We are happy to announce the 0.6.0 release.

Apart from the API improvements and dependency upgrades, there are several new documentation articles:

Note

The otel4s-core and otel4s-oteljava modules are binary compatible with 0.5.0 lineage.

Warning

The otel4s-sdk-exporter has several breaking changes and is binary incompatible with the 0.5.0 lineage.

New API

Span#addLink

You can add a link to another span by using addLink:

val span: Span[F] = ???
val link: SpanContext = ???
span.addLink(link)

OtlpSpanExporterAutoConfigure.customClient

You can supply a preconfigured http4s client to use with the OTLP span exporter. For example, you can provide a JDK11 HTTP client with configured proxy support:

import java.net.{InetSocketAddress, ProxySelector}
import java.net.http.HttpClient
import org.http4s.jdkhttpclient.JdkHttpClient

val jdkHttpClient = HttpClient
  .newBuilder()
  .proxy(ProxySelector.of(InetSocketAddress.createUnresolved("localhost", 3312)))
  .build()
  
OpenTelemetrySdk.autoConfigured[IO](
  _.addSpanExporterConfigurer(
    OtlpSpanExporterAutoConfigure.customClient[IO](JdkHttpClient(jdkHttpClient))
  )
).use { sdk =>
  ???
}

New stable semantic conventions

The semantic conventions have been updated to 1.25.0-alpha. There are several attributes are stable now:
