and @Joannis_Orlandos for providing great input along the way ❀ Thank you, Moritz ---

Thank you to everyone who already gave our alpha 1 release a go and provided helpful feedback on GitHub πŸ™ ## Alpha 2 now available We just tagged [`1.0.0-alpha.2`](https://github.com/swift-otel/swift-otel/releases/tag/1.0.0-alpha.2) with a bunch of updates and would love for you to check it out to see if it improves your experience using Swift OTel. ### Release Highlights Here are some of this release’s highlights: #### Retry in OTLP/HTTP and OTLP/gRPC exporters Both OTLP/HTTP and OTLP/gRPC exporters are now more robust, retrying failed export attempts with exponential backoff. #### Access to ServiceContext's otelTraceID We now publicly expose the hex representation of a given ServiceContext's OTel trace ID. #### Support custom headers in OTLP/HTTP exporter We only supported adding custom headers when using the `OTLP/gRPC` exporter. Now this is enabled for the `OTLP/HTTP` exporter as well, allowing you to pass along headers such as API tokens. #### Environment overrides in makeXBackend APIs You're now able to override your OTel configuration via environment variable when using the lower-level `makeLoggingBackend`, `makeMetricsBackend`, `makeTracingBackend` APIs. Previously they were only applied to the high-level `OTel.bootstrap` API. #### Console log exporter You can now use the console log exporter instead of the default OTLP exporter. This comes in handy while developing your app, where you don't necessarily have a local observability backend up-and-running to view your logs. #### Performance improvements Alpha 2 contains a handful of performance improvements. For example, we now drop logs/spans when a batch processor's buffer overflows, emitting a diagnostic when it occurs. #### Improved graceful shutdown Swift OTel now shuts down more graceful, minimizing the amount of lost telemetry while shutting down. #### Improved diagnostics Diagnostic logs are now more detailed and should help pinpointing issues with Swift OTel more easily. #### New example projects Alpha 2 brings two new example projects: A hello-world server based on Vapor and a Hummingbird example exporting telemetry to Grafana LGTM. #### New Documentation Structure Our DocC documentation now includes documentation on the entire public API including all configuration options.
