0.38.0

Breaking Changes

Features

• Introduce a new async envelope transport and telemetry buffer to prioritize and batch events (#1094, #1093, #1107).

  • Advantages:
    • Prioritized, per-category buffers (errors, transactions, logs, check-ins) reduce starvation and improve resilience under load
    • Batching for high-volume logs (up to 100 items or 5s) cuts network overhead
    • Bounded memory with eviction policies
    • Improved flush behavior with context-aware flushing

• Add ClientOptions.DisableTelemetryBuffer to opt out and fall back to the legacy transport layer (HTTPTransport / HTTPSyncTransport).

  err := sentry.Init(sentry.ClientOptions{
    Dsn: "__DSN__",
    DisableTelemetryBuffer: true, // fallback to legacy transport
  })

Notes

• If a custom Transport is provided, the SDK automatically disables the telemetry buffer and uses the legacy transport for compatibility.
