v0.1.1 — Apr 27, 2026

Latest New
  • TracelitClient.Metrics.Gauge(name, callback, ...) — observable gauge with a pull-based callback, no background timer needed
  • ResourceAttributes now supports Dictionary<string, string> and is applied to all signals (traces, metrics, logs)
  • Non-DI TracelitClient.Configure + TracelitClient.Start + TracelitClient.Shutdown path for console and worker apps
  • ./release.sh helper — bumps version, commits, tags, and triggers the NuGet publish workflow in one command
Improvements
  • AddTracelit() now registers ILogger → OTLP bridge automatically — no separate AddOpenTelemetryLogging() call needed
  • ErrorAlwaysOnSampler upgrades Drop decisions to RecordOnly (not RecordAndSample) so unsampled error spans don’t appear in trace waterfalls but are still exported to the logs table
  • dotnet.gc.* and dotnet.thread_pool.* metrics now exported via System.Diagnostics.Metrics runtime instrumentation (no reflection)
  • process.memory.rss poller uses IHostedService in DI apps so it respects graceful shutdown
Fixes
  • Fixed TracelitClient.Tracer.StartActiveSpan returning null when called before Start() — now returns a no-op span instead
  • Fixed Validate() throwing a NullReferenceException instead of a descriptive ArgumentException when ApiKey was not set
  • Fixed W3C traceparent propagation header not being injected on HttpClient requests when the activity had no parent
