v0.16.0

The Sentry SDK team is happy to announce the immediate availability of Sentry Go SDK v0.16.0.
Due to ongoing work towards a stable API for v1.0.0, we sadly had to include two breaking changes in this release.

Breaking Changes

  • Add EnableTracing, a boolean option flag to enable performance monitoring (false by default).

    • If you're using TracesSampleRate or TracesSampler, this option is required to enable performance monitoring.

      sentry.Init(sentry.ClientOptions{
    EnableTracing: true,
    TracesSampleRate: 1.0,
})
  • Unify TracesSampler #498

    • TracesSampler was changed to a callback that must return a float64 between 0.0 and 1.0.

      For example, you can apply a sample rate of 1.0 (100%) to all /api transactions, and a sample rate of 0.5 (50%) to all other transactions.
      You can read more about this in our SDK docs.

      sentry.Init(sentry.ClientOptions{
    TracesSampler: sentry.TracesSampler(func(ctx sentry.SamplingContext) float64 {
         hub := sentry.GetHubFromContext(ctx.Span.Context())
         name := hub.Scope().Transaction()

         if strings.HasPrefix(name, "GET /api") {
             return 1.0
         }

         return 0.5
     }),
 }

Features

  • Send errors logged with Logrus to Sentry.
  • Add support for Dynamic Sampling #491
    • You can read more about Dynamic Sampling in our product docs.
  • Add detailed logging about the reason transactions are being dropped.
    • You can enable SDK logging via sentry.ClientOptions.Debug: true.

Bug Fixes

  • Do not clone the hub when calling StartTransaction #505
