Breaking Changes 🛠

• Replace the event-based transports with envelope-based ones. Custom transports need to implement the new Transport interface. See the transport section of the migration guide for details. by @giortzisg in #1427
  • Custom transports need to implement SendEnvelope(ctx, envelope) in place of SendEvent(event), and FlushWithContext(ctx) in place of Flush(timeout). The envelope types live in the new public protocol package.
  • The transport Timeout now applies to every request, including when a custom HTTPClient is set.
  • ClientOptions.DisableTelemetryBuffer is removed. The telemetry buffer is always used.
  • Transport BufferSize now counts envelopes instead of events, and defaults to 1000 instead of 30.

  // Before
  func (t *customTransport) SendEvent(event *sentry.Event) {}
  func (t *customTransport) Flush(timeout time.Duration) bool { return true }
  
  // After
  func (t *customTransport) SendEnvelope(ctx context.Context, envelope *protocol.Envelope) error { return nil }
  func (t *customTransport) FlushWithContext(ctx context.Context) bool { return true }

• Remove the Hub API. Scopes and clients are now carried on context.Context, so users need to pass the request or job context to Sentry functions instead of using a hub. See the migration guide for every replacement. by @giortzisg in #1407
  • CaptureException, CaptureMessage, CaptureEvent, CaptureCheckIn, AddBreadcrumb, Recover and WithMonitor now take a context as their first argument. Hints and levels are passed as options, such as sentry.WithEventHint(hint) and sentry.WithLevel(level).
  • Use ctx, scope := sentry.WithScope(ctx) to isolate data for a request or job, instead of cloning a hub or calling PushScope. Use sentry.GlobalScope() for application-wide data, instead of ConfigureScope.
  • Use sentry.ScopeFromContext(ctx) and sentry.ClientFromContext(ctx) to read the current scope and client, and sentry.ContextWithScope and sentry.ContextWithClient to attach your own, instead of NewHub and SetHubOnContext.
  • In Gin, Echo, Iris, Fiber and FastHTTP handlers, call the integration's GetContext(c) and pass the result to Sentry functions. GetHubFromContext, SetHubOnContext and GetSpanFromContext are removed.
  • Use sentry.ContinueFromHeaders(trace, baggage) to continue a trace and sentry.SpanFromContext(ctx) to read the active span. ContinueTrace, ContinueFromTrace, Scope.GetSpan and Scope.SetSpan are removed.
  • EventModifier and the Client.EventFromMessage, EventFromException and EventFromCheckIn helpers are removed. Use BeforeSend or an event processor to modify events.
  • Tags and a level set directly on an event are no longer overwritten by the scope.
  • sentry.AddBreadcrumb and sentry.LastEventID need a context that carries a scope. On a bare context such as context.Background() the breadcrumb is dropped and the ID is empty. Users should create a scope with sentry.WithScope first.
  • A context that carries neither a scope nor a span, such as context.Background(), no longer propagates a trace. GetTraceparent, GetTraceparentW3C and GetBaggage return an empty string for it, outgoing HTTP and gRPC requests made with it carry no trace headers, and each event, log and metric captured with it gets its own trace ID. Requests handled by the middleware and contexts from sentry.WithScope are unaffected.

  // Before: isolate a request
  hub := sentry.CurrentHub().Clone()
  hub.Scope().SetTag("route", "checkout")
  ctx := sentry.SetHubOnContext(r.Context(), hub)
  hub.CaptureException(err)
  
  // After: isolate a request
  ctx, scope := sentry.WithScope(r.Context())
  scope.SetTag("route", "checkout")
  sentry.CaptureException(ctx, err)
  
  // Before: use your own client
  hub := sentry.NewHub(client, sentry.NewScope())
  ctx := sentry.SetHubOnContext(r.Context(), hub)
  
  // After: use your own client
  ctx := sentry.ContextWithClient(r.Context(), client)
  
  // Before, in a Gin handler
  sentrygin.GetHubFromContext(c).CaptureException(err)
  
  // After, in a Gin handler
  sentry.CaptureException(sentrygin.GetContext(c), err)

• The Logrus and Zerolog integrations now take a context.Context. A client can now be attached to a context with sentry.ContextWithClient, so the separate client-specific constructors are no longer needed. The integrations now use the client initialized from sentry.Init. by @giortzisg in #1417
  • Logrus: remove NewLogHookFromClient, Hook.SetHubProvider, Hook.SetFallback and FallbackFunc. NewLogHook no longer creates a client or returns an error.
  • Zerolog: remove Config and NewWithHub. Client options move to sentry.Init or sentry.NewClient.

  // Before
  hook, err := sentrylogrus.NewLogHook(levels, clientOptions)
  hook := sentrylogrus.NewLogHookFromClient(levels, client)
  
  writer, err := sentryzerolog.New(sentryzerolog.Config{ClientOptions: clientOptions, Options: writerOptions})
  writer, err := sentryzerolog.NewWithHub(hub, writerOptions)
  
  // After: uses the client from sentry.Init
  hook := sentrylogrus.NewLogHook(ctx, levels)
  writer, err := sentryzerolog.New(ctx, writerOptions)
  
  // After: with a dedicated client
  ctx = sentry.ContextWithClient(ctx, client)
  hook := sentrylogrus.NewLogHook(ctx, levels)
  writer, err := sentryzerolog.New(ctx, writerOptions)
